Hi
My wife’s Audi 3.0 v6 TDi Quattro has been doing some strange things recently. Here are the main issues;
saying Tires under inflated
Stabilisation control (ESG) fault
Parking brake
Fault in braking system - contact workshop
Headlight something, can’t remember exactly what
Also happens: Steering heavy when trying to reverse, reverse camera didn’t work.
When it starts flashing all the warning signs, the car revs change, I can hear the engine changes, it runs differently.
Today: Speedometer kept dropping to 0 when driving, then rapidly moving up to 40 then back to 0.
The car has been steadily getting more and more faults. Our Audi specialist mechanic thought it was the battery, so that has been replaced and coded. This solved the problem for about 2 days. Then it has become worse.
I have read it could be a faulty main ecu? I have had a look at it and the outer box is very corroded, by the windscreen drain valve side.
Can anyone help? Is it worth trying to open the ecu to see if there is any damage internally? Eg water ingress? I’ve seen you can purchase special bolts to open the ecu.
Any advise would be very much appreciated. My wife is upset and I have 3 young children. I’m worried it will brake down in a dangerous situation. At the moment it hasn’t done that.
Many Thanks
