Hi, I'm looking for a engine/injector wiring loom that goes from the ECU (8P0 907 115 T Med 9.1) to the injectors (06F906036A) for a Audi A3 2008 2.0L TFSI Quattro due to an intermittent misfire issue on cylinder no. 4. Cost from TPS for genuine replacement is astronomical, any help would be appreciated (e.g. where to source a replacement, correct part no., etc)
