Hi, I've had one of the fog light grilles nicked from my A4 1.8T SE & am finding out why. I can't find anywhere to get another one. The model description is 8E2 OAH A4 limousine 1.8 R4 I did get hold of a pair of B6 grilles but they are too small. there's plenty of B6 grilles but no R4. Any suggestions if R4 not available (can't understand why) then is there something which will fit?
