** EDIT REGARDING THE COST **
Just to clarify and try to answer all the questions surrounding the customer being charged to remove the gearbox a 2nd time.

HE WASN’T.

Perhaps I used the wrong phrase of words on the video without expanding (sorry for any confusion).

This video was recorded 2.5 years ago:

Work carried out 1st July 2020.
Video uploaded 4th July 2020.
Video published 5th Feb 2023.

I’ve just check the works invoice from 8th July 2020 and WE PAID FOR HALF THE LABOUR.

I can tell you the customer was very happy with that outcome.

I appreciate some people may still think that’s unacceptable and there’s not much I can do about that as everyone’s entitled to their own opinion.

Ourselves and the customer both came to the conclusion that neither party could have known about the Slave Cylinder ‘may’ cause the SMG not to adapt due to a 2017 BMW document (BMW released 12 years after production, and only 3 years before this work was carried out in 2020), and therefore we agreed to split the invoice as it was neither persons fault.

If it was anybody’s fault you could point the finger (and aim that negativity in your comments) towards the manufacturer BMW.

Thanks.
** END OF EDIT **


Here's an interesting twist to a common problem with BMW SMG transmissions.
This BMW E64 M6 uses the S85 V10 mated to the unique 7-speed 'SMG III' Gearbox.

SMG III was the last incarnation of the BMW SMG Gearbox before they moved to DCT Gearboxes in the F-series vehicles.
SMG I = E36 M3
SMG II = E46 M3
SMG III = E6x M5/M6

This V10 M6's Clutch Release Bearing failed (they split into 2 pieces), which led the Clutch to prematurely fail at just 42,000 miles.
Upon replacing all the items with new ones, the SMG Adaption process kept failing.
We tried it several times but each time it was unsuccessful.

One of the fault codes stored was:
4F67: SMG - Learning Not Run (Clutch Valve Values, Clutch Slipping Point).

The great thing about being connected to BMW's ISTA over-the-internet (directly to them) is the ability to check BMW PuMA which is an internal database of all known problems - however small.

During our checks, we found a PuMA case from 2017 where someone discovered that even without changing the Clutch you could get a strange fault code called 4F67.

4F67 is an internal fault with the Hydraulic Slave Cylinder (NOT the PLCD Sensor which lives inside the Slave Cylinder).
It seems to be an unknown mechanical fault (not electrical) that stops the Clutch Slave Cylinder from operating correctly, and therefore not passing the Adaptation Process.

We installed a new Clutch Slave Cylinder, and then the SMG Adaptation Process was successful first time.

We hope this video helps others who may be suffering from an SMG III Adaptation issue.
