I was making a left and the car was EXTREMELY slow....I pulled over, shut off the car. I tried turning on the car again and the ignition works but the car is not turning on. Here are the codes I am getting:

17748 - Camshaft Position Sensor (G40) / Engine Speed Sensor (G28): Incor. Correlation
P1340 - 35-00 - -

16726 - Camshaft Position Sensor (G40): Signal too Low
P0342 - 35-00 - -

Is the engine spinning with the starter?

I hate to be thinking timing belt, but those codes are symptomatic...

I tried resetting the codes in vagcom and now all I get is:

16727 - Camshaft Position Sensor (G40): Signal too High
P0343 - 35-00 - -

almost like the starter is not engaging?

How many miles and when did you put the last timing belt in???

fkacct

went bad at around 49,000 and Audi replaced that along with tensioner and a few other parts, but no the belt itself. The car has 88,139 miles now. Is it possible for the problem to be timing belt related and yet enable me to drive from the left turn to a convenient stop?

Pray for sensor failure but sounds like Timing Belt to me, possibly skipped a few teeth and that allowed you to make the turn at reduced power before disaster struck.

TTschwing

While the belt may not have broken completely, it sounds like it shed a few teeth hence the cam position sensor error..

TTschwing

Cam is out of sync enough to bend a few valves slightly but still operate under reduced power.

I'd not try anything else at this point until you get it diagnosed as damage may be light at this time..

fkacct

Crap, I tried starting it a few more times.....hope that didn't damage it much more....

TTschwing

It's much better when it fails this way. You'll still need to pull the head and replace the valves. Redo the TB stuff etc. When they fail suddenly at speed they often take out the head and pistons too..
