February 24, 20241 yr Hi could anybody help with the problems I'm getting . When it happens the cars interior power will flash off and on including headlights the display will flash on and off some times stay off then back on and my steering will stiffen up alot like there's no powersteering. I've attached photos only other thing ive had pop up is check battery tterminals ha e checked all these and they are tight . All things clear and go back to normal when key is removed and restarted. Cheers
February 25, 20241 yr Morning Stephen Welcome to the Forum I was going to say battery (then read your post again) have you checked the Power Post under the bonnet is that tight? Otherwise it is a Diagnostic session Dave

Otherwise it is a Diagnostic session Dave Hi thanks for the reply. I've checked the rear end and all it tight I'll check the front today. My battery is a Yuasa HSB019 Silver 12V Car Battery its been registered can't be coded correctly due to being a 100ah can only be coded to a 90. Could this be the problem ?
February 26, 20241 yr My E53 has the same Battery, registering just regulates charging so I would check voltage at the under bonnet charging points Should be 12v+ (min) ignition on engine off 14v+ engine running. Quick thought is it registered as AGM which I believe yours will be? Is the IBS lead in the boot in good condition Good Hunting hope it's a simple fix Dave
July 6, 20241 yr Author Hi just thought I'd update my listing all my problems listed in this and in the pictures was due to an intermittent alternator regulator issue (over voltage) Cheers
