Yep the OBD port fuse blew on my Polo last week.
That means all the steering wheel controls stopped working and the headlights were on permanently. Why the OBD port drives those god knows & mr VW doesn't explain in it's fuse wiring diagram so of to the garage we went as I had no idea what to do.
My local garage talked to a VW parts supplier who said oh yeah sometimes they fail ( a feature no doubt), if not it needs a module & clock spring. They tested the circuits & fitted a new fuse, now I know what to check again.
The other option a new "module" & a "clock spring" was no doubt a less honest garage would have fitted.
