hello crackstar I need your help. I have a 07 is220d and its driving me crazy sometimes fob won’t unlock doors when this happens the horn, side lights, roof light, windscreen washer door locks from main panel and windows doesn’t work (only driver side windows works from main switch). It’s really a pain but I also realised after 3 hours driving in the motorway everything went back to normal and was working as usual. So it’s an intermiten issue. On the next day same situation again - please could you help me with this? 
regards

The windows not working from the drivers panel is a sign that the window system needs ‘re-learning’ this happens after a loss of power to the system ( ie Battery removal) and it is a simple fix.

check Battery terminals are nice and snug and any Earth points you can see. Also I see you Battery was fitted Sep 2018 so might be worth having that checked as it’s now over 2 1/2years old and DERV’s do give batteries a pounding especially if it’s not a top brand.
