Di2 rear mech not adjusting.

I have a specialized Tarmac disc with Di2. It was all working perfect until last week, then it started getting a little noisy in the upper/easy gears. I went to adjust it this morning. In the smaller chainring at the front, it won't shift into the upper cog (28t). it wont stay in the third cog from the top either. It shifts onto the 11, at the bottom of the cassette, which it's not supposed to do. Ive adjusted the upper and lower limit screws and tried the instructions online to adjust it. the only way I am able to adjust it, is to go down, so i can stop it before the second last cog at the back, and then when it is at the smallest cog, it gives 2 shifts at the bottom, before it starts moving up the cassette, and then it stops on the 9th cog instead of all the way up to the 11th.
The chain is almost new, the bike has only about 2000km on it.
I've also tried the crash reset on it, I am wondering if there is a full reset anywhere? I had di2 on my other bike and never had an issue with it, any help is appreciated, thanks.
