Pinking?
I have a 2011 C250 diesel Estate and when I accelerate, the engine makes a jingling (pinking) sound which stops as soon as I ease off the gas. My garage says that this is perfectly normal, but is that correct? The car is also hesitant for the first 100 yards, but then seems to surge as if the turbo has just kicked in. Does anyone else find the seats in these cars uncomfortable on long journeys? Thanks in advance.
