Hi, driving along tonight and the dash lights up like a Christmas tree with numberous faults. Gearbox fault, HDC fault, stability control fault flashing constantly. Got home and switched off the engine and started again and faults disappeared. I've no doubt they will reappear tomorrow. Any suggestions you good people. I drive a 2014 Discovery 4. TIA

See the suggestions as to the possible cause. Low system voltage is the likely issue. You just need to find the culprit, but the alternator is a good place to start.
D3/D4 very battery and alternator dependent
As above check voltage, my alternator failed recently and my D3 got a mind of its own. I replaced the alternator myself and paid £85 to have the original denso fixed as a spare. Thankfully the battery remained healthy as i did not use the vehicle at all
Find that DC voltage reader quick!
