On my 2003 4/4 I have fitted a
NTK KBA16693:OZA519-D1 8L5

Maybe the OZA519 is the critical part of the code

At http://www.lambdasensor.co.uk/main/ntkprice/price.pl?item=OZA519-D1

The NTK is £94.80 and their own brand at £60

I normally go for the NTK in the expectation of a better quality product


Good luck
