Hello,

It turned out that all 5 Power Distribution Units (PDUs) in my T5 had an electrical defect (BIP signal).

Five brand new nozzles, directly from Bosch, arrived at the bus depot today. After the installation, I wanted to enter the injector parameters into the engine control unit.

To my knowledge, this should work with a login to unlock the customization options in the engine control unit. In another thread, it was mentioned that channels 71 and above were used for adjustment, but this was for an Audi A4.

The channels, however, are not available to me. I then searched all the channels up to 150, but unfortunately, without success.

Can someone tell me how to update the 5-digit value in the engine control unit (ECU) of a T5 manufactured in December 2005 with an AXD engine?

Hi Andreas!

The AXD is a PD motor in which... W. does not need to be trained on PDEs, unlike the CR motor.

It is important that the same generation of PDE (Pressure Drop Element) components are used again!

Regarding your story about having 5 defective PDUs at the same time, I find that hard to believe...
Have you previously created a log for the MWB models 13/18/23, and can you upload it here?

Best regards from Passau!

[Translating...]

Es wurden Düsen mit einer anderen Nummer verwendet (statt 0414720210 die 0986441561, VW: statt 07Z130073F die 07Z130073FX). Die Düsen sind laut Bosch die passenden, da wohl irgendwann die Nummer geändert wurde.

Das alle 5 Elemente defekt sind kommt mir auch immer noch sehr spanisch vor icon_rolleyes.gif
Die Vorgeschichte ist hier zu lesen: https://community.dieselschrauber.org/en/viewtopic.php?t=29744

Danach wurden alle 5 Elemente wieder ausgebaut und zum Bosch Dienst geschickt. Die haben dann für ordenlich Geld 3 Düsen geprüft. Nach Rücksprache mit mir haben wir dann beschlossen, die übrigen 2 nicht mehr zu prüfen, da es wohl sehr wahrscheinlich ist, dass diese den selben Defekt haben. Pro Element waren auch immerhin 80 Euro Prüfgebühr fällig...

Ich frage mich nur, wie der Motor vor der ganzen Geschichte bis auf das rödeln wegen der PDE Dichtungen einwandfrei lief. Ein mechanischer defekt wäre ja erklärbar, aber elektrisch defekt und alle auf einmal?

...aber gut die Düsen gingen durch diverse Hände und ich hatte mir die Nummern der Düsen nicht aufgeschrieben, bevor ich sie in fremde Hände gegeben habe icon_rolleyes.gif icon_confused.gif

Hello Andreas,

The "BIP signal" is nothing more than the current flow through a simple coil. By observing the current flow within an injection period, it is possible to determine when the solenoid valve in the PDE closes and the injection process begins.

These solenoid valves, like the nozzle mechanics in a PDE (pump-nozzle distributor), are subject to a certain degree of wear.

As long as the solenoid coil of the solenoid valve is electrically sound and the solenoid valve can open and close, a current (BIP) will be measurable. Please note that the respective circuits do not only consist of the solenoid coil of the magnetic valve, but also of its entire wiring up to the engine control unit.

Best regards, Rainer.
