Disadvantages of the Audi ALF engine
- These engines are quite reliable, the main problems for owners are leaks.
- If the power unit is allowed to overheat, oil and antifreeze leaks will increase significantly.
- Due to poor lubrication, hydraulic lifters and chain tensioners quickly fail.
- At high mileage, the electrician starts to fail regularly: sensors, coils, lambdas.
- Throttle or idle valve contamination is the main cause of floating engine speeds.
