Hi,
I have C180 w202 1998, Elegance, now with 73K miles on the clock.
Can anyone help please or at least put my mind at rest to the problem?
Over the last month, I have noticed a rattle noise at low revs and the engine is under some load. i.e. idling with air-con on or pulling away slowly.
The sound appears to be coming from the front of the engine, fan belt area.
Also I have noticed that it's idling slightly rougher than it used to.
The rattle is the same when the engine is cold or warmed up. Whilst at higher revs the rattle disappears and the engine runs smooth, even when accelerating hard.
When you put the steering on full lock the noise gets louder
Does anyone have any idea what could be causing this?
I have changed the serpentine belt (fan belt) tentioner as someone said it might be that.
All the other things connected to the belt (a/c, power steering seem to solid with no movement)
If anyone has any ideas it will be most appreciated.
Mike.
