- 2004 Mercedes E270CDI Elegance Saloon, 2004 C200 Kompressor Estate Avantgarde SE Sport Pack
Good afternoon Gents,
I’ve just purchased yet another Benz my 7th overall (an expensive hobby)
It’s a lot nicer than my previous and much more expensive E320cdi oh how I hated that V6 and 7G box, most unreliable!
Anyway the latest acquisition is a late 2003 53 plate E270CDi elegance. Shockingly it has a cloth interior. Drives very well, looks well underneath.
I’ve had to do a few jobs such as rewiring the mirrors and disabling auto fold and a thermostat.
Only issue it had now is a buzzing/droning noise coming from rear of the vehicle sounds very similar to the noise I had from a cheap non oe back box on my W210 E220cdi but it’s a genuine Exhaust.
It goes away as soon as a little throttle is applied seems to be worst between 1,200-1,500rpm then disappears. Worse between 30-50mph particularly on deceleration/overruns, goes straight away with the least bit of throttle.
I’ve noticed the air filter box buzzes a little at idle and will need some new bushings but this loud drone comes from
the rear. I’m pretty sure it’s not the Valeo or Rumble strip issue.
Any help without throwing parts at it!
