Disadvantages of the Audi ALG engine
- Most often, owners complain about lubricant and antifreeze leaks, especially after overheating;
- Bad oil here quickly affects the operation of hydraulic lifters and tensioners;
- The timing belt may not last the prescribed 90 thousand km, and when it breaks, the valves bend;
- At high mileage, an electrician delivers a lot of problems: sensors, coils, lambda;
- The remaining breakdowns are associated with contamination of the crankcase ventilation, throttle and idle valve.
