Anyone tell me what the cam drive is on this engine? Audi web site just says all models with belt drive need changed at 5yrs/ 75K, but don't specify which! Going to look at a 1.4 TFSi for sale this week, but it is almost 5 yrs old and wondered if it is due a belt soon. Big bill in store if so. If chain drive, does it suffer the same problems as Golf 1.4 chain drives? Thanks for any advice.
