I was looking to log into my engine ECU to try and adjust the EGR, but I keep getting communication errors. I have no such problem with any other of the many parameters I have tried so far, so don't really know where to start.
I have a genuine Ross-Tech KII interface, using the new VCDS (can't remember version, downloaded the updated 10.?? the other week), I am trying 12233 as the login code, although I am aware this may not be correct for my car.
I'm trying it on a 2000 plate A4, 2.5 TDi Quattro
I haven't posted on Ross-Tech yet, but have had a look through the site and can't see anything that might help (sorry Bear!)
