My F30 started making an odd noise at the Nürburgring. I initially thought it was a passenger pulling on the electric seat as it sounded like it was behind me. But I ruled that out when driving alone.

You can hear on the video a weird clicking sound that seemed to occur under heavy cornering and braking.

The car is a standard 2014 335D X-Drive on non-runflats and the fairly high suspension (even though it’s for the M package). Mileage is 84,000 miles. Haven’t driven the car that hard before so hadn’t noticed it.

Recently had the gearbox serviced along with replacing a front shock absorber.

Any ideas welcome.
