Hi


Hopefully someone can point me to the right bank, I have a 3.0d V6 XF, and had the dreaded restricted performance message, I have a code reader, and it points to MAF Bank B, which one is this?


Didn't want to assume as you look at it, that the top is A and the bottom is B as you look at it.


Was going to swap the MAF's over, so next time if it comes up Bank A then I know it is the sensor rather then the loom, just to narrow the issue down to a specific sensor.


I did have them out and clean them carefully with the correct cleaner, and performance improved, but still went into limp mode, and the bottom MAF as you look at the engine bay is the dirtier of the two.


Also, would I be better off replacing the pair, or just the one?


All help and advice always appreciated
