Of more immediate concern is that your oil warning light came on and you
only added a quarter litre of oil. I would have thought at least a litre
should have been added to bring the level up to the correct level. Ideally
above the knurled section on the dipstick at the top of the recessed area.

I think i found the correct oil (Castrol SLX Longlife-II) in Halfords
though looking at my notes again i've a sneaking suspicion now that it
may have been 506.00 which you're not meant to use for the PD engines
rather than 506.01. £13 for a litre and it was just above the min
mark so it took another 750ml or so.
