Another Aussie found you guys cause my 04 30dsport is running like a dog and now wont start at all obd shows a million codes but the main one looks to be cam sensor by what I can take form others experiences the other codes are as a result.

Will change this and see what happens

Had the car since new done 190k ( live in the country ) never missed a beat till now first became hard to start then was ok then ran rough then ok then died completely after limping home one night when it just started losing power and sounded to be running on 2 cylinders

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.

Mine 2002 3.0dA with 153 000 km just got out its inspection II last week, everything is allright except maybe the suspension wich start to be tired, I will change them for a full Bilstein kit this month.

Don't worry about a 70 000 km 3.0dA X5, it's just nearly new if you let it stock and fill the tank with a good quality diesel.

Chips Tuning is really hard for all the transmission because of the increase of torque, with the turbo because of pressure's increase and with the injection ramp because of the modification of the injection's time & pressure.

;o) Stf.

[victor2002]

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

[blueagle]

How much did it cost you to replace your turbo ?

The only problem I have with my 3.0D is not the engine- the flat tyre sensor possibly, because every now and on it just goes off when driving on a wet motorway and none of the tyres are bad. I've been to 2 mechanics and none of them could find anything, just said the air pressure was wrong. Well, it was not, because I check it every couple of weeks. \the problem started after I had alloys replaced to 19'' with wider rear ones (285/55/19) so I suspect the boys have hit something there while placing them and the mechanics were just too lazy to check. I'm going to the third one soon. Willlet you know if he find anything.
