Hey peep, finally bought my first XF-S last week and absolutely loving it and wondering why it took me this long to get one. It's a facelift 271hp in black on a 61 plate. So, I've just had the restricted performance warning, switched off for a few minutes and she ran fine, then it came up again. I'm getting these two codes: 9B0167 9B3364 I've searched on the web and can't find anything. Any help on what these are referencing would be extremely helpful. Many thanks, Alex
