CBZA

I ordered the ”bank 1, sensor 2” lambda sensor but am curious where it sits, can I reach it with my special 22 mm socket from the engine bay or do I have to remove a lot of plastic and go from under the car? CBZA 1.2TSI

Similar location to this so not possible from above: https://youtu.be/yXka-05Xmcw?si=mQAkxl6IBFpfrqkM

Had to change this on my 1.2 Yeti. Yes underneath but not too difficult to get to. I just drove one wheel up a driveway onto the edge of a high kerb. Could then crawl under and remove. They can be tight, so a good soak in penetrating oil helps and a hot exhaust can help too.

I used a lamda sensor socket to remove it, which is a deep socket with a slot along the side to put the cable through.

I replaced with the VW Part from TPS and fault code cleared. No problems for 4 years since

Thanks! I ordered that special deep slotted 22 mm socket so ready to go when it gets here. Been driving with this code for some time now and had no idea that it most certainly runs roo rich and explains the petrol smell outside of the car when idling. Also not good for the catalytic converter in the long run.
