Hi, I'll try and give you the brief version of the story as it's quite long! The clip came off the gear rod on my 2001 E55 and I was in drive at the time, but not knowing this I was trying to park so I moved the lever and only had forward. I found the problem and fitted a new clip, the car was fine but when I went to it a few days later it was showing R when in park. Eventually after running through the gears it started but still showing R, then after a while all went back to normal. This kept happening every day so I put another shifter on and same thing, but then that shifter went really bad and put it in limp with severe banging into gear. It wouldn't clear the code so I swapped the shifters over again and codes cleared car was fine. Next day same problem but I had to clear the codes and then it was fine, it's as if something got damaged when the rod came off which is now killing gear shifters. When the car's warmed up it's perfect but the next day my display for the gears is wrong and no start without repeatedly moving the shifter, then it starts and if I turn it off then ignition back on I have to wait for R to turn to P and all OK....When warmed up I don't have to wait. Here's what I got last time it was in limp mode, only one current fault P2602, after lots of searching found about 30 people who'd had that code and a new battery cured it but it didn't cure mine. Everything points to the shifter being faulty but I'm reluctant to fit a third because of it already killing two. Any ideas what could have been damaged when the box was telling the TCU it was in drive but the shifter was telling it other things, and therefore killing shifter PCB's? First that comes to mind is the TCU itself, but with the fact it corrects itself when warm could mean the conductor plate? Today I'm back in limp mode after running it with the shifter plug off to check connections and now I have no gear display. By the time I drive it a mile to my mates computer it shows no codes because it's working, although now it should be the same as the pics. Any advise would be welcome as this is driving me round the twist! Cheers.
