Pump nozzle unit body holder / PDE repair holder for VW, Audi, Seat, Skoda TDI

It affects all diesel engines with pump-injector units (PDE) that are bolted on one side.

- Starting problems with the engine, especially at cold start and when the engine is particularly hot

- Unsteady idling (speed fluctuations) or sporadic misfires at low engine speeds ("choking" of the engine)

- Diluted engine oil ("engine oil build-up") due to diesel mixture (oil level rises over time)

- Missing / low oil pressure if the bearing shells are already worn due to diesel in the oil

- Stalling of the engine in city traffic

- Loss of power

- Loss of compression

Further important information under: "What happens if I do nothing about it and do not install a body holder for the pump/nozzle unit (PDE)?"

- In all diesel engines with pump-injector units (PDE) that are bolted on one side, the PDEs work their way more and more into the cylinder head over time.

- As a result, leaks cause diesel to mix into the engine oil.

- The lubricating effect of the engine oil is significantly reduced, which over time leads to complete engine failure.

Details on the cause of the damage and the functional principle of the PDE bridge can be found in our video:  
Functional principle of the PDE bridge (pump-nozzle bridge) to prevent cylinder head damage

- The PDE bridge has been specially developed for VW 5-cylinder 2.5 liter TDI engines with a pump-injector unit.

- The PDE body holders (PDE repair holders) represent a more universal further development of the PDE bridge, which is suitable for all 3-cylinder, 4-cylinder, 5-cylinder and 10-cylinder VAG/VW TDI engines with a pump-injector unit.

- Customers with a VW 5-cylinder 2.5 liter TDI engine with a pump-injector unit therefore have the choice between the PDE bridge and the PDE body holders (PDE repair holders). Most of these customers opt for the PDE bridge as they have more experience with it.

- The PDE body mount has already been successfully installed more than 1000 times in VAG TDI engines.

- The mileage usually increases by 100,000 km or more.

- Compared to the factory-fitted tensioning shoes, which are only fixed on one side, the PDE body holders ensure that the PDEs are fixed more evenly.

- This means that, especially when the sealing kits are replaced at the same time and the reinforced 07eins-VITON sealing rings, this prevents the PDEs from working their way back into the cylinder head and the familiar problems caused by leaks from occurring. 

Details on the origin of the damage and the functional principle of the PDE body holders can be found in our blog post....

...and in our explanatory video:  
Functional principle of the PDE body holder (pump nozzle body holder) to prevent cylinder head damage

- Our products are installed without any modifications/work on the engine/cylinder head. Original screws and fixing points are used. Service-related reassembly for further maintenance work can be carried out without any problems due to the multi-part design.

- The factory-fitted clamping shoes 2 to 5 for the pump/nozzle units are replaced by the PDE bridge elements.

- Professional inspection and disassembly of the pump-nozzle elements requires the use of new expansion bolts and sealing elements. If required, selected complete sets of consumables of excellent quality are available under the following links:
PDE body holder for 5-cylinder TDI (complete set), PDE body holder for 4-cylinder TDI (complete set), PDE body holder for 3-cylinder TDI (complete set)

- The installation can either be carried out by any garage or you can do it yourself if you have the necessary technical knowledge.

Suitable automotive workshops for installing the 07eins PDE bridge with our installation workshop finder: 07eins Partner workshops

Experienced screwdrivers can also install the 07eins pump-nozzle products themselves.

The corresponding video and PDF installation guides contain all the important information with step-by-step instructions: own installation (do it yourself)

- We always recommend replacing all seal kits of the pump-nozzle units, especially the uses of the 07eins reinforced VITON seals.
