Got a 2016 F20 118i that has a noticeable vibration through the steering wheel at around 120 km/h. Already had all 4 wheels balanced and new tires put on 5k km ago. The vibration is still there.
Its not constant - comes and goes slightly. More noticeable on smooth roads weirdly enough. No vibration at lower speeds.
Any ideas what else it could be? Driveshaft? Wheel bearing?
At exactly 120 km/h and through the steering wheel, I'd check:
Start with the brake discs. Put the car on a lift and spin the front wheels by hand, watch for disc wobble.
had this exact issue on my F21. turned out to be a slightly bent wheel that wasnt visible to the naked eye. the balance machine showed it as balanced but the wheel had a tiny lateral runout.
ask the tire shop to check wheel runout, not just balance. they need to measure it on the car with a dial indicator.
also check your front thrust arm bushings (also called tension strut). theyre a known weak point on the F20 platform and when they wear out you get vibrations and vague steering at highway speeds. cheap fix too, about 100 EUR for both sides.
