Hello again
Thought I would pop this in here not seat related but you lot are alot more helpful than the Merc forum
when driving I'm getting this intermittent fault it sounds like a blown exhaust but only happens once a week maybe for 10 mins doesn't matter hot or cold, Merc say they can't find anything.

Any suggestions please and thankyou
