hi i have a polo 2.1 2013 match edition i have had a problem with the injector no 2 intermittently failing, with the code P0202 00 [167] - Circuit Malfunction, its now happening consistently, and i cant use my car i have tested the wiring to the ECU from the injector no 2 plug and its fine, i have replaced the injector recommended by the VW agent, no difference i have tested the signal to the injector with a node lamp and there is no signal, i have tested the cylinders 1 and 3 and there fine, the lamp is flickering with the signal from the ECU, i can only presume that its the ECU, i have sent it away for testing but there saying that they cannot test, or repair or even program or a second hand unit. do anyone have any solution how to overcome this as my car is stuck on the drive and i cant use it.
the ECU is a 03P 906 021 AK https://www.uk-polos.net/download/file. ... ew&id=9722
