E90 320i clutch judder - BMW 3-Series (E90 E92) Forum

NBTBRV8 · 08-13-2011, 06:03 AM

Has anyone had any experience of clutch judder in a manual E90? The car in question has done 65,000kms and has developed a bad judder. So it looks like we'll have to put a new clutch in it.

It's extremely common on all manual and SMG BMWs. Mine had a judder at about the same mileage and it's about the same at 160k mi. You do not have to put a new clutch in it unless it really bothers you. Just use about 1200rpm to launch the car and do it slowly. Also, replacing the clutch will not fix the problem. You need to replace the flywheel or resurface it. If it's dual mass, it's difficult to resurface. Most places will recommend against it.

It is worse when it is cold, as the car warms up is gets much better. The pedal also feels like it has only got half travel, at least not as I would expect.

Yup, very typical. However the clutch engagement point shouldn't move up too much. These clutches are self-adjusting clutches (SAC) which will keep the engagement point in the same spot even when worn. They don't always work properly though.
