T5 Twin-engine Inscription, one week old. Wife reported a high pitch sound while driving on the motorway yesterday. She was on electric.
I'm gonna drive it and see if I hear the same.
I'm not sure if you guys identified a particular situation when that's most likely to happen.
WARNING: TwinEngine possible fault

Probably this happens depending on how many miles we did using the gas engine. Maybe even the regime is relevant (city vs highways)

@xc40_2020: This issue is purely an electric drive issue. I see other in this thread talking about pertrol engine oil. I must say that my pertrol engine oil is perfectly OK. The real issue was that the hyberdized tranmission which is really integrated with the electric engine had a catastrophic failure. The high pitch sound of the electric engine gradually increased in a period of perhaps 20-30 days, untill eventually the whole hyberdized transmission + electric engine failed completely. (see my video for the sound). The car would only move in Performance Drive Mode at that stage.
If you have a feelin that the high-pitch sound is increasing, it might be a suggestion to let the dealer open the bottom engine cover and have a look to see if they can identify any oil leaks from the hyberdized transmission + electric engine case.

Thank you Rocket. I didn't hear anything yet while I drive it myself. I'll keep an ear out.Rocket wrote: ↑Mon Nov 09, 2020 12:02 pm @xc40_2020: This issue is purely an electric drive issue.
