Well that’s the thing,I took it to the garage with a replacement that I’d bought ( the one in the picture) and the garage who I’ve used many times and are a very good set of chaps said after testing the bank 1 sensor 1 it’s working fine and the one I had bought was the wrong one ! They also mentioned that it had been de catted and straight pipes fitted by the previous owner, but when I looked in the folder of receipts it said sports cats had been fitted along with a different exhaust. I have to say that Lambda sensors,cats and straight pipes are something I know nothing about and have to trust the garage. Could it be that the engine light comes on because the exhaust system has been messed about with ? As far as I can see it has no detriment to the performance of the car. Below is the sensor I bought thinking it was the right one for the upstream of Bank 1 ![CCADE9A8-3A65-4D80-8A93-21CAA49C3717.png CCADE9A8-3A65-4D80-8A93-21CAA49C3717.png](https://zclub.net/community/data/attachments/57/57370-d0c61d0849986c0f389e52eef2492759.jpg)
