I originally posted this is the D3 section by mistake...
Had a minor heart attack this morning when my 2014 Disco came up with a warning "Gearbox is overheating". Admittedly I was in Sport mode, however I was crawling in traffic. The warning came up without any warning lights or sound, stayed on for about 3 seconds and then went away.
Got home, plugged in the Lynx and the only code present is P2787 which is "Clutch Temperature Too High - Over temperature". According to the workshop manual "Rear differential actuator active for prolonged duration due to driving style or terrain". The suggested fix is allow the diff to cool, reset the warning. It says the DTC is set when the clutch pack calculated temperature exceed 200 degrees C.
Driving style was "stuck in traffic". Terrain was "a flat road in a town". I had driven around 7 miles normally from the engine being cold.
Has anyone else experienced this? If my gearbox was genuinely overheating I would have at least expected some audible warning and a warning light, not a friendly reminder! If I had been looking at something out the window I probably could have missed it altogether. Plus if a DTC is set, then surely some warning symbol should be illuminated to warn me?
The vehicle is a 2014 SDV6 with about 46k miles.
Tom.
