Not sure on the MAF phil, will do some logging and check, will also unplug the MAF, just pre empting what may be needed.
Just gathering thoughts, on what it could be, read loads, and looks like its one of those too.
Turned the car on this morning, and got 3 beeps and a flashing temp light, but all ok, working fine, normal temp. Turned it off and on a few times throught the day and all ok now.
