Hi all, just an update to my previous post. Finally resolved my problem, with no help from BMW…… Had to replace the generator/starter/alternator unit to sort the problem, having 1st replaced the 48v battery to eliminate that from being the problem, which it wasn’t. So just over 3 years old, less than 70k on the clock and the MHEV system started breaking down. As time went on the issue got worse and resulted in numerous unexpected ‘shut downs’ whilst driving and on one occasion a complete electrical failure due to a flat 12v battery which wasn’t being charged. Lesson from that episode was that I constantly charged the battery when not in use to avoid a si,liar situation…. Hearing more and more people with the same problem and BMW parts confirming they are getting numerous enquiries every week for the component, so clearly BMW have a longevity issue with the system. Going to be a lot of unhappy customers. BMW of course denied there was an issue , weren’t willing to resolve the problem and instead said ‘take it to a main dealer have them identify the problem and if clearly a BMW design or manufacturing problem, they might consider a contribution to the cost’. I could see running up a huge bill at main dealer rates and then getting a minor contribution from BMW if I was lucky so opted to get it fixed by my local independent who was excellent with it. Fortunately, the vehicle was fixed and drove like a dream again, I forgot how good it was! But as the title says MHEV owners beware!1
