Hi Steve,
Thanks for your reply, I took it a local Audi dealer he knew where it would be straight away. It was behind the panel on the side of the dash, he said it's common for them to be moved if they have a tracker or something fitted apparently. I've got an ECM327 dongle that connects to an app on phone, it worked as well. It's thrown up a P22A7 code, something to do with the NOx sensor heater? I'm gonna get it looked at while it's under warranty I'm not messing with it.
