I'm sure someone will know what the codes mean. I recall p1339 was a anti-pollution alert but may be wrong!

MK1 16K miles have you any service history with the car? Just wondering if the timing chain has been changed? Because it will need doing and could be the issue but maybe it’s just down to the low mileage and may need a good blast

No history booklet only dvla mot history which doesn't guarantee miles.
Have had the chain checked with local garage who removed the rocker cover and plugged the crankshaft to lock and the chain is spot on
Thinking possible hpfp or maybe a duff injector only no 3 fault code
Thanks

Yeh possibly injector but at that mileage probably could do with some injector cleaner running through it I would try that before swapping parts, hp fuel pump usually throws up misfire on cylinder 4.

I have put in some fuel cleaner and done 80 miles but still missing,will try changing the injector from no 3 to no 4 to see if it fouls up no 4.if not I'm running low on head hair to keep pulling out!!!!

Just had a thought, a couple of years an owner posted a problem that no one could sort and they threw loads of parts and labour at it and the owner ended up sorting it himself and the problem was in the fuel tank where there is a low pressure pump and a filter and this filter was full of crap and needed cleaning out.
Something to look a when all else fails

P1339 is not listed in Peugeot code list's but is part the BMW Mini Prince engines fault codes associated with misfires on cylinders this may explain the misfire on No3 Cylinder 1-3
