Thank you for all your replies. I also tried some redex and turbo cleaner that you place in the fuel. Just starting with the easiest fixes first.
That seemed to have reduce the occurrences. It disappeared for a few weeks and came back again today. I’m going to add some more and also clean the boost control valve.

Will update and continue monitoring before performing more expensive repairs
Thanks again for everyone’s input. Very much appreciated and confident will find the solution. At the minute, a code reader reset seems to be keeping the gremlin at bay
