Hi can any one shed some light on this problem I’m getting with my 2015 Diesel A220. It went in to the main Dealers for a “A “service with no problems at all, but ever since I have had it back there is a knocking noise when coasting from 40mph and slower.
I have watched what gear the car is in and it’s in D5 when’s it’s doing 20mph as soon as the car changes down a gear it stops which indicates to me that the car is labouring, Mercedes main dear have charge me £100 pound to plug laptop in to see what’s going on and they can’t find anything. So they told me they have just updated the software hopefully that should sort it out, but it’s now worse
