I would just like to add my experience for others to be aware.
my Audi A3 1.6 was always serviced and had no problems and had just had a MOT
had the EA189 modification done by Audi dealer as I didn't know I could refuse. Oh I wish I knew that I could have
not only did they tell me my MOT was due but a list of things to do but didn't really need doing. It didn't really drive as well home but expected some changes but not the light to come on and go into limp mode.
Has needed work done on the engine and back in today as it still isn't driving without shuddering and the fan comes on?
I have sent an email to Audi but don't expect any joy and Cardiff Audi well still waiting for their call back
