I don't know what parameters the tool use to read the pressure inside the accumulator but i do know that you can also use the live data test (in my previous posts) to get an idea of the charge. (I believe this is how the foxwell tool also figures out the pressure inside the accumulator). The accumulator works in conjunction with the hydraulic pressure sensor. Whenever you opened your lines again, you will have to wait another 1000 KM. The other tools to use that won't have to wait until 1000 KM is the DIS and INPA.
Fair enough. I'll wait 1000km before attempting again. All I know is that the motor primes for 3-4 seconds now when I open my door. It would be a shame for it to prematurely die because of a bad accumulator.

I don't have LIVE DATA selection in Drive - SMG transmission

Tried this again with charger connected...didn't ask about battery voltage at the beginning of the test. Heard the pump going crazy and the motor continually priming. Finally got a completed correctly message

It doesn't hang up. It will say test "end" that is when you can press ok.
pressing ok will take you to the next screen where it says ended correctly.

If it doesnt say test "ended" pressing Ok will not result in a message saying test ended correctly. It will just most likely take you to another menu or screen without any message.

it's on there. I will have to check the exact menu order again. I use this feature very often because I keep a close eye on the hydraulic fluid temperature, during hot days driving and also after I parked the car after a long drive.

Thank you sir for clarifying! That then completes my SMG motor swap.

Hey everyone!

I just found this thread today and have been in the process of relocating the SMG pump on my 02 M3. I had to fab up my own bracket because no one makes one for the 01-02 models yet.

One idea I had was to relocate the accumulator so that it could be detached from the SMG pump and mounted separately. This would also allow us to purchase a much cheaper accumulator that is potentially refillable. Can anyone with accumulator knowledge chime in on whether or not this is a good idea? I don't know if the additional length of hydraulic hose will affect functionality of the acc.

So the car has been awesome. Shifts feel good...the other day it was 25'c and I was running errands in town and not a blip. Motor primes take roughly 4-5 seconds.

The only thing I'm concerned with is the ACC. When I open the door (after being away for over an hour) and I hear the motor prime, if I get in & turn key over, leave engine off, I can shift 3-4 times before I hear the motor prime again. Does this mean 3-4 shifts before the ACC needs to be filled again by the motor?

If yes, I'm curious, if anyone with a newly installed ACC, can try the scenario above and tell me how many shifts you get before you hear your motor prime.

3-4 shifts is about right.

That sounds about right.
Also it's normal for the motor to engage and prime the system any time you turn the car off and then unlock the doors after having stepped away. The system will always assume you are about to drive off and will prime itself in preparation.
