Hello, My Ignorance!! After I have used the search function, the following question has opened up to me?? The TT is EZ 8/00 has now run 37tkm, I bought it from a VAG or ordered it bindingly. Now the question with the tooth grate, the change is with the Bj. every 5 years or after 180tkm???!!!!. I called the seller today. That are the 5 years in August and what with the tooth grate is!?? He meant just change at 180tkm! He makes me now no ch a new Longlife inspection (30000ér). I have not yet signed the purchase contract! What do you recommend to me what I can do??? Does the dealer guarantee cover such things??? Or should I have the statement of the seller stuck in the purchase contract to get out of trouble later??? Man man there I was glad to have found a TT and then right before you have the car immediately the first setback!!!!
