It’s finally happened; after two months of unerring service, the XF has finally displayed the first signs of electronic glitchery. The rear cabin light suddenly decided that it did not want to switch off. So after several attempts to turn it off, including a restart of the engine, I realised that I had no choice but to drive around with the interior lit-up. However, 10 minutes into the journey and the light magically switched itself off.

We faced similar issues when we ran the first-generation XF on a long-term test several years ago. The touch sensitive cabin lights were a terrible idea and they would come on without warning, and then refuse to turn off. Admittedly, the new XF has only had this glitch once and here’s hoping it stays that way.

Overall, though, it’s been a pleasant two months. The XF is practical, refined, comfortable and actually much nicer to drive than its understated looks might suggest. Would I buy this over a BMW 5 Series? As it stands, I probably would. As long as the lights stay off...
