So.. Bit of background info, if I leave the car sat on the drive unused for 4-5 day it is unlikely to start, but fortuanlty the car is usually used most days so not really an issue.
Main problem is that if I'm out and tinkering with the car like tonight, been with ignition on for 10-15mins, external lights on and off a few time testing new bulbs. When I go to start it won't just the usual click and flicker of the needles.
Have KUFATEC E-MFA which shows 11.3v before attempted start and remains the same once failed start. Everything else still works fine at the point with ignition on ie stereo and lights. So didn't know if it was more of a amp thing?
Have been to halfords and they said when testing battery it say system noise, suggestion something running in background, but nothing on VCDS scan and didn't know if that was the canbus system still awake?
Car has a new can gateway from Eddie a couple years ago for a rns510.
Any help / suggestion would be greatly appreciated
