ECU, ESC, Hill hold, Parking break errors/faults
During Easter i went to wash the car, and following the wash while i was finishing some minor detailing while the car was idle, the engine turned off and started showing errors:
ESC Fault
Hill Hold Assist: Unavailable
Parking Break Fault (not every time though)
When trying to turn on the engine again, the car immediately turns of and the errors are shown, here is a clip of the errors and shutdown of the engine:
I turned in the car to an Audi dealer, and they told me today that they think it’s the ECU which has failed, and think this should be replaced — with the cost of £1750 + labour.
So i’m hoping someone here might have had a similar experience and identified the fault somewhere else which is worth reviewing before taking the plunge on a new ECU.
The car:
Audi A3 1,8 TFSI Quattro from late 2013 (2014 model/rev.)

I had this on a hire car and it turned out to be a sensor in the front bumper had not been connected correctly when they took the bumper off to replace a bulb. Check the front crash sensor is seated correctly, perhaps pressure washing has got water into the connections
Just an idea but worth a try

It’s a long story but I rejected the hire car before I drove it, they took it away and gave me a sharan instead
I complained and they carried out an investigation which lead them to advise me on the circumstances of the issue

Sounds like water ingress into a connector tbh, as its a bit of a coincidence this happening after a wash, check all connectors for residual water as tbh ecu’s dont really fail so much these days that easily unless externally affected per se.

I have exactly the same issue with my a31. 8.
Started a week ago but got progressively worse.
Did you ever find out what the problem was?

If it’s a list of errors that comes on when the car starts and then after a few seconds disappear (usually apart from Stop/Start), it’s likely to be time for a new battery!
If the engine starts and then immediately stops, I had a problem with the clip holding the fuel pressure sensor into the fuel rail rusting through and then the sensor popped out, along with a gush of petrol. Took me weeks to get the quid’s worth of clip as this happened during the first lockdown! Check this thread: https://www.audi-sport.net/xf/threads/help-fuel-leak.417193/
