2020 Q5 55 TSFIe running for 3 days on petrol only & 0% battery (on holiday and no rechargers available). On start up 4th day got Drive System error warning message but proceeded with 45 mile journey. Car was generally OK by noticed it sluggish uphills and Power meter wouldn't go above 25-30% even in Sport mode. Also cruise control inoperable. Also Power Recuperating/Recovery meter didn't register when braking or decelerating (meter stayed at 0%).
Noticed Charge level indicator was registering 50% halfway into trip and continued to rise until end of journey it was on 100%.
On restarting car 4 hours later, it showed 100% Power Meter with 28 mile range (normal). Hybrid mode worked fine all the way home, power back to normal and Cruise Control working.
Next day still all OK, no warning messages and 30% left in battery (Running mainly on Battery Save Mode).
I understood Power Recuperating was only good for small %'age of battery reclaim during braking & deceleration so how is it possible I've recuperated 100% in 45 mile trip. NB - I've travelling 300+ miles since last mains recharge 6 days ago!!
