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.

Appricate the input/help :)

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

Would be great if that is the case! Did the car you're referring to also cut off the engine?

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.
