BMW 330ci E46 SMG/SSG Transmission Pump troubleshooting / replacement (Non M3)

- SMG Problems. My 2004 BMW e46 330ci has given me the cog of death on the instrument panel... The light looks like a gear with an exclamation point in the middle. Perhaps it should be a dollar sign in the cog instead. I asked a local mechanic the cost to look into this and it quickly became clear that the repair costs would exceed the book value of the car. This will be a boring video for 99.9% of you, but may just save the day for someone who had my problem. #smg #ssg #e46
This literally stopped the car from shifting out of first gear into neutral and I could not start it.
The car shifter says it's SMG - it has a sequential manual gearbox, but it is NOT an M3. It has also been called SSG to not be confused with the M3 equipment which is very different. It seems to be a rare car with a funky transmission. Here I will show you part of the troubleshooting procedure I worked through to get the car running again. I use a ratcheting 10mm wrench, Torx t30 bits, a new hydraulic SMG Pump, a flex head ratcheting 17mm wrench for the best fit on the tank cap, a fluid pump, and Pentosin CHF 11s hydraulic fluid.
Watch here as I decide it needs more fluid to work. • BMW 2004 e46 330ci SSG... Ultimately, this was not enough, so here we are continuing to diagnose the problem and replace the pump.
The car is jacked up, the heat shield is removed to expose the hydraulic pump and fluid tank. I test the pump, replace the pump, refill the fluid, and test drive. Ultimately, this seems to have solved the problem of the car not shifting.
I do a test drive and show the shifting and dash readouts. Is the car fixed? Time will tell, but I think this was the answer to a serious problem that left me stranded in traffic.
Disclaimer - I am not a professional mechanic, but I read a lot and have been wrenching longer than most viewers here have been alive. I am sharing this video to illustrate a problem I was presented with and the steps I followed to address it. Any work you do on your own car is done at your own risk. If you are a pro and can share your experiences, problems and solutions, they are welcome.
I had a really hard time finding much info on this topic, so I made the video to help. This is why I make the videos - a way to pass it forward.

Great job!
Brilliant video robdude. Thank you for saving us some doe
Happy to help. Let us all know how it works out for you!
I have the same EXACT year and color. Nice car!
In the warmer months, I plan to do the clutch and all that SSG parts associated.
Never had a issue. Just gonna freshen her up. She has 186K miles.
Good video!
Sounds great! Enjoy it. Fun car!
Same problem with my Z4. Great video. Waiting for the pump from Amazon. $200 and a few screws.
Let us know how it goes. Same setup?
@@robdude1969 yes, same setup. Interested in the bleeding process. Haven’t found anything on it on UA-cam. Probably won’t get to replace it until the weekend
@@robsmith2021 share what you find. So little info out here. We can help each other out.
Harikasın dostum, paylaşım için çok teşekkür ederim. Thank u so much
thank you, good luck! Please share your results.
@@robdude1969smg yağ pompası değişti, vites tepkileri ve hissi çok daha iyi. Umarım bu şekilde devam eder. Vites gecişleri her zaman daha sert ve agresif. Teşekkür ederim dostum
Great video! Did the new pump come with new seal or did you reuse the old seal? If you reused the old seal have you had any leaking issues since the video? Lastly, do you know where I could purchase a new seal if I wanted/needed a new seal. Thanks in advance!
it did come with a new seal. I bet if you took your old one to a good auto parts shop they could match it.
Your old pump probably has a lot of carbon buildup which explains the intermittent issue. Open up the pump motor and clean it out. Maybe put in a new carbon brushing.

ما هو الشي او الطرف الذي قمت بتغييره وشكراً.
لدي نفس المشكله 😅
Thanks for sharing, I had same problem with my smg. Where do you buy your pump?
From the links in description. I bought the cheaper one, but it’s not oem and I think it’s a bit louder than the original. The oem one is a bit more expensive. 🥺 good luck! The job is easier than the fear.
My 2004 BMW 330i SMG/SSG has the same symptoms. i just installed the same SMG Hydraulic Pump and Pentosin CHF11S fluid. After the installation, the gear is still in FcogN and not starting. I am getting the BMW code 4EF4 Shift-Travel Sensor. Do you know how to fix it? Thanks
Sorry, I have not yet had to deal with this one. GOOD LUCK!!!
Hey there. I love the video. I’ve been searching for about a year on how to fix this issue on my car. But I look at your list and see two pumps. One is 200 and one is 1200. Which I do I get? Mine has the same issue yours did.
that's the difference in OEM and off brands. I think the one I got is a little louder than the OEM part.
@@robdude1969 the only issue I’m having is the bolt connecting the line to the pump. How did you get it off ?
@@nathencarpenter4064 the one at around 17:30? I used open ended wrench. Good luck!!
I have a BMW 330 SMG. A few days ago it happened to me that
When you move the gear lever you can hear the pump and clutch operating but it sounds intermittent. The interior lighting focus raises and lowers the intensity.
It seems that the pump motor turns on and off. When trying to shift into first gear it suddenly comes in but then shifts back to N and then an error code comes on on the dashboard indicating F gear N
good luck!
There is a bleeding procedure u should do with INPA, the pump is pumping a bit to often for my feeling. The accumulators loose their nitrogen charge over time so u may get problems of overheating the pump or not enough pressure during high demands.
Sounds like great advice. The new pump is quite active.
What year is it?
