2014 SD4 Dynamitic auto- just recently got the above codes, out of nowhere got stuck in park and stated gearbox fault. After waiting 40 mins it reset and was off again. Every few days since gets stuck in park but once driving drives fine. Just been told needs a new gearbox 4.5k!! Only don’t 80k mileages and as I say drives ok. Looking on line im not convinced the gearbox is dead if still driving. States in code hydraulic senor, could this be as simple as oil? Just seen post saying been told the same by main dealers and it’s then turned out to be an auxiliary battery or an electrical issues. Any view be gratefully received as don’t have 4.5k and tbh not sure I believe LR main dealer and tbh never dealt with such rude people. Thanks in advance.
