Hi all I have a 2000 W-Reg ML320. Recently I had a problem with it being stuck in limp mode and it seemed not to be getting out of 1st gear. Also the dash was not showing the P/N/R/D. I bought a second hand gear selector and have just put it in. The good news is that the car does now drive properly and goes smoothly through the gears as normal. The BAD news is that it is stuck in P and only using a pencil to release it manually can get it driving. My brake lights are working and earlier the old gear selector was coming out of P fine. Any ideas what could be the problem?
