Hello.
Model: w212 2011 350cdi 4matic. Can anyone advise me what could be wrong.
My driver's seat isn't leaking, but left side pumping by itself. I found that the selected valve is not holding the pressure and leaking a little. So I decide to buy a used controller with the same number. But the same thing happens. I am worried about buying a new one if the controller is not causing the leak?
