All is now well! On return home from Sports Italia also discovered cooling fans not working and no air con and any code reader unable to communicate with Engine ECU, Was fearing worst re ECU, and could not find anybody who was prepared to have a look at it, so decided to start at the beginning, lets check all fuses, and lo and behold found fuse that controls Lambda's blown, replaced and suddenly fans work, air con works and code reader can communicate with ECU, so all reset, and just passed MOT with no written advisory's, so we can breath a huge sigh of relief!
Oh, and I actually managed to do 2764 miles last year! all of which were blasts over Exmoor/Dartmoor.
