Hello My name isXXXXX will be glad to assist you today in answering your questions.
Has the engine ever been over heated for any period of time, if so the cam gears can warp, and wobble causing the belt to want to slide off. These belts tend to want to ride to the outside of the cam gear to start with, so if the gear is warped in any way it will just push the belt right off.
Alright. I bought this car in this condition. it does run fine. but i know this is not correct i am a mechanic myself. do not have alot of experience with audis. as far as it ever over heating im not sure.it hasnt since ive had it. when you say gears you mean the pulleys or the cam or crank? need more.
everything is new except for gears. tension, bolts are torqued and set by book specs. so... if i replaced all gears. this would without a doubt do it?
