Breakdown

Broke down on the way to MOT. This is the problem with SORN'd vehicles - there's no opportunity to test-drive them before you actually drive them to the MOT station.

Anyway, what happened here was entirely my fault - it later dawned on me that I'd underfilled the cooling system because I didn't even look at the expansion tank and made no attempt to turn the engine over to eliminate air locks after filling.

No damage, only to my pride.
