In your trunk area there should be a piece of carpet by your tail light just move that to the side and then you can access your bulb. Any problems please let me know.

SOURCE: need relay location
relay 1 engine compartment
fascia 2 relay 18 (if it is diesel) relay 10 (diesel again) and this could likely be the best candidate relay 4 fuel pump relay/glow plug relay
Now for the fuse box locations ... looking from the front of the car... the engine compartment fuse box is on the left side up near the firewall.
fascia two is the lowest of the two fuse panels on the drivers side under the dash to the right of the steering column (left if it was a right hand drive).
This took about 15 minutes to locate all the possible fuses, be that as it may if i missed it don't hesitate to ask me again.
Please take a moment to rate this solution thanks

SOURCE: VW P421 code
This is a common problem with V6 Passats. VW put out a TSB on this a few years ago.
The code is telling you that your catalytic converter (driver's side, I think) is bad. It's more than likely not bad.
VW put out a TSB on this a few years ago. TSB 05-13. The cause of the error code is basically an over sensitive ECU (computer of car/engine) and the fix is to have your ECU flashed with the latest and greatest software. Depending on your mileage they might do it under warranty - you'll have to check.
It's still possible that it might be a bad catalytic converter - and the dealership might try to tell you that either way. Call VW (1-800-822-8987) and ask them about the TSB (I couldn't find it online).
Tell the dealership you want the ECU flashed - it's much much cheaper than a cat. No sense replacing it if it's not bad
There is a federal warranty on catalytic converters - 8 yrs or 80k miles...
Hope this helps!

There is a tank under the hood with a STEERING WHEEL icon on it. DON"T OVERFILL and use only PENTOSIN
