Sound discharge valve c320
Hello! I have a C320 4 matic, when I go to 2000 rpm and release the accelerator the car blows intermittently on the part of the engine, as if it were a discharge valve ... they also sound a lot, do not lose strength or anything. The strange thing is that he does not always do it only once in a while... Has someone happened to you? Thanks!!
