Nozzle Tester: Is It Worth the Investment?

Hello.

What do you think about this?

Is this an original Bosch part that is also suitable for TDI injectors?

Considering the price of a set of injectors, it might actually pay off in some cases. If you're having engine problems, being able to rule out the injectors as the cause can be worthwhile, rather than just buying a new set of injectors based on suspicion alone.

Of course, only if you don't know of a reliable workshop that you can trust.

Hi diesel.gustav,

We could have met up then.

I think you might want a PD (presumably referring to a specific type of document or certification). However, if you do, you'll likely encounter real problems with the testing equipment.

I agree with diesel.gustav's opinion: decent VP TDI injectors and suitable testing equipment (including assessment of the second opening stage) are simply too expensive for home use.

Hi Bertil.

It's not time for that yet... and even if it were, I would probably decide not to sell my VP car, but rather put it in storage and continue driving it later on, if the PD (presumably a different car) turned out to be a disappointment within the first few years.

Is there a device that's roughly comparable and can be used to test PD elements?

Forget it: In cases where individual pressure sensor elements malfunction, a diagnostic check of the control unit is required. This pains me, as I mentioned in another post before, but that's just how it is. A PD element cannot be tested with a nozzle test stand because you need a drive to generate the high pressure. As far as I know, there is currently no testing equipment available for field service that can perform such tests.

Hello Gustav.

With the diagnosis, it is only possible to assess the needle movement in Parkinson's disease, as far as I know.

So, with high mileage and vague symptoms that might resemble injector wear, does it ultimately come down to replacing the injectors, which aren't exactly cheap, even if there's no concrete evidence of a problem?
