Hope you have better luck with yours than I have, just got to 1300 miles and all of a sudden the car was struggling to pull away.
Pulled out of a junction on a 60mph road and the car just stopped, eventually got it to move and then had to call Mecedes assist.
Thought originally it was just the master brake cylinder that had failed, but ended up being a lot more complicated than that.
Ended up that engine oil had gone up through the braking systerm due to a faulty valve, they had the car in the dealership longer than I owned the car, and now I've got it back there's is a definite lack of power.
I'm in the process with Mecedes in trying to get a replacement car, I don't want my money back as I like the car but just want a replacement!
