They are charging me 300 bucks for the job. Seems reasonable, how hard are these to change and how much would the part cost me if I went and bought it myself? The car is actually in Syracuse at Burdick Audi so fixing it myself is probably not and option since I reside in buffalo. I tried pulling the codes off the hvac controls when the car went dead before i had it towed, got nothing for the speed sensor so I had no clue what it was.

Died as in driving down the road and died, or died as in wouldn't start?

pump died on you. I would suspect you have a fuel pump issue and NOT a speed sensor. However, IF you decide to do the work the speed sensor PN is:

034 905 381A (its gray)

The G4 ignition timing sender is 034 905 381 (its black).

check then engine blink codes from the fuse/relay box under the hood (in the air plenum area).

It died while driving and would not start thereafter

I just replaced the fuel pump to avoid something like this since they are prone to failure at 100K+

Why would you ever take the car to the dealer?

SpencerB

My towing coverage is to the nearest audi dealer. I was 150 miles from home.
