A4 TDI 2.0 PD spritzen keinen Kraftstoff ein nach ZK-Tausch | Posts 64+

Sorry, I may have expressed myself incorrectly. The error was not in Cylinder 4 with the walking function, but with the other (new) PDE. Cylinder 3 still showed 299.

Please do all readers a favor and finally write the word Cylinder correctly.

Based on my personal experience, this topic does not lead to any results. Your problems also have nothing to do with "experience," but rather with recognizing and learning from mistakes.

My suggestion would be to hand the vehicle over to a trusted mechanic.

Best regards, Rainer

Well, if he shows this with another, demonstrably intact PDE, then it can't be the PDE. It's really simple and logical. And it's demonstrably intact because it ran without problems in the cylinder before. Isn't that so?

Most importantly, I wrote this to you beforehand. You didn't read or understand it. If it's really just a matter of understanding, then you just need to ask again.

Hello AsceDings!

Even if you, as a self-proclaimed expert, don't have time for counseling others here for a few days - obviously, it doesn't matter

Hey... I don't want to be offensive at all!!!
Have you finally measured the {COMPRESSION} after all?!
No! WHY NOT?? ...again, boredom, lack of Weißbiah, Ritalin deficiency, etc. pp.?!
WHY did you suddenly come up with another alternative, another thing you can break and then fix???!!!
That's really not normal!

Do you know that we are all here at "Dieselschrauber" – some of us professionally, and others (also?) as a hobby?
We are happy to share our knowledge and experience... with newcomers - no topic is off-limits.
And yet, you completely disregard any advice or text, etc. The effort that authors make for YOUR case(!!!) is completely wasted.
WHY?! ...one doesn't really know exactly, but that it IS, at least - now.
And again, continuing:
Customers of the operator will be absolutely given priority, and this will be done with patience and understanding, as if by angels.
But it seems like nothing I do works with you, unfortunately.

The fact is, you either don't seem willing or able to answer our questions about your case in a reasonable and factual manner, and you are also not willing or able to follow up on the advice you have been given.
Too bad. That's a shame!
WHY is it so??
...siehe your post on this page at the very top: No, no, you are not hyperactive or anything - then it must be somewhere else

No worries, I'm not going to write anything more about this, because I'm better off on the couch -still!- playing with marbles. Everyone involved would probably benefit more from this topic than from its further development.
...besides, it's important to be polite to customers and ... hey, I've already been so stressed, trying to keep my bad words under control

Ultimately, YOU, HUU, could solve YOUR problem - not ours! - by carefully reviewing all the posts that have been posted here and working through them step by step!
...and don't touch the {FERVIC} turbo, as I've said before!!!

In this spirit - a toast to Ritalin! ...where in the past a strong slap could suddenly provide immediate (miraculous) healing

Best regards from Munich!

PS: "PDE have been integrated" is NOT a bug description!

Thank you for the previous post, but the fact that I haven't yet measured the compression is because the delivery person hasn't arrived yet and hasn't handed me the new compression test device. I expect him to arrive tomorrow afternoon. Also, I previously wrote that I am only doing one thing and working through the instructions step by step. The Audi is in the garage and waiting. When I say "PDE integrated," I mean that the PDE seats were already installed in the Old ZK, and that installing new seals on the PDE's didn't help either, as I was constantly having diesel in my oil. I had also previously taken the car to a friend's garage and had them inspect it there. They also wanted to charge me a small fortune to replace the ZK. I only paid 80€ for the inspection.

Hello, just a quick update: the compressor tester hasn't arrived yet, unfortunately. I hope it will arrive tomorrow by post so that I can continue.

Hello, I was finally able to test the compression.
Cylinder: 1) 26 Bar
2) 25 Bar
3) 25 Bar
4) 24 Bar

PDE Voltage with ignition ON, 1.66 Volts are present on all 4 connections.

The value in Cylinder 3 had changed briefly when I was warming up the engine before the compression test.

At idle, it smokes slightly. When you give it some gas, a foul, pungent cloud appears. Based on the smell, it smells faintly of unburned diesel.

After a few minutes, the value of Cylinder 3 had changed.

After that, I performed a specific component diagnosis, and the result was as follows.

This error message persists. Is it possible that the PDE cable harness or the rotary connector on the ZK has a defect, or even the control unit? I'm just waiting for your opinion before I do anything.

2 error codes found:
004710 - Valve for Pump/Nozzle Cylinder 3 (N242)
P1266 - 000 - Unplausible Signal - Sporadically

Let's try to understand the compression values first.
While they are uniform, they are not really good. Therefore
- What instrument was used for the measurement?
- Where is it connected (the hole in the light bulb)?
- Were the other light bulbs removed?
- Engine temperature?
- Battery status (some errors in the log could be due to low voltage).

Hello, yes, I was thinking the same thing, but I wanted to hear your opinion first before proceeding. I was so wrong:
Engine temperature 76°
Plug on the ZK for PDEs, unplugged
Take all the light bulbs out
Adapter screwed into the candle holder.
Device connected
All components checked for secure fit and airtightness.
Motor started approximately 5 seconds ago.

In my car's scan, the error message appears multiple times,
Undervoltage lower limit threshold breached, Ambient conditions: Voltage 9.30V

PKW Diesel Compression Tester Compression Tester TDI CDI Pressure Tester Test Device

Hello Herbert, I think your assumption is correct. The starter from the accessories, battery charge too low, See Auto Scan. After the engine was assembled and the first start attempt was made, the required starter RPM was not reached, I then bridged it with another vehicle, even then it only reached 233 RPM and started with a few misfires. Therefore, I am assuming the battery voltage. In the car, the scan only shows 9.30 volts.

Should I perform a re-compression test this time, using a new battery or a bypass, ????

Hello ascendens,
my question was, what instrument was used, i.e. manufacturer and type. Now I only know that you bought a treasure chest on eBay.
Does it at least have a backflow valve, meaning does it maintain the measured pressure until you release it?

Yes, I know, this shipping company, that's where I bought the first measuring device two weeks ago, but unfortunately it didn't work. Then I bought this one, and it works really well, and it also maintains a constant pressure in the pressure line. It has a backflow valve, but I don't know exactly how it works. The device is a generic brand. I also looked at professional-grade equipment, but they were really too expensive, costing between 400 and 500€. There is a German instruction manual included, which states that the device is very precise and that it is important to avoid leaks during use.

As I said, a treasure chest. How well it works is a matter of debate. For the price, it can't be manufactured properly in East Asia.
Please perform the next measurement with a fully charged battery, and continue activating the starter until the pressure no longer increases.
