As I understand it the 1st one is the input for the closed loop fuelling and the 2nd one keeps a check on your cat.

Thanks-- i see-so the fuelling is worked out from the first one,which i presume if there were any running probs caused by the lambda,it would be the first one to look at first.

I understand that to be correct. And the good news is you can only get one from a dealer and it's ridiculously priced - around £240 + VAT IIRC.
