I'm about to delve into VCDS measuring blocks to see if I can suss out which sensors are giving out dodgy readings - anybody know what I should be looking for? I did a trial run earlier and had a look through all the different readings and blocks, so I've an idea where to look now, I just don't know HOW to look and WHAT to look for

I checked with the place that did my cats, they haven't sold or fitted 100cel cats for about 6 years due to MOT failures and too many customer complaints. No Faults Found or DTCs not supported by controller or a communication error occurred Here's my VCDS log:-Īddress 01: Engine Labels: 4D0-907-560-AVP.lblġ6814 - Catalyst System Bank 2: Efficiency Below Thresholdġ6804 - Catalyst System Bank 1: Efficiency Below Thresholdġ8047 - Accelerator Position Sensor 1/2 (G79/G185): Implausible SignalĪddress 03: ABS Brakes Labels: 8D0-907-389.lbl Well I'm sat here totally at a loss as to how to trace which of these o2 sensors are goosed.
