Need Help!! scanner "linking error" what do I do???
 

I have a 2001 A4 Quattro. The car was running just fine yesterday and all of a sudden the CEL came on...... I previously purchased a vag can scanner to aid me in removing any unnecessary CELS. The problem is..... when I try connecting to the obd2 port thr scanner lights up and stays on but when trying to do a scan after a few seconds the words "linking Error"keep coming up. removed the battery terminal to reset the CEL and it worked but for some odd reason the scanner still comes with the "LInking Error"!!!! Anyone know what it may be?? please let me know

You probably have not configured the software to connect to the proper serial port on your laptop.
You need to go to your Device Manager in Windows and see which port is used (COM1, COM2, COM3, etc... after you installed the USB to Serial driver), then match this in the VAG-COM software and test the connection.

when i got link error my car wasnt recognizing my ECU and neither was vag or the OBD II. i had to get a new ecu... mine got wet. everything looked fine. but link error came up as soon as the car stopped starting. your car running ok?!

i have the same issue with my car. it will run fine then all the sudden won't hit 10psi any more. Then after a while it throws a CEL but i can't scan it do to the linking error. WTF!!!!!!!!!
