Update on this. It was a terminal in the plug. Terminal was not making a good connection with one of the pins on the o2 sensor plug. Extremely annoying but fixed

Thank you. I’ll give that a go too

Spoke too soon. EML came back on with the P0050 o2 sensor code 🤦‍♂️

Greatly appreciate your reply and advice. My brother has BMW software fortunately and has reset the adaptations. Re-ran for codes etc and all clear. Took it out and it’s back to its old self. Fingers crossed it all realigns and calms down following the reset. thanks again Adam

Hi all, New to the forum and also new to the 6 series! Hoping you might be able to help with my situation. ive had the car about a month and after a week it threw up a code, which turned out to be a stretched timing chain. The garage I bought from replaced this via their specialist FOC which was great. However since the replacement I had a P0050 o2 sensor bank 2 sensor 1 code. I replaced the o2 sensor (after much research into the correct BOSCH sensor - so many variations). All good for a day! Now the code is back. Adding to this, I now had the Po326 code thrown up ‘knock sensor 1 circuit range / performance bank 1 or single sensor’. Quite annoying. I wonder whether this all relates to the work on the timing chain? Or do I need to reset adaptations. any thoughts would be greatly appreciated cheers Adam
