skellster 0 Posted March 28 Report Share Posted March 28 Hello When my 1 series goes above 75 mph it seems to start vibratating all of a sudden. It does the same thing above 5000 rpm. Any suggestions. It has only done 38000 miles Quote Link to post Share on other sites
Greydog 178 Posted March 28 Report Share Posted March 28 Hi Martin As you get the vibration at engine speed and road speed I would rule out (not completely) Tyres Wheels and Brakes my first thought would be the rotating parts in the engine bay. Check very carefully all pulleys belts and tensioners, water pump alternator pay attention the the crank pulley they have a bonded rubber vibration damper built in which have been known to deteriorate. Any imbalance in wheels tyres brakes or the drive train would show itself at set road speed not at increased engine speed Hope this helps Dave Quote Link to post Share on other sites
