Disadvantages of the Audi ALT engine
- First of all, this engine is known for its impressive oil consumption.
- In second place is the low resource of the chain tensioner, which is also the phase regulator.
- The crankcase ventilation pipes regularly crack, which leads to air leakage.
- Also, the oil pump and the lubricant pressure sensor are not very durable.
- At high mileage, newfangled hollow exhaust valves often burst here.
