Wierd Lambda

So my car went for mot today

it passed the emmisions test somehow even though vagcom is telling me that the pre cat lambda sensor is dead i also have a sports cat!

i ordered a new bosch genuine sensor to replace it but didnt get delivered in time for mot so i decided just to give it a try and see

how the hell has it passed ?
 
They are a nice garage seeing as i used 2 work there ;)

I told them when i took it that it probs needed a lambda.

They dont pass things like that which need doing as i like 2 know my car is in top condition.

I will get a print out later and see how high low the readings all were.
