Let me know how it goes today...

 

So far so good have started the car about a dozen times and no problems.

 

Great! Can you tell me where you purchased the part and did you install yourself? If so, was it difficult?

Thanks,

Bill

 

I'm going to go out on a limb and say my car is fixed. This is the part that fixed it.

Was about a 30 minute job unit is right under right side cabin air box in the sealed box.

 

Drivers side?

 

Do you have the install instructions? All I can find is the instructions for the 7 series and X5.

Thanks,

Bill

 

So when you saying right side do you mean passenger side?

 

I just wanted to say that I experienced the same problems plus a nasty engine misfire and I replaced the integrated supply module and all is well. Thats for the post guys

Thanks,

Mine no crank with idrive still working and headlights working was a faulty starter and new battery.

 

I had a similar problem:

2008 550i 6sp MT
without warning, it would just not start. Everything was normal in the cabin and there were no errors--the engine would just not crank. Like there was no power to the starter. Sometimes it would happen and then start after 2-5 retries. occasionally I would have to retry for 10-15 minutes before it would start. Then it would go days to weeks without any problem. I started to get more frequent. I took it to an indie shop and the only thing they found was 9 errors on the starter (about the number of no start episodes). They replaced it 2 weeks ago (after market warranty paid the $1300+). No problems since, but I am still holding my breath every time I hit the start button.

They said the starter is buried deep under the car.
