HA! Don't even get me started. Apparently it passed its local diagnosis and remote TAC inspection. We will see. Fingers crossed. I will say that I looked at the overflow canister before the service and it had about half an inch of coolant in it. Whereas for my last service it was full.
doesn't full coolant canister indicate leak? I think they just punting until it fails.... Did they tell you it will be covered under warranty if it does 6-12 months from now?

I believe that the answer to your question is yes. There is a leak. I also believe that Audi would say that is by design. The question is hiw much is too much? And to answer that you need to look at soooo many variables. (temp, pressure, hours it has been operated consecutively, stress compensating for front motor)
Audi claims to me that my rear motor is not damaged and that replacing the front motor will take work off the rear motor. That may solve the rear coolant leak. I will admit that my efficiency has jumped.
Finally, my rear motor coolant leak has been thoroughly documented by Audi. I have some faith that if it fails, Audi will cover it.

Glad you got the front motor replaced at last.
Re: the new front motor ‘taking work off of the rear’. Doesn’t the updated 2021 firmware now enable rear wheel drive only in steady state conditions in order to increase efficiency/range? That isn’t changing, so yeah: Audi passing the buck it seems.
Coolant leakage would be a function of the motor spinning, not of how much torque the motor happens to generate/apply.
This is how he explained it. The cars computer knows that the front motor cannot run in optimal fashion based on some parameter. So it uses rear motor to attempt to make up for that lack of power or whatever. Overall you see decreased efficiency. All I know is that with the front motor replaced, my efficiency has increased over what it was before. Beyond that simple Stat, I offer no conjecture aside from what the tech mentioned.
Here is a snap shot. Car turned in with bad front e-motor on 18 March. You can see it managing about 1.5. Then e-motor replaced on April 24 and the efficiency jumps.

If a defective front motor is replaced with a new one, it makes sense that your efficiency could increase.
I was specifically responding to the tech’s explanation about not replacing your problematic rear motor ‘because the new front motor will relieve stress on the rear motor’, or some such complete nonsense. Since the car defaults to rear wheel drive only in many situations, there is no way that the new front motor is going to somehow magically enhance the lifespan of your rear motor. It wasn’t replaced purely as an economic decision.
Does anyone have any evidence on the extended warranty for the front motor failure please so I can present this back to Audi UK?
Very similar situation here for me also, whereby the seal has failed and caused the front motor to fail as you are all experiencing. There has been various excuses made by Audi UK here however, they are now quoting £7,000 to conduct the repair.
This is a 2020 model and the issue is widespread but unfortunately not under warranty. What action can I take personally and does anyone have any guidance on how we can legally combat Audi to acknowledge that is it firmly their fault,.
More than happy to share further details but the guidance from this forum would be appreciated.
Just to let you know I have the exact same issue. 2020 model e-tron, front motor failed due to coolant flooding. I am based in Ireland.
I had a quick look and Irish consumer law on reasonably expected durability at the time of sale would seem to apply even though I am out of the 3-year warranty period.
Have you asked for the error codes for your vehicle? Mine mentioned the battery which might help because the battery has an 8-year warranty. Given the seal preventing coolant from leaking into the motor is mechanical, I assume that voltage issues could cause it to fail. If so then it would be the battery issue that caused my problems.
