Went to a party, everything worked fine. Went out to start the car 3 hours later, my speedo/odo stopped working + the fuel gauge started to fluctuate. I checked the fuse and it's fine. The cluster seems fine. Did the output test in VCDS and all the needles worked as they should. I checked the vehicle speed in the engine module and it worked but when I checked in the Instrument module(17), the vehicle speed didn't move. What does that mean? I'm thinking it's the VSS. No fault code though. Really need help on this one

It's a Golf 2000 2.0L, APK, 5-speed manual
