Odd warm restart problem
Posted: Wed Feb 05, 2020 6:01 pm
Hi all
I have a 2000 C5 S6 (not RS6) but im hoping someone here can help me as the cars share quite a lot of parts and the S6 forum is dead. When I bought the car it was filled with problems but im pretty much there now, just got one niggling issue,
My car struggles to start but only under the following conditions:
When I start my car from cold it starts on the button
When I restart the car once running it starts up again fine
When I start the car after it's been sitting for an hour or two, it really struggles to start up again. I have to give it a bit of throttle on startup then it springs into life ... once it's running it's fine. There aren't any other noticable problems with the car.
The battery was replaced by the previous owner in the last few years so I dont *think* theres a problem there but its possible, I dont have another battery big enough to test with..
The car has a Bigas LPG system fitted but it does it whether LPG or Petrol is selected so I dont think the problem lies there (although also a remote possibility but wouldn't be my first guess)
Vagcom isn't giving me any error codes.
Anyone had a similar issue with their car? I did see a few threads online for other Audi models of similar era where the crank position sensor was the culprit, but wanted to see if anyone specifically with this era of V8 had any ideas..
Thanks in advance
Ben
