The ORIGINAL 07eins Solution for PDE problems in VW, Audi, Skoda and SEAT TDI engines

The well-known PDE problem - causes, symptoms and the permanently safe solution

Developed for all TDI engines with a PDE system - including the VW T5 as the most common application

Many VW, Audi, Skoda and SEAST TDI engines with pump-nozzle injectors (1.9, 2.0 and 2.5 TDI) built between 1998 and 2010 are affected by leaks in the pump-nozzle elements (PDE) due to their design. This leads to typical symptoms such as starting difficulties, jerking, loss of power or rising oil levels. The problem is particularly common in the VW T5; however, it actually affects numerous other TDI models.
The ORIGINAL 07eins PDEbridge and the patented PDE body holder ensure that the PDE element is stabilized, no longer tilts and the engine remains permanently tight. This reliably prevents expensive consequential damage such as cylinder head replacement or engine damage.

Why many VW, Audi, Skoda and SEAT TDI engines are affected by the PDE problem

Typical symptoms, causes and risks of a leaking PDE element

Many VW, Audi, Skoda and SEAT diesel engines with a pump-injector system (1.9, 2.0 and 2.5 TDI) sooner or later suffer from the same design problem: the PDE element is not sufficiently stabilized in the cylinder head. Due to material wear and the one-sided support, the element begins to tilt - a leak develops.
Typical symptoms are starting problems, uneven engine running, jerking after a few minutes of driving, loss of power or a constantly rising oil level. In many cases, diesel gets into the engine oil, which reduces lubricity and can cause further damage to the turbocharger, bearings or, in extreme cases, complete engine damage.
The problem not only affects popular models such as the VW T5, but also numerous TDI vehicles built between 1998 and 2010. The engine technology affected is identical and therefore also the cause of the damage

Many symptoms are mistakenly attributed to the turbocharger

Why typical "turbocharger problems" often turn out to be PDE leaks

Many drivers assume that the problem is caused by juddering, loss of power, black smoke or a suddenly rising oil level initially indicate a defect in the turbocharger. In many cases, however, it is not actually turbocharger damage, but a leak in the pump-nozzle unit (PDE).
As the PDE element in the TDI cylinder head is only supported on one side due to its design, it can tilt over time. This leads to diesel getting into the engine oil or the combustion pressure no longer building up properly - symptoms that are often mistaken for a defective turbocharger.
A correct diagnosis is crucial: while a new turbocharger incurs high costs and often does not solve the actual problem, stabilizing the PDE element permanently eliminates the cause.

Preventing PDE damage - before expensive problems arise

Why it makes sense to stabilize the PDE system at an early stage

Even if your TDI engine is currently running smoothly, the PDE problem is inherent in its design. Due to the one-sided support, the PDE element can tilt over time and cause a leak. Many consequential damages - such as rising oil level, loss of power or diesel in the engine oil - develop gradually and are only noticed when considerable wear has already occurred.
Early stabilization of the PDE element using the ORIGINAL {{5c8790f6502e15eaeb3e036d65ef31e7} PDE bridge or the PDE body holder prevents precisely this process. The components ensure a stable fit of the PDE element, reduce material wear and avoid expensive repairs such as cylinder head replacement or engine damage.
A preventive solution is therefore particularly recommended for drivers who want to maintain their TDI in the long term

Is the engine jerking, stalling or losing power? How to recognize a PDE problem

Typical symptoms and why they are often misinterpreted

Many drivers notice the first signs of a PDE problem without immediately recognizing the cause. After a few minutes of driving, they often experience jerking, uneven engine running, loss of power or the engine occasionally stalling. Starting difficulties or a noticeable development of smoke can also be indications.
These symptoms often resemble a defective turbocharger, a fuel problem or worn sensors. In practice, however, it is often the case that the cause lies in the PDE system: If the PDE element tilts or leaks, the combustion pressure no longer enters the combustion chamber correctly - the engine noticeably loses stability and power.
Early diagnosis and stabilization of the PDE element prevents minor symptoms from turning into expensive damage. Die 07eins PDE bridge and the PDE body holder fix the cause directly and ensure that the engine runs smoothly and reliably again.

Oil level rising or diesel mixing into the engine oil? There is now a risk of serious engine damage

Why a leaking pump-nozzle unit leads to massive consequential damage

If the oil level rises or a smell of fuel can be detected in the engine oil, there is usually an acute leak in the PDE system. As the PDE element tilts, diesel enters the engine oil, causing a rapid reduction in lubricity. This results in considerable damage to the bearings, rocker arm shaft, cylinder head or - in the worst case - complete engine damage.
Many drivers suspect a defective turbocharger or a damaged fuel system in this situation. However, in the majority of cases it is actually a PDE problem that does not resolve itself and gets worse with every journey.
The ORIGINAL 07eins PDE bridge (for 5-cylinder TDI engines) and the PDE body holder (for all engine variants in which no bridge can be fitted) immediately stabilize the PDE element and restore tightness. This can prevent expensive repairs such as a cylinder head replacement or a complete engine replacement.

The permanent solution for PDE problems: ORIGINAL 07eins PDE bridge and PDE body holder

Stable fixation for all TDI engines - suitable for 1.9, 2.0 and 2.5 TDI with PDE system

The ORIGINAL 07eins PDE bridge and the PDE body holder were developed to permanently solve the design problem of the pump-injector unit in many VW, Audi, Skoda and SEAT TDI engines.
The PDE bridge is used in 5-cylinder engines (e.g. 2.5 TDI): A high-quality, torsionally rigid construction that stabilizes the PDE element and prevents it from tilting or leaking. The bridge provides additional support, which the cylinder head does not offer by design - and thus reliably restores tightness in the combustion chamber.
For engine variants where the bridge cannot be fitted due to the design (e.g. 1.9 or 2.0 TDI), the PDE body holder is used. This fulfills the same function, can be installed flexibly and is also made from high-quality materials.
Both solutions are available as sets with VITON gaskets and installation material and replace the cost-intensive cylinder head replacement with a technically superior, sustainable repair solution

Cylinder head replacement or PDE solution? The direct cost comparison

Saving the engine instead of replacing it - how much you can really save

A leaking PDE element is often repaired with a complete cylinder head replacement. However, this repair incurs very high costs of around 2,500 to 5,000 euros and does not permanently resolve the actual design problem. As the PDE elements are still held on one side, the leak can reoccur at any time.
The ORIGINAL 07eins PDE bridge and the PDE body holder come into play here: They permanently stabilize the PDE element and prevent it from tipping again or diesel getting into the engine oil. Depending on the set, the costs are between around 400 and 900 euros and include high-quality materials, installation kits and optional VITON seals.
As a result, the PDE solution offers a technically sustainable and at the same time economically much more favorable alternative that protects the engine and avoids high follow-up costs

Frequently asked questions about the PDE problem and the right solution

For which TDI engines are the PDE bridge and the PDE body mount suitable?

The ORIGINAL 07eins PDE bridge is suitable for all 5-cylinder TDI engines in which the PDE element can be supported laterally due to the design - typically 2.5 TDI engines, such as those installed in the VW T5.
The PDE body holder was developed to also cover engine variants without the option of bridge mounting, for example many 1.9 TDI and 2.0 TDI units. Both solutions permanently stabilize the PDE element and prevent it from tilting or leaking again.
The 07eins products cover a large proportion of VW and Audi TDI engines with a pump-injector system. Which solution is suitable for your vehicle depends on the engine variant and the cylinder head design.

How can I tell if a pump-nozzle element is defective?

Typical symptoms of a defective PDE element are jerking, uneven engine running, loss of power, starting problems or an increasing amount of oil. These signs occur when the PDE element in the cylinder head no longer seals and diesel gets into the engine oil or the combustion pressure is no longer built up properly.

What is a PDE body retainer and when is it used?

The PDE body holder is a component that stabilizes the PDE element if a PDE bridge cannot be fitted due to the design - for example in many 1.9 or 2.0 TDI engines. It fulfills the same function as the bridge and reliably prevents the element from tilting.

Which repair kit is recommended for leaking PDE elements?

For a complete and lasting repair, 07eins recommends a PDE installation kit and additionally the reinforced, high-quality 07eins VITON gaskets, as these are more temperature-resistant and durable than standard gaskets. In combination with a bridge or body holder, the PDE system can be permanently sealed.

Can a turbocharger be defective even though the PDE element is actually to blame?

Yes. Many symptoms of a supposedly defective turbocharger - such as loss of power, smoke development or poor acceleration - are actually caused by a leaking pump-nozzle unit. An accurate diagnosis prevents unnecessary costs for a new turbocharger.

How do I set a pump-nozzle element correctly?

The correct setting is made via the position of the PDE element and the contact pressure of the rocker arm. This should only be done in accordance with the manufacturer's instructions and with a suitable tool. Incorrect adjustment can cause damage to the rocker arm shaft, camshaft or PDE element.

Is an engine repair necessary if the PDE element is leaking?

Only in severe cases. In most cases, an engine repair can be avoided if the PDE element is stabilized and sealed in good time. Die 07eins PDE bridge and the PDE body holder prevent the problem from recurring.
