I have squeaking from that area- Micheal at the 500E meet tried detaching the plastic seat belt cover thing. THe squeaking still exists though. I think it may be from the seat springs.
The car has 52K on it.
I just was wondering if there was a general problem area to direct some lube towards- I would prefer no to spray a lot of lube and have the car smell of lubricant.
If anyone has a shot of the construction of the seats- like an upholstery redo picture that would be ideal to see where the lube should be applied.
