Subject: [e36] RE: Cluch shudder
The history of the clutch shudder starts with the design of the E36.
In early 90s, BMW has decided to use a new friction material in the
construction of the clutch plate in order to reduce health hazards from
previous asbestos-based plates.
It seems that this new-designed material develops a glazing surface after a
certain period of usage. This means that the friction properties of the
clutch plate are affected and the coupling becomes rough (the clutch doesn't
have a progressive and linear coupling but a more "bouncing" coupling).
This is more evident at 1st and reverse gear coupling and is also dependent
on the clutch temperature (it seems to happen more often after a high clutch
BMW recommends the change of the plate for solving the problem - like
I had this problem last summer but it disappeared after a short period of
time (one month).
