SLK 200 Engine Rumble
Bought my 54 plate SLK 200 21k miles four weeks ago and am very pleased with it but for one concern I now have.
On a morning cold start, I've began to notice a 2-3 second low level noise rumble from the engine which then disappears, I guess due to the oil pressure building up. If the car is left 3-4 hours during the day its also noticeable on starting the engine then.
From past experience, it sounds like big ends knock albeit not loud. However, how can that be with a relatively new and low mileage Mercedes engine !
So question is, am I being paranoid and / or is this typical of these cars?
My neighbour is an ex Mercedes mechanic and he commented after listening to my car that he'd never heard that noise on a Merc before.
