No issue mine has whistled from brand new asked the dealer this early in the peace but was assured all ok

Hi, AussieX5,
bad cam shaft sensor (CSS) causes that the engine cannot start. Once the engine runs the signal from the CSS can be lost totally and the engine will not stop and runs smooth BUT next starts are then impossible with CSS signal lost. The rough engine run and engine stalling can cause bad crank shaft sensor. Be aware that not only the bad sensor can cause the fault code to appear. It can be just wiring harness problem and the sensor may be OK. Check all points for proper connection.

Find meaning of all OBD2 fault codes and use a common sense as well and that will help You find a root cause.

Thanks for that guys unfortunately she went on a flat bed this morning replaced the sensors waqnts to start but wont the guy replaced the fuel filter as well said it was blocked but I suspect there is a large quantity of air in the system now as he did not fill the filter before replacing it and when tested there was plenty of flow so far theres a thousand bucks spent and it's still not going ??? cleared all the codes and tried to start just showing low voltage code now as the battery is stuffed now fuel inject warning gone as is the cam code so what next ??

waiting on the dreaded phone call from syd diesel center as I sent it there being told they are the bees knees in modern d's

well see

AussieX5, to vent fuel system after fuel filter replacemnet it is enough to do this (according to BMW TIS):
- no need to fill the filter
- after filter replacement turn the ignition on for approx. 1 minute, the fuel pre-supply pump is activated and the fuel cooler and filter are filled with fuel and vented

If You run out of fuel, the Car user guide says:

- "... the diesel fuel delivery system should not be vented at normal circumstances even You ran out of fuel. If You are experiencing starting problems after this situation, activate the starter for approx 20 sec." (My translation to english)

The starter should sustain this long run at ease because there is another hint in the user´s guide for starting at very low ambient temperature:

- after glow symbol goes off, activate the starter for up to 40 sec until engine starts

I have heard different versions about the reliability of X5 E53 and understand it should vary from case to case due to individual care of cars and other factors.

but in general, for 2004 3.0 Diesel sport Auto with 70,000 km on clock, with good care, how long should I expect to keep it until maintain/repair bill and breaking down start destroying the fun of having it? I still have 2 years 10 month factory warranty on the car.

My particular case is the blown off of the turbo, other than that, the engine runs great, lots of torque and hp's, and good enough mileage

How much did it cost you to replace your turbo ?

[quote=RichardPB]I have done 34k from new (now 2 years old) and I still have 2 green service bars (brake fluid square is up so that will need doing but was waiting to have it done with oil service). I am due to take the car to Europe and will do 2.0k or so in 10 days. Should I wait for bars to disappear before servicing, when can I expect the next service to be due (lights to go out) this will only be its 2nd ever service so what’s involved?

I would definetly do the service before going to Europe. I had the same dilema in june- went through the whole Europe without any probs, but did the service beforehand despite it was not due yet by one green bar. From what I've been explained by the mechanic- the car calculates the time for service on the basis of 4 factors, but I don't remember which. Whatever they are, the last thing you want is your car starting showing you the service messages or anything like 'please contact the service', when you are in the middle of another country. Besides some funny insurance companies in UK will not cover your break down on German motorways even if you purchase such cover, they will only pay for towing from the end of the motorway to the garage up to certain amount in euros and for towing on motorway you would have to pay yourself. Just another reason for having service before such a long trip.
