Fault code help

Thanks in my book it says 16806? Could it be the demise of the cat or something cheaper?
That was just a google search on 'VAGCOM 16804'...
I believe it's more likely to be the lambda sensor at fault rather than the cat.

Thanks I didn't think of trying google. Will the sensor have died? I've deleted the fault now so I'll see if it comes back. The mpg has dropped off could it be related?
That's pretty much what I had when my Lambda sensor was going off, the emissions system is sending the wrong signal back to the ECU and usually ends up dumping more fuel in. Mine also showed up as excessive hydrocarbons on the MOT.
I did have one thought though, you said you have had it since you got the gearbox replaced? Have they forgot to plug it back in, or perhaps damaged the wires? From memory bank 1 is the pre cat sensor, which means it's located somewhere between the engine block and the cat. I don't know exactly where as it'll vary between car models. But I reckon it's vulnerable to a heavy handed gearbox swap.

I've still not sorted this be will have to soon. I'm hoping it's the Lambda sensor and I guess it's the first sensor to have a look at. Where am I to find the sensor on the DP? I want to check it's propally fitted before I buy one at £120. I've held off doing this as I'd hoped to fit a turbo back system by now but unfortunately I don't no when that's going to happen lol.
Look at this on eBay:
