Sorry haven't been on the site for a while as one year ago I gave the i-shift to my son. Looking back, I had a MTF oil change in 2017 73k miles by Dealer £61. The I-shift failed in 2018 80k miles and Clutch actuator was fixed. Another clutch actuator failure in Sept 20, 100k miles with the Clutch changed so the MTF oil changed again. Finally Feb 22 Gearbox actuator failed at 11700 miles and MTF oil chnaged again.
Each time the actuator was changed the mechanic did a dynamic and static learning. But as far as I know when the MTF oil was changed these learning aren't necessary.
Please look back at previous posts if you require info on the actuator failures.
