Thanks found it now, couldn't see it for looking!
So my details are:-
Device part no. 5QA035858
Hardware: H24
Software: 0241
Am I right in thinking I've a mib2 and can update using the Spanish site as per posts earlier on in this thread?
Do I need to purchase a tool to clear the error codes and if so what does everyone recommend?
Yes you have MIB2, I would recommend buying OBDeleven Pro but there may be someone nearby who could clear the error for you. You will need to update the software in stages, not sure what the next one would be after 0241.
