Frequently asked questions about the PDE bridge (FAQs)

It affects all diesel engines with pump-injector units (PDE) that are bolted on one side (model years 1998 to 2010).

- Starting problems with the engine, especially during cold starts and when the engine is particularly hot

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

- Diluted engine oil ("engine oil increase") due to diesel mixture (oil level increases over time)

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

- Stalling of the engine in city traffic

- Power loss

- Compression loss

Further important information under: "What happens if I do nothing about it and do not install a bridge 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 the course of the running time.

- This causes diesel to be mixed into the engine oil due to leaks.

- The lubricating effect of the engine oil is significantly reduced, which in the course of time leads to complete engine damage.

Details on the origin 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 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 mounts. Most of these customers opt for the PDE bridge as they have more experience with it.

- The PDE bridge has already been successfully installed more than 10,000 times in VW 2.5 liter TDI engines.

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

• Die PDE-Brücke sorgt im Vergleich zu den werkseitig montierten Spannschuhen, die nur einseitig befestigt sind, zu einer gleichmäßigeren Fixierung der PDEs.

• Dadurch wird, insbesondere bei gleichzeitigem Erneuerung der Dichtsätze und Verwendung der verstärkten 07eins-VITON-Dichtringe, vermieden, dass sich die PDE in den Zylinderkopf wieder einarbeiten können und die bekannten Probleme aufgrund von Undichtigkeiten auftreten.

- Our products are installed without 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.

- The professional revision 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 at the following link:

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

Geeignete KFZ-Werkstätten für den Einbau der 07eins PDE-Brücke finden Sie bequem mit unserem Einbau-Werkstätten-Finder:07eins Partnerwerkstätten

Geübte Schrauber können sich auch selbst an den Einbau der 07eins Pumpe-Düse-Produkte wagen.
