Hello,
I have a 2020 i3 since December, 4 times since I got the car I heard a loud knocking noise, and feeling a small shock coming from the rear of the car,
the car was stopped or parked so it's not coming from the movement/engine.
The first time it happened was when Bimmercode restarted the AC, when it happened I thought a pinecone fell on the car.
Then it happened without explanation 2 other times.
It happened again today, I thought someone with a bike hit the car.
It's like "chonk".
I went to BMW a few weeks ago, from the area the noise was coming they confirmed this could come from the AC, they did a quick check of the AC thinking maybe it was the compressor seizing
but without finding anything and it's running fine.
I checked today with Bimmerlink after I heard that noise, there is no error visible.
The car has a heatpump, the AC is always on automatic mode and used daily. (for 3 days now we went from heating to cooling the car).
Does somebody know what this could be ?
Thanks a lot.
