Have you looked to see if you have fuel pressure at the rail? That is where I would start. Do you have a code reader to read the code?

Diagnostic Trouble Light. Just another name for Check Engine light.

Thanks for the tip, should have mentioned that I did have fuel pressure.

I went back to the car and tried to start it and it started, but I have the check engine light on.

I made it home and scanned it with my scanner and it is showing a crank position sensor malfunction. Car would not start again after I shut it off.

So I have a new sensor in hand and a crude drawing as where it should be so I will tackle it tomorrow as the engine is hot right now.

This will be the first work on a German auto, all my experieince is with domestic.

Many thanks and I am enjoying reading the threads.

Bob

Installed the new crank position sensor, cleared the code and the engine is running like a charm.

What a little tricky sensor to remove and install. Not alot of room.

Thanks all

Good old CPS. I carry a spare. Of course mine has not failed - YET!

Engine won't start if it does not know where TDC is.
