Small vibrations during idle (z4 m40i)
I have an EU spec G29 z4 m40i 14.600 km in the clock.
During idle (engine fully warmed up) i feel small engine vibrations on the steering wheel (if i put my hand on it), or under my butt or under my right arm, if i put my arm on the center console. Idle RPM is around 700 rpm, software version: 2020-07. Other than HJS downpipe with 300 CELL HJS HD cat, car is completly stock. If i increase the RPM from 700 to 1000 for example, the vibration goes away. I guess that BMW i6 engine should be butter smooth even on 700 rpm idle as well... Is it normal? How do you feel your z4 m40i during idle? Maybe the engine mounts? Regards, Laszlo |
