Help!! E46 M3 Stuck in gear, won't start.

Hey Guys,

I'm having a bit of an issue with my 2006 E46 M3. Drove it this morning and all was well, parked it for two hours in the garage. When I returned and tried to start the car I had no luck, upon further investigation I realized that although the stick is in the "neutral" position the cars gearbox is stuck in gear. The dash doesn't display a gear; however when I turn the key the reverse lights come on.

The "Cog" SMG light has been on for a few months but I have had no prior issues with the gearbox at all.

I checked the hood sensor, and unplugged and plugged in the battery (Thinking the car would get it bearings and realize what bloody gear it was in!) with no luck.

Is the gearbox just done? I'm a bit worried.

Has anyone else run into this issue and found a way to get the car to start?

Any help is appreciated, Cheers.

Try to change the salmon with a new one.
Otherwise, it could be your SMG pump.

Do you hear the pump going (buzzing) after opening your door? Did you apply pressure when stepping on the BRAKE?

1. Change the fluid
then
2. Check the smg hyd pump/relays/electrical
then
3. Need to buy a new pump

Agreed.

Again, agreed. More photos on a separate thread is appropriate.

Update, Replaced the Battery and the Salmon colored SMG relay. Now the stick will move to different positions, however it wont change gear.

So although I move the shifter from the "R" position to the "N" position the actual gear displayed does not change, although the small diagram next to it lights up the correct gear.

Could this still be a fluid problem? I can hear the pump when I initially turn the key but not after, nor if I take the key out and try again.

Also, question 2... After replacing the relay, does the car take a day or a few hours to run again? Does it have to get used to the new relay? For anyone who has replaced the SMG relay did you do so with the battery disconnected?

Did you notice any immediate changes or did it take a little while for everything to be back to normal..

When you switch gear, can you hear pump sound?
It should sound like a classy blow off valve and you can only hear it when the engine is off.
If you can, then it's definitely not the pump. SMG light on for a few months is never good.
