I'm having a weird issue, I looked all through this thread and many others.

Basically I cannot shift it manually, about 50% of the time it will flash in between shifts for about 10-15 seconds then go into gear, or neutral. Now the funny thing is, the car works perfect in Auto mode, its only when I manually shift that is gives me issues.

I checked the hood switch and it was actually loose, the bracket and switch were not snug, so I re clipped everything in hoping that would fix it but it did not it is now nice and snug, I checked all others doors, all things are closed. Can I zip tie the switch pressed down just to rule out that its indeed closed all the way? I imagine if the switch was bad the car would stay in ZERO while starting like most others do. At first I was thinking that when switching manually the cars weight transfer was making the hood flex a bit and disengaging the switch, in auto mode weight transfer is less which would explain why it works in that mode, I might just be over thinking it though

Im hearing MAYBE a gear identification switch could be the issue? I have a part number for it, does anyone know how hard it is to change?

what was the result? Was it electrical

Gentlemen, Found this issue with my SMG and I fixed it, the problem were while i was driving the gear indicator light would flash at ALL times, when I came to a stop and release the brake pedal the transmission would shift to N and still blink, then I would have to place it back into gear, BUT.....If i kept the brake pedal on and hard the gear indicator would still flash but not jump out of gear, then while driving the COG light would illuminate and I would reset it with my Autoenginuity tool, the other problem that was having was that my PDC wouldn't work, so the fix was both Hood sensors (51237893575), the 2 that are on the front of the car that locks the hood in place. Once I changed those 2 out 2 days ago, no more issues and runs perfect!! PDC no issues!

Previous to this problem, my gears would skip and jump out gear and the problem was the Gear identification switch (23412229792). With all this said I changed the Salmon Relay just in case.

Hope this works for some of you out there!

My sisters pump om her M3 jsut gave out at 127,345. It was experiencing the gear shifting into neutral and staying there. Cog SMG light would come on along with the SES light. She replaced the salmon relay but that only bought days as it ultimetaly failed. She took it in the shop and awaiting from the Indie to see how much of her life it will cost her...lol....this sucks man. How can german engeneering be so flawed with these problems.

idiot dealer in solon today said when the SMG pump goes, they have to replace the whole SMG system plus the whole transmission. They want $5500 in parts alone and $1200 in labor...

Once the Hydro pump fails, are there any other corresponding parts that should be checked?

I would almost think your issue may be with the sensors in the shifter or the paddles. If your Gear Position Sensor goes bad the tranny will start shifting into 2nd to take off and my not use 6th gear. If it drives normal in auto mode I would think it's something with the manual shifting input sensors.

that is the most horrfic BS ever! Thats another example and proves what the dealers are trying to do! go to an inde shop man! For those in the California south region, go to AMB Service Center in Durate CA and ask for Rick. I owe that guy for helping me a lot with the SMG problems I have been dealing with. Tell him that Steven w/the Black M3 sent you!

My Ride: BMW E60 530i
What's up guys, I need some advice, I don't have an M3, I have a 2004 530i e60 with an SMG. 15 months ago my SMG pump failed at 48K, I spent 3K to fix it. Yesterday morning my SMG failed again, I was driving and it all of a sudden went into neutral, it didn't go back into gear, I towed the car to Bayside BMW (great neck , NY), same dealership that fixed my pump 15 months ago, my car currently has 72K, knowing that BMW cover all parts for 2 years... but my service adviser is telling me I might need a new transmission this time, this is without him even running a diagnose on my car. I'm excepting a call from him this afternoon, and I'm almost sure he will tell me I need a new transmission so they can avoid replacing the pump under warranty. Any advice on what I can when he calls? what questions can I ask... etc...

My Ride: 2002 m3 smg
Add me to the list

Hey guys! New to the forum. I have a 2002 m3 smg with 116xxx miles on it. With in the last 2 months I have had the smg light come on then go off after restarting the car. I had funny or miss shifts when the light came on. Now the car is stranded won't go into gear. If it does go into gear it pops out. I have replaced the relay and read countless posts and threads hooked up my scanner to receive a pump pressure code so I am almost 100% positive it's the pump. I called bmwna to make them aware of this thread and my problem. I hope others do the same. If anyone has suggestions on my next step please help. The pump alone is 2566 at the dealership in Ks. I am a pretty mechanically inclined guy. But the bleeding process and it being a BMW scares me.

So I've read every single post in this thread but I've not come across the things we were hoping to accomplish:
1) What is causing these SMG pump failures? Seems a lot of people have gone off and diagnosed the broken pumps but I haven't seen any conclusions.
2) Has anyone gotten anywhere with BMW to acknowledge this problem? Do we need to get a petition going in the hopes that BMW will issue a recall?

What I'm seeing is a lot of misdiagnosed problems that then require thousands to fix when most of the time it is an individual component, not the whole system. The issue is that there's not a singular part that causes them to fail, but the fail rate on indivudual parts when combined is high enough to cause a significant fail rate on the system as a whole.

To my knowledge BMW has not come up with any magical cure to solve this, partly because most of the misdiagnosed SMG issues are misdiagnosed in their shop.

The SMG transmission is a sum of a bunch of tiny parts. Obviously it is a normal getrag tranny, which has a clutch and flywheel that can have issues, also has the synchros which can fail, and then there's all the other magical parts that make a normal standard transmission fail. On top of that you have a hydraulic system which can leak, an electric pump that will at some point wear out, sensors that can go bad, actuators that can fail, and then there's all the little switches and gizmos like the brake pedal sensor, paddle shifters. Pile on top of that the stress we put on the system because of our individual driving styles - and please don't bullshit saying you baby your car, if that were the case you would have bought a prius.

My Ride: BMW M3 SMG
SMG pump failure April 24, 2012

I'm new to this blog/thread, but I'm very glad I checked it out. I recently took my '03 M3 SMG to Beverly Hills BMW service after the gearbox warning light came on and the car came out of gear into neutral while I was driving (pretty dangerous).

I was told that the SMG pump has issues and it could be "several thousand dollars" to fix it - they're "still investigating" - which to me means they're looking for ways to screw me out of as much as possible. I'm not sure when the last post was put on here, but I want to see what resolutions exist so I can weigh the options.

Ironically, the day after I took the car into BMW BH, I got an email from their Customer Care department offering a "Total Care" extended maintenance package for $5,200 - I'm wondering, per above, if this continues to be even more of an upsell as it seems my car never has problems until AFTER the car is out of warranty.

Any thoughts would be much appreciated as I'm going to make a decision this week on what to do.

I agree with MeanieMe - there is no real response and it seems BMW is purposely keeping this issue under wraps to keep charging SMG owners thousands at a time to maintain their cars. I'm definitely up for pushing the manufacturer on this issue as it is expensive, and very dangerous given how randomly/quickly it occurs.

Are you sure it's the pump and not something like the springs, gear position sensor or salmon relay? If you went to a dealer they probably told you its the pump before they even looked at the car.

This might help....

http://safercar.gov/Vehicle+Owners/

Near the bottom of this web page above there is a link where you guys can file a claim with NHTSA. It looks like a few of you already did, but im sure the more the better chances you have of action. It also looks like you can start a petition and get a defective investigation opened up where NHTSA investigates the complaint directly with BMW.. From what i read there was a Problem with E46 taillights and someone started a petition filed it with the above site and BMW released a TSB on it a few months later..

if someone already mentioned this sorry i read about 6 of the 9 pages.

Hi Guys,
I have a 2005 M3 Convertible. I just put 122k miles on it. My SMG pump has never failed as of yet. However i am posting this because my Mbox indicator light just lit up and wont turn off. I hope it is not the pump but from reading all these posts here it sounds like it might be happening after all. Does anyone have hookups on a SMG pump (new or used) and what should i expect to pay?
