I suspect the cable length or the connector might be different. If you can post the length and a picture of the connector, I can compare it to my 028 130 201 H.
The H or HX (exchange unit, €194) was used in the Audi 80/90 and Cabrio models. The engine code for this is 1Z. Therefore, it should fit. It was installed from chassis number 8C-P-059 001 onwards. Before that, the part number was 028 130 201 AX (€185) up to chassis number 8C-P-059 000.
