Lambda sensor for S1

[nordberg]

Hi, leading on from my last post about mot failure due to emissions...I've finally got my car into a garage to change the oxygen sensor. However, after removing the old one he's noticed that the profile it's different on the new Bosch sensor. I'm going to be popping over to have a look later but my initial instincts were that Euro Car Parts had got it wrong, and sent me the wrong one. After analyzing and searching the internet for info, the Bosch LS615 seems to be the correct one for my car 🤔. Just wondered if any one else has had issues?
