I've got a 2002 Jetta. I used a Double Pole Double Throw switch to go between bypass and full K-line. The colours/pins should be the same as your car:

I just cut the K-line going to the cluster plug and the K-line to the OBD port. I connected each end of the cut wires to the switch as illustrated. Mounted the switch behind the fuse cover door in the plastic above the fuse panel. Flip it one way for logging (bypass) and the other for diagnostics (normal). Works great. Never fails to connect or log in bypass. Give it a go...

Caveat. I did that diagram a couple of beers into the night. All pins are from memory. K-line is Grey/White so if that doesn't match, go no further.

This is what I did too. Zero probs logging with it switched

Yeah sorry I didn't have that picture when you did it SB. I rescued it from my hard drive when I was home at Christmas. I've been meaning the throw it up again but forgetting. This thread presented the opportunity.

Finished my switch. I'll deal with double slow innit if i need to.

I used a NC NO C button that switches between normal, through cluster comm (for vcds modules that need cluster info) and direct to ecu for me7L. One terminal (NO) soldered to a bridge wire to the W-line into cluster (double way comm to-from ecu/cluster) and the other terminal (NC) soldered to the K-line that leaves the cluster. Then constant (C) goes to the OBD2 port. No problems logging at any speeds.

Another thing i'm having issue with is getting my genuine ross-tech cable to work with both vcds and me7l. I have to re-try my VCP driver install, even in dumb mode it's giving me an error exit code 1, echo test failed. Even though it communicates fine through USB for vcds...

another nicety is the led is the same indiglo blue hue of the dash.

Wow. Nice job sir. Way more classy than my hack job.

Sorry can't help with the VCDS. I've never tried to use my Hex-Can with anything else. I just buy blue KKL cables and use those so I won't have to beg Uwe to fix a fubar'd VCDS cable should the worst happen.

Yup. I paid $475 in Canadian Pesos for mine. I try not to even lend it out, but I have a buddy at work that uses it more than I do. He works on cars on the side. When he walks up to my desk I reflexively ask "You need the VCDS cable?" Sometimes he says no Roll Eyes
