Theres a guy near us (Leeds/Wakefield) that can change the mileage, he has a cable that plugs directly into the clocks, Thai's right, you cant do it through Vag-com or Vag-Tacho.The guy near us charges £40
I always thought yours was the 8v Sharki. Can defo confirm though that Vag Tacho will not work on the Mark 3 as Brad will remember from my old Golf
40 mine were to doleeds based, clocks need to be out the car and it takes minutes to do
