Mitsubishi ASX 2011: Low coolant engine warning light

The day after the 120,000km service was done on my 2011 Mitsubishi ASX turbo-diesel, which included having the coolant replaced, the low coolant engine warning light came on. I found the coolant reservoir was empty and had the car towed back to the dealership where the mechanic informed me that it must have been an air lock. He said he ran the engine for 30 min after refilling it with new coolant and this should have been enough time to expel the air. He used approx. a litre of coolant to refill the reservoir. Could an air lock cause this, or wasn't the coolant reservoir properly refilled? Could the engine have sustained any damage with the low level of coolant?

An air lock could have caused the problem. I doubt very much if your engine would have suffered any damage as the result of the short time it was low on coolant.
