A standard OBD2 code reader will work, by law it must have the standard connector if sold in the USA

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.

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!

Hi after driving my 2003 vw Passat I took


Sounds like you either need another lock cylinder for your ignition or your central electronics module needs to be readapted in the CPU. When you insert your key back in and turn to the start position does your car start? How about when you remove the key now? If it won't start now, or if the ignition lock cylinder doesn't move freely, then you probably need a lock cylinder. Adapting your central electronics involves finding someone with a VAG COM cable and laptop, with the information provided in the wiki at VAG COMs website. For instructions on replacing your ignition look in the forums on VWvortex.com

I need to know the location of the code scanner hookup in a 2003 VW Passat


All of the scanner ports on cars are required to be within a certain distance of the steering wheel. Typically they are not far under the steering wheel. Look for a cover if it is not clearly visible from under the dash.
OBD2 scanners will scan the engine components only...which is useful. If you want to read all your VW systems, you will need a VAG scan tool. You can find them for $50.
Good Luck!
