HI all,
I've had the dreaded wet foot well scenario in my Passatt. Its left me with an 01222 error - 30-00 open or short to plus fault showing in VACOM.

I've dried the floor carpet out, and left the sensor in the airing cupboard for several days, but after clearing the fault it, comes straight back.

I swapped NS and OS sensors and the fault moved to show drivers sensor fault 01221, passengers side now OK. so i am pretty sure the sensor is U/S.

My question is I have read in a few posts where a second hand unit was used and the fault changed to "wrong or not programmed"' or something similar - so are these, despite being the same part number, somehow coded to a certain model or can that be overcome with VAGCOM?

Thanks

Paul
