I have an A6 4B 2.5TDI BJ2003 with 340.000km, where I can’t really read out something. except MSG, transmission, airbag, ABS and immobilizer I can’t read out anything. The ECUs don’t answer. You can hear some how he drives the ECUs, e.g. with the LWR you can hear the lights up and down for a short time and e.g. with the radio you can hear the drive or whatever. read out with VCDS 17.1.3, the reader can be excluded because it is on a passat B5 2003 per The real reason I want to read out is that my LWR sometimes appears in the AI and the parking assist only gives a long beep and that’s it. Can’t read it as I said. What could that be?? When testing the connection appears: K1 Line: Ready, K2 Line ready, Can: not ready
