Sequential M gearbox telltale light on

[Khantouch]

Hi All,
This warning light located under the tempreture gage appeared on Friday night,
I was on route to North London to a workmates leaving do and was sat in slow moving traffic for the majority of the journey there, however at this point there were no issues and I decided to carry on. When leaving and returning to the car and starting it the EML light also came on. I started to make my way back and 15 minutes into my journey I started to experience issues with the car defaulting to Neutral intermittently between gear changes and then would switch back into gear. As I went on it gradually became worse and I was having to select the shift pedals to put the car into gear. As it was late I couldn't be arsed with pulling up waiting for recovery and opted to drive the remaining 3 miles back however it got to a point where the car would not go back into gear and I had to pull up for a few minutes and start again. I made it back and had a pal plug it in the following day and the following displayed

Duty Cycle Hydraulic Unit
Additive Fuel Trim 2, Limit reached

Any information / help on the above will be appreciated as I will have to look elsewhere for the work to be completed as I am currently in dispute with my local dealer Berry BMW as I have had a bad experience after it was booked there for some work previously and would not trust them with car again.

Thank you in Advance
