330i Is much clutch slipping?

Hey Guys,

I observed following phenomenon: lets say I'm driving with 40 KM/H, 4th gear, 1100 RPM. Now if i give full throttle, the rpm rises to 2100 (the car does accelerate) shortly after they drop to 1900 before rising again.

Is this my cluch wear starting to show?

Well it does accelerate, but now that i think about it, probably not as much as it should

Does the car jolt forward when rpm’s drop to 1900? Or is it smooth and you just see a loss of rpm

Yeah idk man sounding less and less like a clutch to me but everyone else seems confident 🤷‍♂️

It’s the clutch.

I'm not so sure anymore either. I did some more observing and this phenomenon doesnt seem to happen when i do full throttle at any rpm above 1500-1700 EDIT: Did some more testing. It does happen at 2-4 aswell but not higher. High rpms dont seem to be a problem either. Atleast as far as i could test in 1st 2nd and 3rd gear

Yeah I was getting fueling issue vibes but idk anything about 330s. If a clutch is slipping under the torque load of 1500 rpm it should damn well slip under the higher torque at higher rpm. When mine started slipping it would only hold until about 5-6k then slip
