Hello all, according to checkbook must be changed at my A4 1.8; 92 KW, Mj 2000, motor ARG of the timing belts only at 180,000 km. That seems quite late. Does the ball bearing of the tensioning roller last so long? How did you behave? Has someone ever had problems with the timing belt at the 92 KW machine? What does the timing belt change cost ? Tips ? Greeting Frank
