Disadvantages of the Audi AAE engine
- The main problems for owners are caused by malfunctions in the Mono-Motronic system;
- The reason for unstable operation is most often air leakage or sensor failure;
- In second place in frequency is the failure of the components of the ignition system;
- The timing belt lasts about 90,000 km, but when it breaks, the valves usually do not bend;
- On long runs, an oil burner and knocking hydraulic lifters are often found.
