I have a 2000 A6 Quattro and am finding a correlation between the
weather and the functioning of my car. Currently, I am getting the
following errors: ABS - Brake - Check Engine/ The ABS and Brake
lites come on and occasionally go off again. The Check Engine seems
to come on and stays on. I went by my local mechanic and he reset the
check engine lite once noting that I apparently had the following
1. Vacuum loss in fuel system
2. Two separate faults in Oxygen sensors
3. Brake module bad
This mechanic handed me a $2000+ estimate and told me that Audi's
frequently commit electronic sepuku. [his words] I'm a bit more
skeptical of him than I am of Audi.
I highly doubt that all of these came into play simultaneously without
lightening striking so I'm suspecting computer problems.
Note: the car was in a mild collision over the summer and the rear
left fender was bent slightly... some possibility of water getting in
