Disadvantages, breakdowns and problems of the AAS internal combustion engine
This is a very reliable and durable diesel engine without a turbine and with a mechanical injection pump.
The only weak point of the motor is the cylinder head prone to cracking
You also need to monitor the condition of the timing belt, since the valve bends with a break
After 200 km, lubricant consumption is common, up to a liter per 000 km
Even on long runs, the high-pressure fuel pump often flows here due to the wear of its gaskets
