    Default 1.9 Caddy injectors

    I have friend that is driving a 2010 1.9 diesel VW caddy. Now he have been struggling for the past 3 years to get it to run properly. The caddy would just cut out. After old fasianed fault finding the diesel pump was the culprit. The diagnostics didn't find anything wrong. Currently he is experiencing problems with the injectors.

    Can anyone recommend a company or person that sell decent priced injecors?

    decent priced injectors is really hard to find. But you can get northern diesel in pretoria to redo them. i am assuming it is 1.9 PD motor?.

    PD refers to Pumpe-deuse.

    I found this description on the TDi Club forum:

    "Other VW TDI models with the 1.9 litre 4-cylinder of 115 hp or 150 hp, and the 1.2 litre and 1.4 litre 3-cylinder engines, use a so-called "pumpe-deuse" (German) or "pump-nozzle" (English translation) system. In these engines, each cylinder has its own small high-pressure fuel pump which is actuated by the same camshaft that operates the intake and exhaust valves. Fuel is delivered to each pump-nozzle by a low-pressure pump serving the same function as the internal vane pump in the distributor-type system. As the engine cylinder approaches the end of the compression stroke, the main pump plunger advances, pressurizing the fuel. A solenoid valve adjacent to each pump-nozzle is normally open and bypasses the fuel. When the solenoid valve is energized, the bypass passage is closed and the fuel is forced to an extremely high pressure and through the injection nozzle. At the end of the required injection period, the solenoid valve de-energizes and any remaining fuel pumped by the plunger bypasses the nozzle. Thus, fuel is injected as long as the solenoid is energized, allowing full control of injection timing and duration. This system has the significant advantage of eliminating the separate high-pressure fuel lines from the pump to the nozzle because it is all built into a single unit, thus giving better control of the injection cycle."

    Jip!
    Fantastic system, which could not make emission legislation, though!

    In my opinion also more durable than common rail systems. We have a fleet of Volvo EME`s Fitted with the older generation PD engines. Some of them currently between 25 000 and 30 000 hours. Engines unopened ,and on all of them bar 1 still the original injectors. The one which was the exception, only 1 injector replaced. On the other hand we also have a fleet of Merc trucks with common rail systems. Replacing injectors on them almost as regular as oil filters.
