Fourth N55 HPFP problem I have heard about online. That's a low number, but not a huge number sold and a small number are online here. The later 2010 N54's seem to be fine.

The last few times I have let my car sit all day or overnight I've had long cranks, where I have to let off the brake to make it stop then try again a few seconds later. 2011 DCT.

Exactly, it looked JUST like your post!!! It won't turn over = it will not start.
I felt your pain when I saw your pic except my car is white........Also, since we are going on the close of Day 2 I'm almost certain they had to order one to replace it.

It always sucks to drop a car off at a dealer. You just never know what they are doing with it while it is out of your view. I hope you hear something back before the end of the day.

I had the same thing happen a couple times last month- also 2011 135 DCT. I took it to the dealer and they found no codes, and it started up normally every time they started it over a 3 day period. They thought it might have been bad gas. Has not happened since.

Just got the call........the official word is........they don't know what's wrong!!!
Will keep it longer for further diagnosis.

[Jseries1]

Yea it still won't start for them either. Don't know if that's good or bad.....

That's what I thought

I hope they find/resolve the issue and that you get it back soon.

Just to clarify, the engine turns/cranks, as the starter is working, but the engine won't start?

Or, nothing happens when the "start" button is pushed, meaning, the engine won't crank?

Either one results in a no start condition.
I'm just looking for some clarification.
Thanks.

I will post with the update. The scary thing is, I had no noted warning(i.e. long cranks). Motor simply won't turn over. Everything else is fine in the car. It only has 7k on it!!

We'll break out the umbrellas when they confirm it was actually the fuel pump and not what you have a hunch it might be?

"Just to clarify, the engine turns/cranks, as the starter is working, but the engine won't start?"
Bingo!!

[Jseries1]

Heard Back................Official answer......ECU replacement!!!!
They think that will work.....

[Brandon26pdx]

definitely a freak occurrence if that's the case.

[selmballs]
