Disadvantages of the VW AEX engine
Although this power unit is easy to use and dependable, maintaining it is not very convenient.
Oil leaks from beneath the valve covers are the most well-known engine issue.
The valves always bend when the timing belt breaks, which is a well-known unstable resource.
Floating idle is typically caused by throttle fouling.
Owners must deal with rings and oil burners on long runs.
