There used to be a thread with the actual OE motor; it is essentially an ABS pump motor.

There are some accumulator specific codes. what diagnostic tool are you using? It may not have the exact same verbiage as bmw specific tools. If it's an obdII only tool, the error codes for smg can even be misleading.
You can't find even a handful of folks who have permanently fixed pressure problems with accumulators only. There are some, but it is few and far between, and I'd not even attempt this diagnosis without inpa/ncs expert tools, and no other diag tools.
I'd summarize the errors this way:
1. pressure alone is the pump; the accumulator won't keep the pump from getting to pressure, the weak dc motor will
2. a common error is on time too long; eg, taking too long to get to pressure, this too is a weak dc motor.
3. If you can find evidence that says the pump gets to pressure normally (5-6 seconds from observation, don't know what the diags would say) but is running too frequently, then you MAY have either a leak, low fluid, or an accumulator problem. But again, with the tools mentioned, there are a couple accumulator tests / specific error codes. I'm not sure anyone is on here anymore that can speak about this more clearly from expert experience.

I'm not sure what diagnostic tool my friend is using but he said it is expensive and I did the code reading through the phone with his instructions and the opening screen for the code reader said "BMW & Mini".
My friend has INPA but we wanted to see leads as to see what others have experienced with this code.

Not cheap, but the only other alternative is if you have a reputable electric motor rewinder/repairer.
Will this work with regular SMG or will this be for the SMG II? I can see some of the symptoms being similar to mines.

Did you buy the whole kit?(oil, grease, & temp sensor)) or just the motor itself?
What kind of software did you use for the code reading?

I bought the whole kit (motor,grease,oil, tenp sensor) the tool to release the pins was additional together with the accumulator.

I used inpa and ista for my car. I installed it last wednesday buy i have the cog light for smg adaptation and smg gearbox values. Hopefully nothing to worry about my mechanic told me that we just need to bleed the system again. When i installed the pump i forgot to put some oil in the return pipe

That fault code without a doubt means that the hydraulic unit is not able to build and hold pressure within the expected time frame. I've had that and it was getting worse every year until the pump completely died and had to recondition the motor locally. It lasted for 10k km then failed again and I replaced the whole hydraulic unit. Ouch ($$$)..

Works like a charm ever since (more than 2 years).

I too got the burkhart kit and cable tool. I bought mine from a US reseller, described here:
