Hi guys, so I have been driving and loving my M4 (2015) for 8 months with a slight annoyance, which I was going to try to fix when I take the car for service the next time. So the issue is that in a right turn or on uneven road or over traffic bumps when my body leans to the left the left side lumbar support touches the centre console and it makes a squeaky noise something like rubbing an inflated balloon. So yesterday at Leo Haese in Centurion there was some technical guy from BMW HO and he had a look at the issue. He said the noise may be coming from the internal parts in the lumbar support, but he was not sure. Any way the car is going back for service so they can have a look at the seat. There is no issue with the passenger seat. So the question is has anybody else experienced something like that. Regards.
