Happy Thanksgiving all. I hope you all enjoyed the holiday.
Maybe there's some good in the list/site going down. I learned more in
This is re; an A6Q 1995 (C4) auto. Over the last <2 years, 3 ignition
switches have been replaced. The original for the "non return to
start" bugaboo, and two more for a different problem - the car would
crank but not start, or crank-catch-die.
This weekend #4 was replaced.
This is getting to be a problem, and my mom (the owner/driver) is
getting scared to drive her car.
a) car cranks great
b) when it does run (its intermittent) it runs great. Might stall very
c) no pre-run of fuel pump in "run" position
d) no power to fuel pump/injectors/coil (e.g.: it is not a specific
problem in any one of those subsystems)
Its pre-OBDII so I have not pulled codes.
I've checked with Audi (field support engineering - called a friend at
home) and this car does not have an immobilizer, at lest not one that
they think works this way.
This weekend, after two prof mechanics were stumped, and after I spent
several hors looking over ECU wiring, harnesses, etc., I put a new
switch in and all was right in the world. Starts and runs perfectly.
So what could make switches die on 3-4 month intervals, after the
original going 8+ years?
