I guess this is from London driving. Will get it cleaned and see how long that helps the issue for.

I had that one a couple of years ago. It's where the exhaust lambda sensor gets sooted up and gives a slow response... I kept clearing the fault code and it kept coming back. Booked the next service and mentioned the recurring fault but then before the service the problem went away and never came back! I discussed it with the technician who reckoned that a DPF regen will usually also burn the soot off this sensor and, in any case, the batch of software updates loaded during the service included a fix to make the system less sensitive to the slow response. It's never happened again...
