hello
my 99 e240 v6 estate has recently started to make a noise, it difficult to describe/diagnose like this I know but will have a try!
it appears to be coming through the middle area of the car, back of engine through central vents etc. the sound is a kind of whine but can also sound a bit like when a worn to metal brake pad is scraping against a disk, it isnt! most pronounced accelerating at low speed & even more so when letting off the throttle from a higher speed, it will also do it when slowing down & in neutral. my immediate though was prop or transmission, but in neutral??
that do you think?

I know on the 203 the the parking brake cables and heat shields can come away and touch the prop shaft,,One a 202 it could just be a heat shield, and these are easily put back with self tapping screws

a screw had come through the heat shield, replaced with addittion of large washer. still making the noise, so probably not this.
