Passat 1.9 TDI (AVF), Kompatibilität Pumpe-Düse-Elemente | Posts 16+

Good day everyone!

Since the matter is now going to a lawyer, here's a small update:

Using a dental mirror (to be able to see around corners), I re-examined the LEDs that were installed in my device to make sure it was justified to raise such a concern.

The actual installation situation is as follows:

Cylinder 3 and 4:
038130073BA (VW), 0414720216 (BOSCH)

Cylinder 2:
038130079FX (VW), 0986441510 (BOSCH) (Regarding the BOSCH number, I guessed the last two digits without the mirror - but that's irrelevant because the VW number is correct.)

Cylinder 1: 070130073 X (VW, I couldn't clearly see it at first glance without using a mirror...), 41407202XX (BOSCH) (Where I've written an "X", it looks like someone used a soldering iron or something similar to remove the letter (VW) or the last two digits of the part number (BOSCH; it might have been a "11", you can still see a little bit of it).)
This part probably belongs to the 2.5 TDI engine from a Volkswagen Transporter.

Happy Monday!

Regards,

Marc.

You mentioned an AJM nozzle in the first cylinder earlier. Which number is correct then?

You would need the letter that follows the number 070130073 in order to correctly assign it. However, the problem likely remains the same.

Please keep us updated. I would really like to know if and what might come out of this if you involve a lawyer.

Hello, Steffen,

Yes, I know...

Initially, I tried to identify the numbers and thought I had seen them correctly. It's also possible that I simply mixed up the numbers when I wrote them down.

Actually, it's exactly as I wrote in my previous post:

Cylinder 1: 070130073 X, 41407202XX (BOSCH)

As I mentioned: Where I've marked an "X", it appears someone used a soldering iron or something similar to remove the letter after the number (VW) or the last two digits of the part number (BOSCH; it might have been an "11", although it's a bit hard to see).

Therefore, the PDE cannot be precisely identified.

I noticed the issue with the VW number the first time I looked at it, but I thought the "mark" was dirt or oil. However, it can't be wiped off. The distance between the mark and the numbers seemed a bit too large for an additional letter, compared to the other PDE markings. That's why I didn't think much of it... (see above). Image)
It was only when I looked in the mirror that I noticed that the last two digits of the BOSCH part number were obscured in the same way.

Sure, it doesn't change anything, it's just wrong in a different way now...

I'll let you know how things progress – it's going to take forever, as far as I can tell.
I would most likely like to remove the incorrect nozzle. I suppose a qualified expert might need to be consulted beforehand.

Good evening!

Marc.

Okay, so, after some time has passed, here's at least the solution to my PDE question. Unfortunately, I'm still thinking about my ZMS question...

After my inquiries about what exactly had been done to my PDE resulted only in angry outbursts from the workshop, I finally did what I should have done from the beginning during my Christmas vacation:

I once contacted a PDE (Pressure Differential Engine) repair specialist in Hanover who supplied at least one of the two replaced PDE units. Here's what came out:

- The base for the PDE (likely referring to a specific component or system) probably doesn't actually originate from a Passat with the engine code AVF. He probably doesn't have to, though.
- However, the nozzle insert was replaced and fits my engine.
- The company always obscures the original part number on the photo in the way shown.
- The new number is "engraved" on the opposite side (i.e., on the photo on the underside). Unfortunately, even with a dental mirror, it is impossible to detect them when they are embedded.

The workshop was aware of this, but they couldn't imagine that we were constantly talking past each other.

So far, so good.

Oh yes: The engine is still running very smoothly, and the idle speed control is well within the acceptable range.

"Feeling" and based on the sounds, I suspect there's a mechanical problem under the hood – and it's not related to the machine itself, but rather something external to it, as it's been in this condition for quite some time.

Marc.

@Steffen W:

Since you asked:

The performance of the esteemed legal profession has been so utterly terrible so far that I'm genuinely annoyed that I have a deductible in my legal insurance.

- absolutely no technical understanding - well, he's a specialist lawyer, but it would be helpful if he at least had a general idea of what's being discussed.
- Consequently, the discussions are progressing slowly.
- The drafted documents were so bad that I stopped the release process. I spent several hours trying to organize the data and facts and correct absurd misinterpretations.
- However, the lawyer immediately pointed out that, given the answers provided by the workshop, it would likely be impossible to avoid a legal proceeding.

I really think I deserve something for all this effort.

It's unlikely to achieve much: The effort required to prove that the work done by the workshop was unnecessary, that the error analyses were incorrect, etc., is simply disproportionately high.

Sometimes, in the past few weeks, I've thought that it seemed like everyone was somehow expecting this to happen.
Personally, I will have to consider whether it will still be worth the effort in the future, even just to have the "right" in a formal sense. There are more productive ways to spend your time.

What surprises me is the strange sense of self that some people seem to have when they do their jobs. It seems to be working...

Marc.
