My 2012 C63 Saloon has 61k miles....people know I bought the car in July this year. I had some worries over the gearbox and a jerkiness to it. Long story short, it went into Mercedes of Warrington and they changed a number of gaskets on the car as it had a number of oil leaks and the ATF was changed. Bill came to £2500...thankfully the dealership I bought the car covered the bill. When I collected the car, apparently it had been test driven and everything 'appeared fine'.
Literally a day after collecting the car after Mercedes had the car for a month (yes I know) I came down with Covid and the car was sat for two weeks. However, Iv covered approximately 500 miles since collecting the car and something still isnt right. When the car is cold and getting to temperature, all seems fine and changes are smooth. However, once the car is warm and has been running for a while, the stutter becomes more noticeable especially from 1st to 2nd in Sport or 2nd to 3rd in Comfort. For example, driving at low speeds around a car park or pulling out of a side road, the car sometimes jerks back and too as if it doesnt know what gear it ought to be in. If you are really easy on the gas, all seems ok but any sort of force on the accelerator then it will surge, the revs build until it settles in the correct gear.
Iv also noticed a bit of a grinding noise if I pull out of a side road with the steering wheel turned and the surge back and forth when you press the accelerator. If you floor the car then all is well.
Another point to add, when I am driving nice and easily and look at the rev counter, the needle bounces ever so slightly and its not super smooth.
Im booking the car into a well respected Independent in Warrington to get them to give the car a once over. Its taking away any real fun with the car at the moment as I know something isn't quite right. Could this be diff related? Could the brakes be binding as when I brake you can hear a grumbling noise?
