Hello,

I have a question about my lambda sensors.
I have the old type (only upstream sensor). I fitted a bosch universal LSH25c some time ago, i get no faults and everthing is fine.
But now i found that is not the correct part for my car as it should only be fitted and the later generation where there are downstream also...

Does any one know the difference between the old LJA1682AE and the new LNE1684BB upstream sensors.

I was planning to replace both as the original is now 16years old and could become slow.
