Not so much what I did but I had it in the dealers for a slight knock when in reverse. The master technician could here it but could not locate. They referred it to vw technical. They advised that the technician was not to touch it as vw have had a fair few of these complaints and there is a technical bulletin due in the next 5 weeks to advise all dealerships as to how to sort it.
They amended my service schedule to yearly as they had put it on a long service defying the purpose of buying the service pack. Lastly, I asked them to look at my mpg as it was lower than I expected so I asked that they investigate and look at the DPF. No issue and technician advised that it was fine as the long term reading was at 44mpg. This however is inaccurate as it inudes both motorway and city driving. I only enquiry about why the city return was poor.
