UKPassats

hoping someone can point me in the right direction. i put my b6 07 1.9tdi passat through an MOT and it failed on a warning light on the dash EPB fault along with both rear discs. i dont have the software to retract the calipers so i removed the calipers and found the motors werent in the best of shapes so i replaced them both. as i dont have the software to retract to calipers the correct way i did it manually and rebuilt both calipers. rebuilt it all back up with a new EPB Switch. both calipers and motors work as they should. to reset the EPB within the calipers i pressed the EPB switch to move the motors out to thier out position causing the handbrake to be applied. it all works how it should however i still have the fault on the dash. how do i remove this. i have tried manual resets (lots of different button press's and brake pedal) but that doesnt work
