Hi guys,

I am trying to solve some electrical problems with my dear Polo 2002 1.4 16v 55kw BBY...

Can anyone share a ECU Wiring Diagram with me? with the ECU connector pin out, it has Marelli ecu

Thanks

Hi,
Were you able to find any helpful info about wiring?

I'm also looking for some schematics, specifically the pre cat o2 sensor connections would be of interest for me.

Thanks,

on VW Erwin you can get the PDFs for your car based on the VIN.
