The second one is literally right in the middle of the car. In the exhaust pipe, obviously

Hi Jobsworth.

Thank you for your reply, I just ordered the sensor... do I need to replace them in pairs?

Hi Jobsworth.

Mercedes don’t, but I probably would unless you know the front one has already been replaced

Cool, thank you mate. Is the front one the same as the back one ? I do believe so..
