Hi first time posting on here hoping someone can help me out. I bought a mk5 GTi 07 3 weeks ago and have noticed that after reading here the car seems to have this cam chain issue. Sounds like a rough diesel with a heavy clicking noise on the left hand side. The dealer has agreed to change it under warranty for me which is a load off my chest to say the least lol. However they rang back and asked had the timing belt been changed and I said yes it was done last year according to the service records and they said good because we need to remove the timing belt to change the cam chain. After plenty of research online and watching YouTube videos I have gathered that this doesn't seem correct lol. My question is basically is there any reason they have asked or would need to do this? And is it possible that there is another chain somewhere near the timing belt in the engine that they have got confused with? Just need to know so I can get back to the dealer so me and him are on the same page lol. Any help is greatly appreciated thanks
