Hi All

​​​​i have a 2010 V6 XF Petrol.
Have a rather strange situation where I replaced the MAF air sensor months ago, all seemed of for a short time, then the orange check engine light would come on and off at different times.
I filled up with premium unleaded from BP one afternoon and noticed as I went through the tank that the light came on less and less.
Eventually I refilled on BP and now check engine light doesn't come on at all. When it did come on previously, diagnostic computer reported it was running a bit lean.

Is it possible that my engine only likes BP??? Or could this be indicative of a part of sensor having issues?

Thanks, I understand BP is a higher quality fuel but seems odd that I get an engine light if I choose Caltex or something different one day
Cheers

 

Without checking the codes it's all a guess?

Sure, attaching a screenshot from my cheap wireless fault reader, don't have the proper equipment. Lots of different things came up, I'm assuming this is what mechanic saw months ago
Thank you kindly for any insights offered.
