Disadvantages of the Audi AJM engine
This diesel engine’s resource is dependent on the lubricant quality, and it cannot handle low-quality oil;
Hydraulic lifters and camshaft lobes deteriorate due to bad oil;
The turbine’s wedge geometry is typically the cause of the motor’s unstable operation;
Here, the unit-injectors’ single bolt fastening may come loose, causing leaks;
Additionally, the network frequently talks about tandem pump malfunctions.
