Hello,

Unfortunately, I'm having a problem where the engine (AFN TDI) of my beloved convertible won't start after I replaced the ESP (Electronic Stability Program).

We've already tried quite a few things, but nothing seems to work. The suspicion now is that the problem might be with the wiring harness (possibly a broken cable or something, as the individual cables are really in bad condition).

"Can anyone tell me if this wiring harness is available separately, or if there's a repair kit for it? Specifically, it's the wiring harness that runs from the 3-pin connector on the ESP."
Can it be replaced individually, or are there any bigger issues involved?

I would be grateful for any help, best regards.

"Does anyone perhaps have the part number for the engine wiring harness where the ESP connectors are attached? I would simply replace the entire harness."

Hi,
Starting to address the problem with the wiring harness without proper visibility is not necessarily the most effective approach.
You would have to replace the entire engine wiring harness, and those are probably no longer available new. I don't even want to talk about the amount of labor involved.

First, I would measure the input/output contacts on the ESP connectors.
Is RLF available for the injection system?
Selbstverständlich gehört auch ein Auslesen des MSG und der relevanten Meßwertblöcke dazu. VCDIs S available?

ja, sowas kommt vor. Habt Ihr die Einspritzleitungen entlüftet? Fördert die Pumpe Kraftstoff? SDoes ELAB handle that?
