Hi!

While I was just looking at my pump cable, I noticed that pin 8 is missing and not present on the connector.
The pin configuration is 1-8 for the 2.5 TDI AAT engine.
Since the cable has a wire that's tapped into the overall wiring harness, I'm wondering what pin 8 is for.


Best regards: Marko

Hi.

Pin 8 of the 8-pin pump cable is not connected, at least in the case of the 1.9 models.

Hi!

Could it be a control interface for a GRA (Graphics Rendering Accelerator)?

No, even the schematics with GRA (presumably referring to a specific standard or technology) do not assign a function to pin 8 of the 8-pin connector.

Is pin 8 assigned? Where does the wire leading to the pump side go?

Hi Ulf!

The K.a. wire is definitely tapped below the connector and runs to the pump.

The cable, as far as I can tell, is cut below the plug and leads to the pump.


Hi Marko,

Unfortunately, I can't help you further; I only know about the 1.9 version.
