Hi Folks, I have just (reluctantly) traded-in my CLS for a manual C220 (2014). Got it home and parked on our drive which is on a reasonable slope. Switched-off, put the car in 1st gear and put the foot brake on. Before I could get out the car very slowly crept forward, and then lurched forward, this repeated 4- 5 times before I put my foot on the brake pedal. Reversed-up and tried again, making sure the car was in gear - same pattern of events. Even tried parking the car in reverse gear - same thing. My 'other car(Skoda Octavia) has no problem holding in 1st gear with the hand brake applied. Went back to the dealer, got them to find a relatively steep hill and try same. Discovered that the footbrake applies a firmer 'brake' with the engine running, than when applied with engine -off. The car still would not hold with engine off and put in 1st gear. With the footbrake applied with engine running, and then selecting 1st gear, then switching off - it holds. Surely any decent car should hold a moderate gradient in 1st gear (let alone reverse) with or without foot brake applied. In the interim I have been running around with a half brick in the rear footwell to wedge against the front tyre.! The dealer has initially offered to get the car in and re-adjust the footbrake - but the tightness of footbrakes will reduce over time. Surely I should expect the Merc to hold position whilst in 1st gear or reverse. No other car I have ever owned has had this issue. Has anyone else come across this problem ? Is this a fault with the gearbox or brakes? Other than this worrying issue, the car runs really well. Please advise !!
