As above people , I am experiencing a very slight vibration / buzzing sensation through the steering wheel when the car , CLS 2010, is idling at its fully warmed 600 rpm.
Car stationary , gearbox in any position , AC on / off , foot on /off the brake it make no difference to the vibration.
Increase the revs by the slightest (625) and the vibration stops , above tickover it is as smooth as ever . With the engine cover off and resting my hands on the airboxes i can feel the same vibration so i am 100% convinced it is engine related.
As i do very short journeys the car very seldom gets warm enough to idle at 600rpm but recently i have been using the car more allowing it to warm up properly and have noticed this above issue.
No fault codes on the Carsoft , mpg unaffected but still terrible , no unusual engine noises apart from the usual diesel mechanical mayhem.
Thoughts , is this normal or have i got yet more work / outlay ahead ?
