Hi everyone - my wife was driving and got the "electronic system malfunction" message. We took it to Audi and 1.5 weeks later got a diagnosis:
Was wondering if anyone else had this issue and how's it holding up after.
I appreciate it

- coolant leaked into front drive motor through a failed seal
- Root cause of "electrical malfunction" error
- replace seal
- replace drive motor due to coolant leak
Was wondering if anyone else had this issue and how's it holding up after.
I appreciate it

That is the bad news.
The good news is that once the engine is replaced and the coolant chamber sealed. You will be better than new.
Just out of curiosity, is this a '19? I believe that the coolant leak was pretty much solved by the' 21.

This is not too uncommon. As A4Phil mentioned: be glad this happened within warranty, and it’s not something you should have to worry about again. Tbh, Audi knows this is an issue and if it happened out of warranty it should be covered.

I am wondering if there are other known issues - prior to purchasing the e-tron I did read up on some folks had the brake squeal. I had those replaced under warranty. Now it's this seal issue.
Thanks for all the assistance with this.

Brake squeal is an existing TSB. There is a sticky above with MOST of the e-tron TSB's. You can also request a "Campaign" printout from your Audi service to see which TSB's have been applied to your VIN.

I keep coming back to this sentence from Audi's 2018 materials under the thermal management section: "Effective cooling posed new challenges for the developers, particularly with the coaxially arranged electric motor at the rear axle. The solution is to supply the coolant via a double-wall pipe and its ceramic seal on the electric motor rotor."
