Hey buddy, I recently did mine too.. Piece of piss job, you will however need to get yourself a set of torx screwdrivers. Other then that its a walk in the park mate..
Also if you are unsure of it being your ABS module, as I am sure you already know by now.. While driving around, or when ever it happens an it all lights up like a xmas tree.. Pull over an pop the bonnet (dont turn car off!), and disconnect the power harness to the module.. its black an has a red? slider clip on it, slide the clip far right an itll disconnect.. now put that some where it aint gunna get caught in the engine an go look at your dash.. You should see that only trac off trac low an abs lights are on, nothing else... if the engine light is still on even though the ABS module is disconnected then it is possible its your oil sender pump failing. But from what you just discribed it sounds EXACTLY like a faulty ABS module, it hapens too all of us man..
And replacing the module is easy, i think its 6 torx screws, and I think the size is 2.5? I can remember but easy fix man... $20 set from Super Cheap an your well on your way..
Hope this all helps bud
