HI have freelander 2 have a tail light problem one only working but all fuses ok but was checking them but forgot to release key fob and only relised half way through checking fuses now it will not turn over and has message HDC not availbe temp gauge goes to max all lights on and hazards going

hmm I'll be honest I'm not sure about this really but are there any fault codes have you tried a hard reset is the battery ok luckily I've not experienced many electrical faults on my FL2 but the later ones like mine had wiring from the evoque in a lot of areas which lights in particular are not working Jules

I'd say the battery is dead. Hyundai Ioniq 5 Ultimate. The family car.
2009 Rimini Red SE TD4. Gone.
2006 Tonga Green i6 HSE. Gone.
Audi A5 convertible, my daily driver.
1972 Hillman Avenger GT, the project.

Charge the battery.

You may find it necessary to get a new one if its more than a few years old.
