Merry Christmas & Compliments of the Season.
I would get the car scanned when you get a chance,
Because there will be a under lying malfunction that you have reset with a ECU reset, which now will be in the history log.
The fault may of occurred due to refrigerant gas is low, and HVAC was locked out because of the same, due to it had activated the Low Pressure Switch,
I am waiting for mine to do the same.
As I was under my car changing the oil & filter not long ago, and while I had the cover off under the car [as you do to replace the oil filter] and waiting for the oil to drain out, I removed the front plastic shield to check everything at the front end was in tact, and noticed a green florescent oil on the underneath side of low pressure pipe, between the [rubber] hose compression fittings, so this is an indication there is a very slow leak at one of the fittings,
mine is 2012 Series 2,
so yours being a Series 1 and is 3 years older than mine,
I would put my money on you may have the same problem, most likely heat, vibration and pressure the hose has deuterated over the years.
I have looked for a replacement pipes, and they are not cheap, approx. $380 +GST, as they are a dual hose/pipe configuration.
I am going to ring around in the new year and ask the hydraulic hose repairers the cost of re-fitting off both ends,
surely it has to be cheaper than $380.
Taking into account the system has to be vacc'd out anyway to replace/repair the pipes, and re-gassed at approx. $170.
