Hello, first post on here. I recently purchased a my 2005 E Class and love it to bits, however there are two minor irritations. I will only list one of these on this thread and save the other one for another day.

My cars high pressure break valve is quite noisy and I have been told this is normal. I have taken it to my local Merc dealer twice and had it tested only to be told all is OK. The last technician told me that MB were aware of the problem and made an in line suppressor to quieten it down. Has anyone had this fitted and if so how much did it cost and has it worked ?
