My mate has an 2000 year model E280. The engine was making a tappet noise so his mechanic (ex merc employee) changed all 18 tappets but the noise is still there. The engine is also slightly lumpy on idle. Yet the car drives extremely well. The car has been serviced regularly by Mercedes and has only about 60 to 70k miles on it. Does anyone have any ideas what could be causing the tappet noise?
