My S3 is due for a service, it's booked in for Friday but I'm unsure whether to get the cambelt done aswell. It's 03 plate with 57k. The service booklet says 115k but thats wrong and was only for pre face lift. BAM engine codes should be 80k. I also heard that audi suggest to change it after 4 years. It's Revo or cambelt! Anyone has cambelts go before 80k?
