First Diesel, 35d, Questions...
 
Never owned a diesel vehicle before. If I'm doing my own oil changes what do I need to know about the urea etc? I do know I can't just pee in the tank... :) Anyone have a source other than BMW?

Adding Urea To Clean Diesel Cars: Can I Just Pee In The Tank?

Proflyer 09-24-2014 02:05 PM

I just spent some time researching this as well, just picked up a 2011 X5d. The UREA is standardized per the EPA so ANY urea will work. The stuff at BMW seems to be a BMW style ripoff. I found 2.5 gallon jugs at autozone for $11.99. The tank seems to hold 6 gallons and will let you know when you have 1000 miles left basically. It should last a LONG time (oil change interval long). You can fill the tank yourself, get a good long funnel or even better get a cap/hose combo that'll screw into the jug. I found one that has a long clear hose and the ability to turn the flow on/off. I haven't tried to fill it yet but I think it will need it soon as the car only has 15,000 miles on it and has had 3 oil changes (one a year) but nothing shows them filling the tank...

i buy the 2.5 gal blue def jug from autozone which comes with a hose. depending on use, it will last a long time. Just don't forget that there are two fill points. Yes, i spill but i also just carry a bottle of water with me to rinse it off so no big deal.

As for my oil changes, I found that surprisingly, a dealer close to me sells the oil change kit (oil, filter, o-rings) for the same price as I could source online. Don't forget.. there IS a dip stick.

Thanks for the help guys. I just bought a container of the DEF and will try to find the fill system you describe Proflyer. I see the one fill point near the oil filter housing but can't find the other fill point. Do both points need to be filled? Yeah, it took me a while to find the dipstick. My M6 doesn't have a dipstick and I didn't think this had it either. Thanks again!

Here are some pics and diagrams

DEF system

The nossle near oil filter is for the passive tank. As shown in diagram above, the tank itself is pretty far down in the middle of the vehicle.

Here's the opening for active tank:

Experienced DYIers (lcapital, or zetatre) recommend never opening the Active tank to avoid debree and oxidation getting to it. Instead, always keep the Passive tank full (not wait for the 999 mile warning). That way, he passive tank never gets empty and thus sensor has no chance to get exposed to air. A few people have big problems with sensor getting encrusted with DEF after exposure to air.

^^ Good info.

Although I am skeptical of the 'dont fill the passive tank' advice. Filling it with fluid quickly; immersing it in fluid; ensuring it isnt partially covered then exposed would be the strategy to prevent crystalization. IMO. Once the tank is filled and closed the open space in the system will very quickly reach saturation. Be it one liter of space of 6 liters. No?

The problem is,once the transfer pump goes bad(and it does)the active tank will go under half mark before the "No start" warning comes on the dash.Mu pump went bad and now i fill the active tank every 1500-2000 miles and learn to live with the CEL.There is also a code for active tank temp sensor,so to get rid of the CEL it will be $750 for parts alone,that is wholesale price for the active tank and transfer pump.
