I've got a W639 Vito (2007) and I've got a p0030 fault code come up which means I need to change the O2 oxygen sensor also known as a Lambda sensor. It's sensor 1 bank 1, so it's pre cat. I'm pretty handy with all this stuff and will replace it myself but I cannot find it!
I can see the cat but there's no sign of the sensor, could someone please give me the location? A photo of it would be great.
Thanks
