Disadvantages of the Audi ALG engine
Owners most frequently report lubricant and antifreeze leaks, particularly following overheating; poor oil here rapidly impairs the performance of hydraulic tensioners and lifters;
The valves bend when the timing belt breaks because it might not last the required 90,000 kilometers;
An electrician delivers many issues at high mileage, including sensors, coils, and lambda;
The crankcase ventilation, throttle, and idle valve contamination is linked to the remaining malfunctions.
