bavareze

Hello,

My 1999 Audi A6 with 2.8V6 engine works just fine, no warning lights on.

I tried connecting to the car with a generic OBD2 tool. I got communication problem error.

Then i tried using VAG-COM K2 cable that i have. Still not working. I went to options -> test and i see i have:
K1 - short to ground
K2 - OK
CAN - not present.

i assume the K1 should be also OK. where should i start troubleshooting?

i checked fuse 12 (DLC) and it is ok.

thanks,
~B

i forgot to mention, my stereo is OEM.

Does the radio work? The stock radios in those cars will keep the K-Line at ground if they don't get any power at all.

radio works fine. but i will try removing it anyways later today.

after removing the stereo, both K1 and K2 have statuses OK.

however, neither VAG-COM or Innova OBD2 scanner would communicate with the care.

Ross Tech KII says "no communcation with controller"

i have no warning lights in dash, everything works like a dream and fuse 12 is ok. ideas, please?
