Hey everyone,

I encountered a Strange issue with my GLA 45. I was driving my car normally like always (Calm) and then Parked it. Once i went to restart it the car started Knocking and Vibrating Extremely loud i thought that it might be the gearbox so i put in in neutral and revved it a bit but the higher i revved it the faster the sound got. Strangely after about 5 Minutes the Sound went away completely i thought okay cool problem solved and kept driving. I then Parked the Car for About an Hour went to start it again and the Sound was Back as you can see in the Video the Engine was still fully Warm. Then again after about 5 Minutes it went away. I did some test drives in Sport+ Mode and sometimes it feels like the Engine Power isn't all the way there or the turbo dosent boost fully the turbo also has a way higher whine the usual i think but then other times when i floor it the power is fully there. Would a Faulty turbo be causing this behavior / sounds i dont think it would ?

Or does someone know what could be the cause of this i am starting to get scared that it might be something big and that maybe i shouldn't keep driving this car i saw online that the M133 around 100K Kilometers likes to grenade itself

I also read the fault codes with Xentry and everything is clean no fault codes.

Thanks in Advance :)
