Hello Everyone,

I have two problems with my car:

1. The interior light no longer comes on when I open the door, I checked the buld and it is fine. WDF??

2. Trouble code P0134, Bank 1 Sensor 1. I checked the resistance in the sensor and it is fine. What else could be wrong with it?

Thanks for the help!

 

I got same error code on my 00 Passat V6. Dealer said it was drivers side(bank 1)cat. Took to where I bought it, they put on OEM equiv. cat. The light came back on within 2 weeks.... can't figure it out, kind of gave up.... any luck with yours??
