Hey guys. Quick question. I just installed a new universal BOSCH oxygen sensor, but I can't figure out how to wire it. The chart kinda makes sense, but I have five wires, and the new sensor only has 4? Can someone help me out?

OE wires: Black, white, gray, red, yellow

New wires: Black, gray, white, white

2001 Audi A4 quattro 1.8t

Thanksssss!

 

you have a wideband o2 sensor in your car and you need to replace it with either the Audi specific wideband or a universal wideband sensor.

 

Damn okay.. Thanks. I could only find info regarding WBO2 when searching around... So its a WB from the factory??

And damn.. now that I search these things seems a little tough to find. What are some good sites I can check besides Ecstuning.com?? Or think maybe I'd be better off getting this from a retail store? Anyone know what engine code would have WB O2? I'm guessing this has to do with the VIN split in 2001?

Sorry for all the questions, I'm really newb about this car still.... Just looking for a little direction

 

they started in either 2001 or 2001.5 having the widebands. just match your engine code for the correct one. you could try germanautoparts.com or purems.com for better pricing. you probably would need to have it ordered at any retail store other then from a dealership. its not an item most places would stock.
