Hey,

Was working on a 04.5 GLI 1.8t last night and having trouble logging .When the cluster fuse is in i cant log com is lost right away. With the fuse out i can log day and night but the car goes into limp from the missing VSS signal.

So typically i run a designated K-Line from the ecu to the OBD port but i get NO communication at all . I have done this countless times i ve checked all cables but no luck.

Any help would be awesome.

Car will should not go into limp because of missing VSS.

At least I don't have that issue.

This is what I said.

But running a dedicated K-line should allow you to connect as well.

plenty of people do 1.8t swaps into mk-whatevers with no vss and no limp.

I just drive with the cluster off and just bang off the rev limiter to know how fast I'm going while logging.

You don't have to do that.

You have to figure out why you are getting limp mode.
