Disadvantages of the Audi ALT engine
To begin with, this engine is renowned for its remarkable oil consumption.
The low resource of the chain tensioner, which doubles as a phase regulator, comes in second.
Air leaks are caused by frequent cracks in the crankcase ventilation pipes.
Additionally, the lubricant pressure sensor and oil pump are not very sturdy.
Modern hollow exhaust valves frequently burst here at high mileage.
