Try running the adaptations with inpa, not ista. There's a 'M' menu for the smg where you can command each adaptation individually. DO NOT reduce pressure before or adaptations will fail. Make sure you keep battery voltage while running. Another car running and batteries jumped may not be enough, the M5 easily draws 40-50A with ignition on. Here are detailed instructions: https://www.m5board.com/threads/inpa-smg-adaptation.598572/#post-7511406

Did you just replace the motor and haven't been able to run since then? Bleeding once is not enough, follow jcolley procedure above.

No, I was not able to perform adaptation since I got the code even so with the new motor from MLRENG. I did tried with INPA to perform adaptation, no different. The most recent replacement was hydraulic pressure sensor before that was motor and before that was relay and before that was fuse. All of that didn’t really makes much difference. 4F43 first then eventually 4F42 for red cog transmission warning while engine running at idle.j

I will try jcolley’s procedure. When I tried to bleed, it failed. ISTA suggests that I bleed actuator first, but I never able to bleed actuator due to hydraulic not building pressure in time but jcolley’s procedure suggests to bleed slave first few times. I remember when I tried to bleed slave, it didn’t failed But it says something that I don’t remember.

I will try jcolley’s procedure and report back

I am performing bleed clutch just now as we speak. However the remaining time is counting at a negative number as opposed to positive on INPA

Take a look:

I remember getting negative time as well. However if this doesn't work I suspect you have some mechanical issue likely requiring trans to come out.

While I assumed venting for clutch was a success 5 times. I tried to bleed gearbox actuator.


And this is what I get:

Translate for the bleed gearbox actuator error: pressure build-up in the actuator block not reached in a given time

Yes that means clutch bleeding succeed. And that error suggests your top block has some issue. If I had to guess it could be the PWM pressure solenoid tip(s) broke. Trans out time I guess.

Flacoramos you might be right , but i would go for o-ring set first, mine was hard like wood. High temp plus high pressure and you got a leak

One more thing, in your earlier post, you mentioned about once your dealer replaced the sealing kit for the pump and it fixed the problem but prior to the fix, is it fair to think that the dealer was able to adapt the gearbox and bleed the actuator despite the actual issues? Was there “Tranmission! Perform adaptation” warning prompted on the dash?

They said they wasn't able to adapt gearbox, so they took car to bmw dealers where gearbox was adapted

Was it because hydraulic pressure too low? can You clarify who actually change the seals for the pump? Dealer or “they”?

Reason why they (independent car dealers) wasn't able adopt i don't know, i asked them about adaptation when I pick up car for second time they said BMW done it for them, cause they just cant do it themselves, whitch is a bit strange for garage specialists in M car( as they say)

4F42 SMG: Hyrdualic control unit: activation, pressure build up


4F43 SMG: Hyrdaulic unit: On period


4F44 SMG: Hydaulic unit, misuse (activation shift frequency)

Mine just the firsts two above.

I did a little test today, doing multiple shut down and turn on. What I noticed is that it takes precisely 1 minutes and 20 seconds to get yellow cog transmission warning, 4F43, that is. Temperature of hydraulic pressure doesn’t seems to affect. When I first got that error it just comes on then disappeared during the course of driving. Now it got worse. Precisely to one minutes. I think it got worse when I tried to top up the expansion tank or it was when I tried to perform transmission adapatation

When you got the yellow cog warning? Did your transmission defaults to D5 like in the attachment?

Ok I will try to disassemble the pump and snap a picture tonight.
