Default OBD read failure, to top it all off... $%^&!

I brought my car in for inspection. Everything passed, except that they couldn't get a computer reading. So they failed me. The dealer says they can't see me for several weeks. I read up on the forum and saw the note about the possible blown fuse. I figured that maybe it might've blown in conjunction with the instrument cluster swap, plus I'm now getting the signal relay click-athon going. I pulled the fuse--looks perfectly good.

So, has anyone had an OBD failure for some other cause?

This is just great, on top of everything else... I've never been stranded by my TT, but the continual barrage of annoyances is taking its toll. Just last week my driver side window no longer goes up/down automatically (doesn't auto-adjust for door open/close either). I could go on, but I don't want to take up the space.

do you have an after-market H/U?

Hi Jeff - no, straight stock setup for engine/electrical.

there is an "interior" fuse that protects the port, check for it.

You mean aside from the fuse in the electrical fuse board on the driver's side of the dashboard?

Default Yes, I checked the 7.5A fuse and it looked fine. I'm going to get a fuse tester and...

See if there is current with the fuse installed.

But if it's showing OK, I wonder what else could be wrong? Maybe the DMV technician goofed and didn't have the interface plug seated properly. I'll have to try it out again.
