Hi
My Q7 e-tron was hauled away on a truck today back to Audi. Did about 400Km faultlessly on Saturday, got home, parked up & plugged in. Got in this morning it gave a drive-train error, and advised me to stop and not exceed 2150RPM.
Considering nothing was moving, and no engine running, this was strange.
Audi Assist hauled off the car, but before it went I did a quick scan. The 2 relevant parts are below. So it looks to be something to do with electric motor controller?
Really strange as the car completed the last Km of the trip home (250Km) on EV, and everything was perfect.
In fairness the local Audi garage were helpful, but busy, so it might be a few days before I get a diagnosis. Needless to say there are very few e-trons about
But somehow this feels like a glitch. I would have been tempted to clear the messages and see what happened, but that might have been difficult to explain.
I have 45,000 Km covered and it's been totally fault free, not a hint of an issue. A bit worrying when something potentially leaves you stranded.
