Twice after service my 08 C Class gearbox has had changed characteristics: changing up later and down earlier with an increase in diesel consumption. Car also seems noisier – but this could be due to higher revs.
At first service it was returned to main dealer garage and fixed by "adjusting electronic settings". Second annual service at main dealer caused no problems. After recent third service a similar situation was created but when returned to M-B specialist who carried out this service they could identify no problems on their M-B diagnostic machine.
Is this common and what is the fix?
