Audi A3, 2007 MY 170bhp......Had stutter when cold between 1500 to 2500 rpm, before Injector Recall. Booked the car in, for the recall to have injectors replaced before looking into the stutter, hopeful this may actually be the cause. Collected the car, drove up the road and still the stutter - excellent road test that must have been.
So, having looked into some of the various potential causes of the stutter I replaced the fuel filter and hey presto, no more stutter. However, 3-4 weeks later I have now had the DPF Light come on. As I do 90 Motorway miles each working day this soon cleared. But I phoned Audi Uk Customer Services highlighting this and stated if I believed a fault was caused through the replacement of the injectors I would hold them liable for all costs. They have promptly called, whilst not admitting liability they have said because I have raised this, then if a fault develops to speak to my local dealer. The local dealer has been told to call Audi Uk to then discuss the fault.
The next day, you guessed it the DPF came on again. Another trip to work and the DPF light has gone out. So, will in due course see how this goes and post back on results of dealing with Audi Uk Customer Services and Local Dealer.
