My 2001 pre-facelift E46 325i (CKD) has rather creaky driver and front passenger seats since new. It creaks when it is sat on and when the occupant shifts his/her body (thus, it creaks during vigorous cornering!). It's very irritating (even my el-cheapo Proton Iswara doesn't have this problem!!). AB says its normal, and that applying leather care products would eliminate the noise. However, despite AB's advice, applying leather care products did not seem to help at all. It appears to me that the source of the creaky noise is the plastic cladding/cover for the manual seat adjustment levers at the side of the seat - apply some hand pressure on the cladding, and it creaks/squeaks.Is there no cure for this? Or is AB (and by extension, BMW) not acknowledging that this is a defect? Strangely, the facelifted E46s in the showroom do not seem to have the problem.I would appreciate it if other owners of the E46 (pre-facelift and facelift models) could share their experience and views.
