Just got home from a harrowing driving experience. I have an Audi A4 2001, 1.8T, 68,500 miles and it totally shut off when I was driving at 50mph and I almost crashed.
I replaced the MAF and O2 sensor a month ago.
Can someone tell me what really is going on?
Is it the ignition coils? Is it the fuel pump?
I'm so startled....HELP!!!

 

more details have you check, spark fuel pressure etc. sure you werent doing dounuts and hit a curb and made the fuel cut off switch trip

 

No I wasn't. I was just driving normally headed home from work.
Could my fuel injectors or spark plugsbe dirty?

 

Is the car still running? If not don't keep trying to start it timing belt might have gone.Pop the front cover in front of the motor to check the shape of the timing belt formissing teeth.

 

Yes, it's still running.
Looks like I gotta feed it lots of gas, while it's in Neutral,to run.

 

I should have said event if the car is still running to check the timing belt.Its one of the most costly repairs around here and usaul happens between 60-110 thousand miles.you might have just thrown it one tooth off.If the timing belt goes it can go at just an idle and stall.If you try starting it up and more teeth break off the pistons will slam the valves in the head and bend them.It costs about $4000 to replace the parts if this happens $700 if you just need a timing belt.I hope its not that but you better check it out!

 

Agree with above. Sounds like timing belt skipped a tooth.

Check for codes and have the car flat bedded to check the timing belt. Don't run the car until the timing belt is checked.
