Retrofitting PDE body mounts - permanently eliminating leaks in TDI engines
TDI engine and leaking PDEs? Many drivers of Volkswagen diesel engines are familiar with the problem: despite correct installation, the engine starts to leak, starts poorly or loses power. The cause usually lies in an invisible detail - the moving pump-nozzle elements (PDEs).
We explain the cause and solution in detail using models in this video:
Why do PDEs leak?
With many 1.9 TDI, 2.0 TDI and 2.5 TDI engines the PDEs are only fixed in place with a bracket as standard. What many people don't know: The PDEs move minimally under loadwhich can lead to a leak in the cylinder head. The result: diesel escapes, the engine runs unevenly or, in the worst case, is severely damaged.
✅ The solution: retrofit PDE body holder
The PDE body holder completely encloses the pump-nozzle element and prevents any movement - even with high performance or tuned TDI engines. This ensures maximum stability and permanent tightness.
Advantages of the PDE body holder at a glance:
-
✅ Protects against cylinder head damage due to leaks
-
✅ Prevents PDE movement under load
-
✅ Increases the service life of the engine
-
✅ Ideal for chip tuning, boost pressure increase and everyday operation
-
✅ Can be retrofitted quickly and without modification
For which TDI engines is the PDE body mount suitable?
The body holders are ideal for all pump-injector TDI engines from the VW Group (Volkswagen, Audi, Skoda, Seat) such as:
-
VW T4 2.5 TDI (e.g. ACV, AJT, AXG, AHY)
-
VW T5 2.5 TDI (e.g. BNZ, BPC, AXD, AXE)
-
Audi A4/A6 1.9/2.0/2.5 TDI
-
and many other models with PDE technology from 1998 to 2010
Conclusion: Rescue TDI - with PDE body holder
If you have your TDI engine reliably and maintain it in the long term the PDE body mount is the right choice. Whether for everyday use, in a motorhome or on the racetrack - this simple retrofit provides effective protection against damage and extends the service life of your engine.
