p38 stuck in low gear

hi, i am new to the forum so please excuse if this has allready been asked! i have looked but cant see anywhere.
my p38 is stuck in low range i was sitting still chatting and accidently moved it across into low and it bleeped but straight away moved it back to high, and then drove off, on realising it had gone into low i stopped and attempted to put it back into high but it would not go in and will still not go in, it bleeps and the green lights flash on the right hand side of the gear selecter but it will not come out of low. can anybody help? please. thanks neil

I've had this problem whilst stuck in traffic and and pushed selector across to low by mistake. I had to pull over and select all gears one by leaving them to engage before moving on to the next gear. It then went back into high with no problems. Not sure if this is the right way but it worked for me.
Hope this helps

right i had this select neutral fault the other day tried everything , checked all ECU'S all fine motor sounds like its engaging but strangely lost clicking sounds from indicators and hazzards , but if i took key out of ignition the hazzards made the clicking noise whilst flashing , very odd , anyway i was stuck in low range , no sport or manual available and i had no high range gears and would crunch if tried to put into park , keeps saying select neutral and the selector lights will not settle they just flash and stuck in low range , well i went underneath the rangey and on the side of transfer box right next to motor there is a round switch with 2 prongs on it with 2 seperate cables connected to each prong , it was filthy oily, so i took off one crimped cable at a time - sprayed with WD40 cleaned up contacts on switch and crimp -- same again with other cable , and hey presto , all fixed straight into high range no problem , sport mode and manual mode worked also strangely i got the clicking noises back on the hazzards and indicators , i hope this helps someone who gets same fault , i am not sure if the switch i cleaned is the neutral switch mentioned in another post ,
