Typical problems I have seen in my short time on X5 World are :

wont start usually down to an injector or injectors 'leaking back' (common problem);
wont start fuel rail pressure sensor;
wont start Cam sensor;
Wont start fuel pumps (any of 3)
Wont start fuel filter problem.

Problems with heater 'plugs'

Problems with aux ventilation (fitted as standard on European Diesel X5)

This is not an exhaustive list, however if anyone without a diesel tries to search for diesel problems you would spend a lot of time filtering them ot from everything else.

Is there a way we can retro link previous Diesel threads to this one now?

Many thanks

No issues with my E53 diesel engine as close to perfection as you can get IMHO well the new E70 3.0sd is better of course. It may not sound like the petrol V8 (only downside) but BMW diesel powered cars are probably the most capable vehicles in the world they provide a perfect balance between performance and economy. I get 28 -30mpg (UK gallon) on a two ton truck not bad eh and a 0-60 around 8 secs. For such an old girl none of the equivalent competitors can touch Q7, RR , VW, etc….

I drive an 02 E53 X5 3.0d and major repairs done so far :

1) FSR
2) auxilliary fan assembly
3) replace brake pads ( OEM brand)

Engine wise, just finished doing Inspection 2.

Major mod I did was replace exhaust to be like a 4.4/4.6 with tips exposed...

I have one question. I just upgraded my exhaust and installed exposed exhaust tips on my 02 E53 X5 3.0d. I painted my exhaust tips using high temp black spray paint. However, after a few days I noticed once the black exhaust smoke from the diesel exhaust mix with the high temp black paint, the paint starts to peel of slowly. Is there any other stronger high temp paint I should use or some precoating needed to spray to my exhaust tips before I apply the the black paint.....

why do you want to paint your tips painted black, they are suppose to be chromed, to give that nice elegant touch to de the exhaust. Why would you paint it black when the diesel fumes can take care of that.

Hi All

I am having some intermittent starting problems with my diesel x5.
Starts on the button every morning rain or shine, or whenever has not run for several hours.

At other times it can be problematic, sometimes taking 5-10 minutes to start after cranking every minute or so.

when driving, it is sweet and no lumpy idling.


I purchased a peake code reader and for those familiar with them, this is what I found.

From 'fc' (fault check mode) press 'go' and reader shows '52' then 'c' then 'ie' then '25' then returns to '--' (which I believe means no more codes found).

I understand this to be a code of ie25.

I cannot find this code anywhere in the accompanying peake booklet, do I need to convert it?

I suspect the starting issue is heat related on a resistor type / sensor item as when cold the car starts like a dream. Only when warm and used several times in the day do I get the problem.

Anyone help?

Thanks
