Occasionally, different types of noises can emanate from the seats. The noises can be of varying types, squeaking, rattling and clicking. This is because different parts in the seat come into contact with each other in an undesirable way. The presence of undesirable noises is also due to temperature, air humidity and the weight of the person sitting in the seat.
It is therefore important to question the customer as regards the character of the noise, in which situation it occurs and if it comes from the backrest or the seat.
The diagnostic procedure below should be carried out after customer complaint. The cause of the seat noises has been rectified on a running basis in production, which is why each procedure has its own VIN definition that is noted for each measure respectively.
The procedure list is divided into two parts, backrest and seat respectively. Procedure 2 for the seat should always be carried out, even if no noise has been reported there. This procedure can also be carried out as a precautionary measure in connection with other work on the seat.
