That code is for a catalytic converter running below maximum efficiency which can sometimes be caused by a faulty oxygen sensor or worst case the cat has had it. Your O2 sensor voltage activity live data (upstream and downstream) should show if it's the cat and whether it's bank one or bank two but test the sensors first. Regards, Kie

Go into climate settings on the touchscreen and make sure the recirc sensitivity setting is set to off, otherwise it can occasionally mist up a bit in this weather. Kie

The windscreen has two halves, electrically speaking and the fuses are in the engine compartment fusebox, numbers F14 and F15 (possibly model dependent). If it's not either fuse, then it might be the connector tucked away at the bottom corners of the screen which can be prone to corrosion. Regards, Kie

Make sure the rubber boots behind the headlamps are fitted properly. Kie

Put the nozzle in at an angle towards the rear, that should help. Kie

Hi Dave, have a look at the valve stems and if they're metal and have a nut fixing them to the rim, then you have the TPMS, if they're just ordinary rubber valves with no nut, then no. I don't think they have a dashboard failure indication for the main headlamps bulbs. Regards, Kie

No problem Dave, it's not the worst thing I've ever been called...! You might want to think about investing in a code reader yourself, they range from about a fiver for a bluetooth device up to, well, as much as you want to pay but even a cheap bluetooth one will give you most codes in your PCM if used with free or cheap software you can download to your smartphone. The good thing is you can go armed to the garage knowing most of which codes are present and with a bit of Googling and YouTube actually understand what they mean, a fiver has to be better than 135 quid a pop. 😊 Regards, Kie

I would clear all the codes and recheck after a run, sounds mostly soot related though. Check your battery/alternator voltage too. By the way, I have the factory workshop manual in PDF format, just let me know if you want a copy. Regards, Kie

Hard reset required perhaps? Disconnect your battery and hold the terminals together for a couple of minutes, you'll maybe have to reset your windows and sunroof if fitted when the battery is reconnected but nonetheless worth a try first. Regards, Kie

I'm Kie, been on other Jag forums for quite some time and I now own an XF, my previous Jag being an X-Type 3.0 AWD, great car but sadly gone now owing to someone else's ineptitude. Pleased to meet you all and I may know some members already but hope to contribute in some way. Thanks. Kie
