Symptoms of fault
Seats rocking or sliding forwards and back as you accelerate and brake. Wobbling or excessive movement. This is a very common fault with all Z3 models.
The problem
The seat rail bushings wear; causing excessive seat movement.
The poor quality rubber bushes within the seats sub frame tracks wear, perish or completely disintegrate and ultimately fail causing excess movement in the rails. This causes the symptoms noted above. This is a very common fault with all Z3 models. OEM replacement bushes if fitted would just fail again as these are also made from a poor quality rubber not suited to the application.

Z3 E36 E37 E38 1994-2002 Roadster and Coupe.
