Not sure if it's only for the
cupra, but i was told it was for smoother running of the engine . I hear more clunking noise from the dsg when it changes gear at low speed (but thats normal) and also more hiss and more responsive on the throtlle. definately noticed a difference.
I had it done when I had the car in again for that rattling noise...still not solved...going back in again 4th time this thursday...they said the alarm bracket was lose but the noise still came on...then they tried the securing the dails more-still didn't solve noise. THey didn't take dash off and have been taking the car out on loads of runs...done 30 plus miles in the car...ragging it hard to bring out the noise...not sure if i should have the car back in again. although it doesn't harm the car in anyway, it's annoying when it comes on...what do you suggest?
