Disadvantages of the VW AXE engine
Leaks from the tandem pump and nozzle seals are the primary issues;
Another sleeveless aluminum block is prone to scuffing and is terrified of bad diesel fuel;
This is where the oil system heat exchanger frequently leaks, allowing lubricant to get into the antifreeze;
Rockers or camshaft cams may already be worn out after 200,000 kilometers of operation;
Although there are still many flaws in this unit, they are common to contemporary diesel engines.
