VW/Audi 2.5 R5 TDI PD Engine Problems & Reliability

These 2.5-liter TDI PD engines are less robust than the older version. It is, however, an excellent engine and highly durable if you perform the maintenance properly (400-500k unaffected miles).

However, certain people have had cylinder head and camshaft issues, usually due to applying the incorrect oil.

Specific engines had rubber seals wear out slots inside the fuel chambers around the injector, releasing diesel fuel into the oil and causing a pressure drop.


AXD – 131 hp (96 kW) at 3500rpm, 250 lb-ft (340 Nm) at 1900 rpm. This engine fits into VW Transporter 2004.

BAC – this engine has the same specs as AXE but it is designed for VW Touareg – longitudinal mounting.

AXE – 174 hp (128 kW) at 3500rpm, 295 lb-ft (400 Nm) at 1900 rpm. This engine fits into VW Transporter 2004+

When did they stop making PD engines?

Most manufacturers stopped producing non-DPF vehicles in the middle of the summer of 2010. Therefore, any cars registered in December after the fact could have been considered older stock. We owned one of those mid ’90s, early 1.9 90PS TDis on the Golf.
