:eek:hnoes
Hi there. My 2004 330d is not starting when hot.
I took it to a Bosch service centre and they told me that 5 of the injectors need replacing. Is it possible for 5 injectors to fail at once. The fault started without warning, not a case where it gets worse with time. The car starts immediately when pushed. Fuel consumption is normal, power seems normal. It starts in the mornings when the engine has cooled down after turning the key for about two or three seconds. I replaced the battery after the fault started, cleaned out the air filter( this seemed to help a bit?) and added a diesel additive that cleans valves and injectors. The problem still persists and I do not want to replace the injectors without some other oppinions.
I did not get any error codes or printouts from the service guy's. I was told that they had a printer error, That is why I dont trust them with their diagnoses.
Ps: I was quoted more about two thirds of the car's trade in value for new injectors. Is this a job that can be done at home?
:help

If it starts when pushed then your injectors are fine, I would say its your HP pump, for 5 to go at once nah dont think so, you say no codes? so its not electrical then.... HP pump, but do wait for other members opinions.

Thanx for the reply.
What about the fact that fuel consumption and power seems normal?
I would agree, highly unlikely that 5 injectors would go at once and if they did it wouldn't run normally after a push. Sounds like maybe a fuel leak around the common rail or air getting into the fuel system or a leak in the air intake. Check out all the little vacuum pipes around the engine, also check the larger air intake hoses for any splits. Have you changed the fuel filter and are there any funny noises from the fuel pump? Any fuel leaks visible? A fault code reader should show something.

I'm pretty sure changing five injectors won't cure it.

Thanks. I will have a look in the morning. I did not see any leeks below the car on the ground or any diesel smells. I will change the diesel filter and check the air hoses. What is the function of the cam sensor. Somebody on another forum had a simmilar problem, and it was recomended that he check out the cam sensor?

It just picks up the rotations of the camshaft, its possible but that would surely show up on an OBD check. Do you have anyone nearby with an OBD fault code reader? If not you can buy them off Ebay now pretty cheap (less than 100$) just make sure if you buy one it def supports your model.
They are a really good tool to have for modern cars, they don't solve every problem but can usually point you in the right direction.
BTW you can get injectors re-conditioned even if they are faulty so no need to buy new ones. I can give you numbers of UK companies who can re-con them as new. But again I don't think thats your problem, injectors are just magnetic solenoids opening and closing, if they were faulty they just wouldn't work at all even with a push start.

Just spoke with my buddy who is a head Landrover Technician, they use this engine in Range Rovers too, he says 100% its the camshaft sensor!! Replace it and problem solved. He says that is the only thing that will cause not starting when warm.

Problem solved. Good luck let me know if it works out. Cheers:)
