Used my friends e39...when I was about to return it I went to put some gas, put the tranny in "P" (tiptronic) and shut off the engine while filling. After filling her up the car won't start. The problem was the check control display was telling me I was at "D" drive position, but the gear lever was at "P". this is what I did, I played with the lever put it in P-R-N-D and tiptronic mode a couple of times and then back to N or P but still the CC display says im at D. disconnected the battery for 30 mins. still the same.Took out and cleaned the selector lever switch (had a hard time takin it out!mind you) still the same. CC says im at D so the car wouldn't start does not matter where you put the lever CC indicates "D" all the time...any ideas? I left the car at the gas station...by the way its a 1999 e39 523i tiptronic

to get it going try jumping the starter with the key in the run position, jump battery power to the 10mm nut on the starter, you can usually do it with a screwdriver off the 13mm nut where the power goes to the starter

If you've cleaned the selector switch, the only thing I can think of is a short in the wiring somewhere...

Selector/gearbox ground failed?

Are these cars fitted with an inhibit switch?

have no idea...im not familiar with the e39. if that was my e34 i'd know that'll only be the selector switch...dammit I'm getting paranoid, I hope its not the comp.box:(

shouldn't hurt anything, if you short the 13mm terminal to ground your screwdriver may get a little shorter but other then that it should be fine, if it's nothing but the system thinking it's not in park or neutral it should start and run, may or may not shift right depending on what is wrong, the tranny computer may get pissy and go into limp mode if the computer doesn't get the proper signal for gear position, if it thinks it's in drive it may drive fine

It was raining really hard and its difficult to do it so I just had it towed to the shop...they can't even find whats wrong with it...they said to leave it a couple of days so they can check.anyone had this problem before?

Did you try to start it in Neutral? Did the Dash recognize the gear as you pick a different one? Probably a tranny switch.

I tried moving the lever in P-R-N-D and tipronic mode but the cluster stayed in D. Cleaned the selector lever switch ...still the same.

Time to let the dealer fix it for you.

Problem fixed!!! We traced the wires which leads to the lever switch that goes to the instrument cluster then to the box...To our surprise when we took out the glove box hidden in the upper portion was two additional 7.5amp fuses! which where blown! Changed it then prob.solved! cheez...after all the troubles it was only those two fraken fuses!!! damn, I wonder why BMW would hide those fuses
