rasping noise when pulling away....

[mercjim]

when i pull away the engine / or components < not sure which as it only does it when driving > is making a noise like the exhaust as a small hole in... like a rasping / boy racer exhaust noise....

had the car on the ramps at ATS and they said the exhaust is less than 6 months old and no leaks anywhere.....

it doesnt make the noise when stood still and engine being reved... but does as soon as i start driving... and its defo coming from the engine compartment....

ats said its possible the plates in the front box have dislogged and are resinating... but the noise isnt from under the car....

any help please?

thx

If it's an non OEM exhaust part(s) then it may resonate. Happened on my previous 124 when I fitted a replacement front section.

been told it could also be the water pump or the alternator making the noise... anyone else come across this?
