Podcast #3: PDE body mount, PDE bridge, and the new 16V PDE bridge explained.
Simon Schoßböck, Managing Director of 07eins GmbH and the original inventor of the 07eins PDE solutions, explains the well-known pump-nozzle issue—and demonstrates why even 16V 2.0-liter TDI engines with double-bolted Bosch PDEs may require additional stabilization.
The Problem
The damage often begins before you notice it.
Many pump-nozzle TDI engines still run without issue in everyday use, even though a critical process may already be starting in the cylinder head. The pump-nozzle elements are subjected to heavy stress during operation. Over many kilometers, they can shift slightly, tilt, or wear into the cylinder head.
If this compromises the seal, diesel can leak into the engine oil. The oil loses its lubricating properties, bearing points are subjected to greater stress, and in the worst case, severe engine damage is a risk. This is exactly why the PDE issue is so important for TDI drivers.
A TDI may still run—even as a critical process is already beginning inside the engine.
The 07eins Solution
From the PDE body mount to the 16V PDE bridge.
The original 07eins PDE body mounts were developed because the classic PDE bridge cannot be used on every common-rail engine. Especially in many 3- and 4-cylinder engines, the installation space under the valve cover is limited.
The PDE body mount therefore specifically stabilizes the individual PDE body. The new 16V PDE bridge consistently extends this principle—for 16V 2.0-liter TDI engines with double-bolted Bosch pump-nozzle elements.
- PDE body mount for many 3-, 4-, 5-, and 10-cylinder PDE TDI engines.
- 16V PDE bridge for compatible 16V 2.0-liter TDI engines with double-bolted Bosch PDEs.
- Designed to provide additional stabilization for the pump-nozzle elements.
- Designed for less Smoother operation, fewer scoring marks, and better protection for the cylinder head.
Original 07eins
Simon Schoßböck: original inventor of the 07eins PDE solutions.
The PDE bridge, the PDE body mounts, and the new 16V PDE bridge are not random accessories. They are technical solutions that arose from a real engine problem. Simon Schoßböck, Managing Director of 07eins GmbH, developed the original 07eins solutions for the pump-nozzle problem based on his own experience, technical analysis, and continuous development.
The products follow the same basic principle: stabilize pump-nozzle elements, reduce movement, protect cylinder heads, and ensure the long-term preservation of TDI engines.
Simply explained
How does diesel get into the engine oil?
The PDE moves minimally. Due to high forces during operation, the pump-nozzle assembly can tilt or shift over time.
The cylinder head develops wear marks. The sealing surfaces are stressed, and the seal can gradually deteriorate.
Diesel can enter the engine oil. Particularly insidious: The driver often notices little of this at first, while the oil is already being diluted.
Lubricity decreases. If the engine oil is diluted by diesel, bearings, the camshaft, and other components can suffer severe damage.
Latest 07eins PDE solution
:The 16V-PDE bridge for 16V 2.0-liter TDI engines.
Starting at minute 15:00, the podcast discusses the latest PDE development from 07eins: the 16V PDE bridge for 16V 2.0-liter TDI engines with double-bolted Bosch pump-nozzle units.
This solution was developed relatively late because double-bolted PDEs appear more stable at first glance. The obvious assumption was: If the PDE is already secured with two bolts, the movement should be sufficiently controlled.
However, practice showed a different picture. Even
PDE
can operate under operational forces, leverage, and minimal movement in the cylinder head. This can lead to wear marks, even though the design initially appears more secure.
- For compatible 16V 2.0-liter TDI engines with double-bolted Bosch PDE units.
- Developed because even double-bolted PDE units can operate under load.
- Reduces unwanted movement and further stabilizes the PDEs.
- Not intended for Siemens pump-nozzle units.
Bridge, body mount, or 16V bridge?
Three 07eins solutions. One goal: to stabilize PDEs.
Original 07eins PDE bridge Particularly well-known for the 2.5 TDI. It replaces the original mounting setup with a continuous bridge structure.
Original 07eins PDE body mount More versatile for use with many PDE TDI engines where a classic bridge structure is not possible or not practical.
Original 07eins 16V PDE Bridge Designed for compatible 16V 2.0-liter TDI engines with double-bolted Bosch PDEs, where movement and wear marks can still occur.
Common Principle All solutions pursue the same goal: to stabilize the pump-nozzle assemblies, protect the cylinder head, and prevent consequential damage.
For families, campers, and everyday drivers
When the TDI is more than just a car.
Many TDI drivers use their vehicles for more than just a hobby. They are family cars, tow vehicles, campers, vans, or everyday cars. That is exactly why the PDE issue is so serious: If a vehicle breaks down during a long trip, on vacation, or in everyday use due to diesel entering the oil or cylinder head damage, it quickly becomes expensive.
A well-thought-out technical preventative solution can therefore be worthwhile if the vehicle is to be maintained in the long term.
Repair instead of discarding
Preserving value is also sustainability.
Many older TDI vehicles still have high utility value. Instead of prematurely writing off vehicles, 07eins relies on technical repair and preventive solutions that extend the service life of existing engines.
This makes economic sense and also helps preserve value. When a vehicle can be maintained in a technically sound manner, a precisely engineered solution is often the better answer than a hasty replacement.
Do you drive a common-rail TDI?
Whether it’s a common-rail bridge, common-rail body mount, or a new 16V common-rail bridge: The original 07eins solutions were developed to secure common-rail components more securely, protect the cylinder head, and make TDI engines more reliable in the long term.
