Re-adapted throttle body again as I didn't wait for it last time I undid the battery.
Cleaned up the contacts for the coolant level sensor. Dash warning's been going off these cold mornings when I've parked on a slope
Contacts looked OK but I gave them a brush up, level has been constant since summer so not sure what that's all about.... ?
Scanned for codes like I do once in a while - nowt
Re-set clock
