Hi Everyone,

This post is to share my experience in case it helps someone else.

I purchased a 2007 Passat Wagon as a first car for my son recently.

These three items were not working. I had a local VW mechanic troubleshoot the electrical for me.

He found that the three fuses that feed these things were not receiving power.

According to the line diagram he used, there was nothing between these fuse positions and the ECU.

Recommended fix was a new ECU plus labor at $960.

I only paid $2,800 for the car, so no go.

I started digging on the forums and discovered the solution.

Relay 460 behind the mini-glove box to the left of the steering wheel.

5 minutes to replace and $10 - $20 cost.

There are two relay 460 in this area, it's the one on the right. It's a load reduction relay that functions during cranking.

Never go to any shop that fails to be able to read or trace wiring by valid schematic or with proper tools to ascertain and can't give a valid cause of a resulted condition!

This is the schematic he gave me. He said it showed nothing between the ECU and the three dead fuse positions.

Several possibilities here:
1) That wiring diagram isn't the right one for your car.
2) The wiring diagram is wrong (not at all inconceivable).
3) We're missing something, but I'd want to see the complete set to try to figure out what.

But... If J519 (which really shouldn't be referred to as "the ECU") was at fault, SD39 and all the stuff downstream of it would have had no power either, right?

Yeah, it didn't make sense to me either, which is why I started searching the forums for posts with similar symptoms.
