Description
The Volkswagen/Audi 1.8T 20V AUM engine is a well-regarded turbocharged inline-four engine known for its balance of performance and fuel efficiency, typically producing around 150-180 horsepower depending on the application.
Common issues with the AUM engine include:
1. Oil Sludge: Similar to other 1.8T variants, it can suffer from oil sludge buildup if oil change intervals are not followed.
2. Turbocharger Problems: The turbo may wear out over time, impacting boost and performance.
3. Ignition Coil Failures: These can cause misfires and rough running, particularly in older models.
Maintaining regular service intervals and using high-quality oil can help mitigate these issues. If you’re considering a used vehicle with this engine, ensure it has a comprehensive service history.
