Hi,

my '00 E320t 4Matic with its 104K miles mark is getting expensive and
expensive ;-). I discovered a new thing - there is a high pitch coming
somewhere from the rear end. It is not loud but noisy enough to make it
very distinct to hear. Maybe not that high at the frequency but remains
constant regardless the gear, speed and rev.

Is it possible it is a fuel pump. I had just a week ago a service B
performed and IIRC the fuel filter got replaced.

Any clue what it could be?

Thx, Andy

For an MB of 10 years you may expect 3-5 percent of its orignal price
for repair costs.

Maybe the fuel pump or a leakage in one of the vacuum opening gadgets in
a back door or tank lock.
