SOmething else to add to my 'service instructions':

"No permission to operate on public roads
DO NOT WASH
DO NOT DETAIL
DO NOT touch the DEF"

Sounds like that urea system is a bit of a pisser.

Thanks a lot for all the answers. And special thanks to "5352X5" who sent me a guide and link from Germany!
And I promise not to be too hard to the dealership and I haven't been so far. But a little pressure doesn't hurt since they forgot to do the oil change in the first place AND messed up my USB port....
Thumbs up for this forum!

[2010X5d]

I got about 5400 miles on my 2010 35d. Three days back I got a warning message "No Start in 992 miles". It was there for a min and after I pressed OK it was gone.
I took it to the dealer, even they were not sure what it was and after talking between themselves and me explaining about what DEF is ( thanks to this forum ) they checked and finally gave me in writing as 'both tanks at same level'

Just concerned...am I OK ? or do I get stranded in any place due to this ignorant BMW service people?

So did they tell whether they were both full or both empty

Seriously, a written statement of 'both tanks at the same level' is a new low for BMW service dept. communications incompetence. I'm not sure how a 35d owner should interpret such an ambiguous statement. Same % full, same # of gals.

The only way I'd be happy with a 'both tanks at the same level' explanation is if both tanks had 1.5 gals. in them. IOW that there was still 3 gals (out of 6.5 capacity) left. And OBTW, the small tank is full, hence the transfer for DEF from the large to small tank has been working correctly

Well, I printed off the above document, and guess I will take it the dealer with me. 2200 miles and I received the no start warning. Hopefully I won't end up arguing about this at the dealer. This is all totally unacceptable. This vehicle, 2010 X5 35D has not been driven hard at all......very easy. Fairly warm temperatures the last couple of months that I have had it.

I even asked them during delivery, to insure both tanks were full (based on what I had been reading here, with potential issues at the factory with the idea that perhaps the passive tank wan't being filled) "They" checked...said it was ok......but don't really know how they checked it. Since there is no dip stick. If this is going to be the norm...I am going to learn quickly how to do this myself.

Sorry about the link. In the paragraph dealing with DEF, it says during the 4 year free maintenance period the filling of DEF will be taken care of. It doesn't distinguish that it will be done only during oil changes. It just says it will be covered. It is quite a lengthy article....but you can scroll down and I highlighted the key area. Didn't mean to highlight it quite so much...but it is easy to find.

By the way....since my original post about getting the warning at 2200 miles, I went out and started my vehicle for the 3d time since receiving the message, and low and behold....no warning. It had cleared. I have read in other DEF related forums about this happening to others.....and they even later took it to the dealer who was unable to pinpoint any issue, including any message of a warning. If mine continues to show no message....I think I will just monitor, unless someone thinks I need to run it in to the dealer.....

2010 BMW Advanced Diesel - X5 xDrive35d and 335d Sedan

01.01.2010Press Kit
Information from editor: Update effective January 1, 2010.
BMW X5 xDrive35d and 335d Sedan continue to impress with outstanding performance and efficiency
Woodcliff Lake, NJ – January 1, 2010… In 2009, BMW embarked on a new chapter of its EfficientDynamics story with the introduction in the United States of two models equipped with the BMW Advanced Diesel with BluePerformance technology – the X5 xDrive35d and the 335d Sedan.
The wide availability of these vehicles marks a significant milestone in the BMW EfficientDynamics strategy, which seeks to offer customers in automobile markets around the world maximum driving pleasure with minimum fuel consumption and emissions. Both models meet the emissions requirements in all 50 states.
Both the X5 xDrive35d Sports Activity Vehicle® and the 335d Sedan feature BMW’s most sophisticated six-cylinder diesel engine, the 3.0-liter inline-six featuring Sequential Twin Turbo Technology – an engine widely acknowledged as the unchallenged benchmark for sporting performance, refinement and superior efficiency in other markets around the world. This engine produces 265 horsepower @ 4,200 rpm and an impressive 425 lb-ft of torque between 1,750 and 2,250 rpm. To put that later number into perspective, that is nearly as much torque as produced by the 6.0-liter V12 in the previous generation 760Li.
In order to ensure full compliance with the demanding emission standards in California and other US states, BMW uses SCR technology to reduce nitric oxides (NOX).
Leading the way:
BMW diesel competence for the US.
The history of BMW diesel engines began in 1983 when the BMW 524td was introduced as the fastest diesel in the world at the time. The 524td was sold in the US for the 1985 and 1986 model years and offered significantly better performance than more widely known diesel competitors. From that starting point, BMW has spent 25 years continuously developing diesel technology. Today’s BMW Diesels are characterized by dramatically improved power and performance; fuel consumption and emissions levels – reflecting the principle of BMW EfficientDynamics in every respect.
Through their refinement alone, BMW diesel engines have helped to significantly eliminate reservations regarding the acoustic properties of a diesel engine. In fact, great demand for BMW diesel engines has helped BMW achieve increased market share not just in Europe, but in regions all around the world. Today no less than 67 percent of all new BMWs delivered to customers in Europe are powered by a diesel engine.
While diesel engines of today represent an impressive standard for fuel efficiency and emissions on the whole, BMW Advanced Diesel engines take this a step further, setting the standard for torque and pulling power that could never be achieved by a similar displacement gasoline engine – while consuming 25 percent less fuel on average than an equally powerful gasoline engine.
New generation of diesel technology:
Maximum responsiveness, minimum emissions.
Maximum power, outstanding efficiency: The first BMW Advanced Diesel with BluePerformance is particularly well-suited to combine the driving dynamics and refinement of a premium automobile with the most current and demanding standards for preserving resources and reducing emissions. Featuring exceptional power and torque, the 3.0 liter inline-six diesel is one of the most fuel-efficient engines in its class.
Applying Sequential Twin Turbo Technology, a small turbocharger first spools up at low engine speeds. Thanks to its low inertia, this turbocharger develops boost (and extra power) in response to even the smallest movement to the accelerator. As engine speed increases the second, larger turbocharger begins to spool up and at mid-range engine speeds both turbos work together. At higher engine speeds boost comes exclusively from the larger turbo which enables this engine to develop maximum torque of 425 lb-ft at just 1,750 rpm. Interaction of the two turbochargers is controlled by the high-performance electronic engine control unit.
In addition to the above Sequential Twin Turbo Technology, new technical highlights of BMW Advanced Diesel – presented for the first time in 2007 – include an aluminum crankcase and third-generation common-rail direct fuel injection. Featuring precision-quality piezo-injectors to deliver the precise dosage of fuel into the combustion chambers with the smallest volume of pre-injection, this third generation system ensures a particularly clean injection process with optimized fuel consumption, emissions and running smoothness.
Given all of these qualities, BMW’s 3.0-liter diesel with Variable Twin Turbo has won the prestigious International Engine of the Year Award multiple times – more than any other prize or acknowledgement. In its first year on the US market, this engine won a covet Ward’s “Ten Best Engine” award.
In spite of its popularity in Europe, modern clean diesel technology is still a new phenomenon. Mindful of that, BMW’s diesel engineers invested additional energies in making the engine even quieter for the US market. Additional sound insulation was added. Wrist pins on the pistons were moved slightly off center to improve engine smoothness and quietness.
The BMW 335d Sedan featuring Advanced Diesel with BluePerformance offers maximum output of 265 hp and peak torque of 425 lb-ft. On the road, this means acceleration from 0–60 mph in six seconds flat and an EPA fuel economy rating of 23/36 mpg (city/highway). The 335d Sedan is not only the most fuel efficient BMW in the line-up today, but is the most fuel efficient BMW ever offered in the US.
Like the 335d, the X5 xDrive35d offers sporting character through BMW Advanced Diesel with BluePerformance, while standing out as a high-torque Sports Activity Vehicle® with excellent qualities for long-distance motoring. The BMW X5 xDrive35d accelerates from 0–60 mph in just 6.9 seconds and offers an EPA fuel economy rating of 19/26 mpg (city/highway).
Based on their highway fuel economy ratings, both BMW Advanced Diesel models can travel up to 585 miles on a single tank of fuel.
Most advanced exhaust gas management:
Selective Catalytic Reduction.
To optimize emission management, Advanced Diesel with BluePerformance incorporates an oxidation catalyst placed just downstream of the exhaust manifold with a diesel particulate filter housed in the same unit and a Selective Catalytic Reduction catalyst with urea injection. In addition to filtering out even the smallest particles from the flow of exhaust gases, this combination ensures effective reduction of nitric oxides (NOX) by way of a chemical reaction within the exhaust system initiated by the injection of a small dose of urea referred to as Diesel Exhaust Fluid. The ammonia (NH3) generated in this process within the SCR catalyst subsequently converts the nitric oxides (NO and, respectively, NO2) in the exhaust gas into environmentally compatible nitrogen (N2) and water vapor (H2O).
SCR technology by BMW:
Optimized emissions without requiring additional maintenance.
To introduce SCR technology in the vehicle, BMW has developed a two-tank system ensuring convenient use of this new technology with all the benefits and ease required by the customer. The amount of Diesel Exhaust Fluid required in each case is injected from the active tank (approximately 1.6 gallons in volume) by means of a dosage pump. Since the DEF would freeze at a temperature of 12oF this active tank, as well as the dosage pipes are heated.
The active tank is connected to a second reservoir, referred to as the passive tank. With its additional capacity of approximately 4.5 gallons, this passive tank offers a plentiful supply of the DEF. The average range provided with this supply capacity is generally sufficient to have the tank system replenished only when the driver needs to change the engine oil. Hence, the large amount of DEF stored in the reservoir enables the customer to enjoy continuous driving, without having to change his/her service intervals. The driver therefore benefits from the advantages of this environmentally friendly emission technology throughout the entire running life of the vehicle typically without any additional service or visits to a BMW Center. Since all BMWs sold in the US benefit from The BMW Maintenance Program, the refilling of the DEF tanks will be a no-charge service for the first 4 years or 50,000 miles.
DEF from the active tank is delivered to the dosing valve and atomize into the exhaust system. Consistent distribution of DEF within the flow of exhaust is ensured by the SCR mixer. The ammonia generated in the hot exhaust flow subsequently acts as a reduction agent in the SCR catalyst and converts environmentally harmful nitric oxides into nitrogen and water vapor in a process referred to as a selective catalytic reaction (SCR). This process gives the special SCR catalyst its name.
The control of the SCR system is masterminded by BMW’s powerful engine management computer. A nitric oxide sensor downstream of the SCR catalyst provides feedback on the concentration of NOX in the exhaust emissions.
Due to packaging limitations, the position and location of the DEF tank and refill port varies from one model to another. In the BMW 335d, the active and passive tanks are at the rear of the car, while in the BMW X5 xDrive35d, the active tank is housed in the front right section of the engine compartment, and the passive tank is under the floor next to the transmission. The refill ports in both models are easily accessible to ensure that, should the need arise to replenish the supply of DEF before a scheduled service visit; this can be accomplished neatly and easily.
BMW diesel misfueling protection:
Helping to avoid a costly mistake
The popularity of diesel vehicles has lead to the unfortunate incidence of diesel drivers accidentally refuel their vehicles with gasoline. In order to avoid this, BMW developed a diesel misfueling protection system. A typical unleaded gasoline refueling nozzle has a diameter of 21mm (0.83 inches) whereas a typical ultra-low sulfur diesel refueling nozzle has a diameter of 24 mm (0.94 inches). Both the X5 xDrive35d and the 335d are equipped with a spring-loaded flap covering the refueling opening. If anyone attempts to insert a refueling nozzle that is smaller than 24mm, the door will not open, preventing the accidental insertion of an unleaded gasoline nozzle.
In the event that a driver encounters a diesel pump that has been fitted with a gasoline nozzle that the protection system will not accept, each BMW Advanced Diesel comes with an adapter housed in an air-tight container.
BMW’s competence in diesel technology:
A story of success since 1983.
The performance and fuel economy offered by new BMW Advanced Diesel with BluePerformance is a further example of the exceptional potential this engine concept has to offer. In recent years BMW has worked continuously to further the development of its EfficientDynamics strategy. As a result, BMW has consistently enhanced the benefits and attractiveness of diesel technology, increasing engine output (performance), while reducing fuel consumption and emissions.
The story of success of BMW’s diesel engines is characterized by numerous milestones in technical development, dating back to 1983. Back then BMW presented the first inline-six diesel in the history of the company, with maximum output of 115 hp and peak torque of 155 lb-ft.
The BMW 524td that featured this engine was acknowledged as the fastest diesel of its time and was the last BMW diesel model to be sold in the US.
In the intervening years, BMW’s engine development specialists enhanced a wide range of innovations, ensuring their alignment with series production standards, increasing power and performance, reducing fuel consumption and emissions in the process. In 1987, for example, BMW introduced Digital Diesel Electronics followed three years later by BMW’s first diesel engine with an oxidation catalyst.
BMW diesel engines:
Making a unique contribution to The Ultimate Driving Machine.
Right from the start BMW’s engine development specialists recognized the potential of diesel in enhancing efficiency. They focused on the unique performance characteristics offered by diesel, providing an entirely new concept of The Ultimate Driving Machine. Above all, they used the performance of the diesel engine to develop superior torque from low engine speeds.
As a result, the BMW diesel was soon able to offer its unique sporting character – in everyday driving situations, as well as on the race track. A BMW was the first diesel-powered race car to win a 24-hour endurance race when a BMW 320d won the 24 Hours of Nürburgring in 1998.
In the same year BMW presented its first diesel engine with direct fuel injection ensuring even greater spontaneity in the development of power. In the process, the precise dosage of fuel helped to reduce fuel consumption and optimize combustion in the interest of even greater smoothness and refinement. Ultimately, given these qualities, the BMW diesel was appropriately prepared for the luxury performance class, with the first V8 diesel engine featuring direct fuel injection, which made its debut in the BMW 7 Series luxury sedan in 1999.
Milestones in progress:
Common-rail direct fuel injection, Sequential Twin Turbo Technology, maintenance-free diesel particulates filter, BluePerformance.
In the years that followed, BMW made significant – perhaps revolutionary – progress in the areas of injection technology and diesel turbocharging. As early as 2001, the second generation of common-rail fuel injection pumped fuel into the combustion chambers at a pressure of up to 1,600 bar, or over 23,000 psi. In 2004, the BMW 535d became the first car to feature an inline-six diesel with Sequential Twin Turbo Technology.
BMW also introduced the second generation of the diesel particulate filter now featured as standard equipment in all its diesel models. The exhaust gas-cleaning unit is positioned directly on the exhaust manifold itself in order to ensure optimum efficiency very quickly and smoothly. The particulate filter does not require any maintenance and regenerates itself by incinerating the diesel particles. This filtering function is performed at all engine speeds and under all loads, without any reduction of engine power or increase in fuel consumption.
BMW’s current range includes a number four-cylinder and six-cylinder diesel engines. Both the six- and four-cylinder engines have aluminum crankcases helping to significantly reduce the weight of these engines. A traditional handicap of the diesel engine, which adds weight due to the use of a cast iron crankcase (a much heavier material than aluminum), has nearly been phased out completely. The reduction of weight enhances the car’s agility and, as a result, the sporting character of BMW’s diesel models.
Comparing the first six-cylinder BMW diesels from 1983 with the most powerful diesel engines of today, one can easily appreciate the progress made. Consider the following facts and figures:
Maximum output of the inline-six engine is up 135 percent, maximum torque is up an even more impressive 170 percent. And despite this immense increase in power and muscle, average fuel consumption of the 3.0-liter engine featuring Sequential Twin Turbo Technology is 20 percent lower than diesel engines of 1983. At the same time, exhaust emissions have been reduced dramatically, thanks to several new technologies. For example, a BMW diesel in the 2008 model year generates only 1 percent of the particulate emissions originally contained in the exhaust gas of a 1983 diesel model.
The world’s most sporting inline-six diesel:
On the road today in the USA.
Despite these impressive facts and figures, BMW is continuing to upgrade the diesel engine to an even higher standard, and BMW Advanced Diesel with BluePerformance marks the next stage of development. This innovative technology now also fulfills US market demands in terms of power, performance, running smoothness, efficiency and emission limits.
The 2010 BMW 335d has a base MSRP of $44,825and is eligible for an alternative fuel tax credit of up to $900. The 2010 X5 xDrive35d has an MSRP of $52,175 and is eligible for an alternative fuel tax credit of up to $1,800.

There is prob. some shite in the owners manual that says DEF is only refilled during yearly service or some other excuse. The purchase agreement you signed likely says that the owners manual supercedes all other written or verbal communication, yada yada BS. This is the kind of crap that made me pass on Merc Benz for the past 15 years... Voting with your wallet is your ultimate hammer.

[dmfelger]

My 35d was not in sync with the oil change, but the dealer covered it under a "courtesy" charge. Said the other dealer should have serviced it when the oil change service warning hit. Just over 12K miles when the DEF warning came on.
