DPF light

[Fish99]

Hi guys, im doing really well with my B6 2.0 170 at the mo. I have only had it 3 days , and in that time the rear parking sensors have packed up and the fuel economy is poo, even my old Mitsubishi Evo wasnt as bad.

Anyway, tonight i have the diesel particulate filter light on with the text message also. I have a 3 month warranty on the car from the dealers so is this a job which warrants taking it back to them?. would this filter be responsible for poor economy also?

obviously i want a proper fix on the car and not some temporary measure in which i will be liable for once the warranty has expired.

any advice would be appreciated

Thanks

Neil
