Not sure if many have mate. But if I were you, phone Audi UK customer service and play dumb! Just say you have heard of many recalls on the 2.0tdi for injector replacement, do not mention you have a 140.
Just give them your reg and they will either say yes or no.
The problem really seemed to be on the 170 models roughly around 2006/2007.
Whatever you do, do not call your Audi dealer, speak direct to Audi UK as dealerships, although known to them, they also play dumb as they do not want to pay the expense. It is actually Audi UK that pay for the work to be done.
