Engine just started dying...
 

I'm new to this board, but did a search and didn't find a match to my problem... Anyway, my '98 Ti has been running just fine when suddenly, as I was driving out of a parking lot, the engine just died and the check engine light came on. Now I have to rev it to keep it running at all and will die quickly regardless of my reving it. The CEL is on all the time now... I changed the fuel filter about 500 miles ago so that's not a problem... I kind of assumed that the fuel pump is probably bad and I will go through the test routine when I have time but I wonder if any have any thoughts?

Thanks for your replies!

there are 2 sensors

Cam angle sensor

Flywheel position sensor.

These 2 will both throw a CEL, and cause the engine to stop running. Try to get a faultcode reading done, to see if it is this

and let us know what it was after ;)

I was thinking if the throttle body causes it. If it was dirty then clean it. Check also the base idle speed. Changing the air and fuel filter would be great.

the TB won´t throw the CEL. It wil just run rough..

If its throwing a CEL then there must be a sensor or some electronic faliure, registered as a code on the DME readouts.

Get the thing tested , and there should be a result out of that ;)

Mine did the exact same, it was either the cam or crank sensor I forget which.

Thanks to all! I'm going to run the codes and see what's going on... I'll report back..

If it throws a lot of codes... misfires etc. I would look info a new mass air flow meter, or try cleaning it.

Thank you for all your comments. I got lucky and got a Peake tool for cheap and read the codes. It was, in fact, the Cam position sensor. So, about $125 and 2 hours installing, I'm on the road again!!

Thanks again!!

That's good to see you got your hands dirty. So many get nervous with newer cars and bring it to a shop and get rooked.

Buddy brought his 99 M3 in they said $650 for the Cam Shaft Position Sensor, Laughed and did it for biers out on town.

Saved him quite a few bucks needless to say, now he won't be so quick to bring it in either.

Good job, man!

you gotta love OBD :)
