I mean the replacement of three hoses by modified ones.
Mostly, 211-customers are very satisfied with this modification.
For 230 (SL), those modified hoses are not available yet.
Because I am not English speaking it may happen that I use not the proper words when it becomes rather technical, here I am not sure that the word "hose" is appropriate.

what problem(s) do those new hoses address?

High frequency Noise and vibrations from SBC valves.

W210

When I took delivery of a 2004 E 2 months ago, the high frequency noise was rather noticeable.

However it appears to have quiet down, does it make sense to anyone?!

In additional, any fixes on the stereo static noise (which requires restarting the car)?

Much thanks for any feedback in advance.

It can happen if the car has been standing still for a certain amount of time.

Let your dealer check if the AGW already has software version 43/03 (but I do not think so because as far as I know for this moment it is only officially distributed by DCAG in Germany and it starts to circulate in neighbour countries...)
