Electrical problems with the BMW X5 Diesel 2011: Flickering lights and weak battery

Hi everyone, I need your help. I drive a 2011 BMW X5 Diesel with about 130,000 km on the clock. Recently it has started having electrical problems - the lights are flickering, the battery is weak especially when starting and general electrical problems. The fault memory keeps showing up and I suspect problems with terminal 30. Has anyone ever had similar problems and can tell me about their experience at the mechanic? My last visit to the garage wasn't that great. Many thanks in advance!

automatic heating control no longer works. Manual fan control works

If your automatic heating control isn't working but manual fan control is, it could be an issue with the climate control module or the temperature sensor. Start by checking the fuse for the automatic climate control system. If the fuse is fine, it might be worth having a professional mechanic inspect the climate control module and temperature sensor. Please keep us updated on your progress.

Why is this switched off, can you change this Raley, disconnect the battery or?

Yes feller A559 terminal 30g-f was switched off why is this happening ? Now in the cold season I have no power at all at the beginning, only when I drive for a while power is there again. Turbo servomotor new, intake hose to air filter box new, pressure sensor new, camshaft camshaft sensor new, all vacuum hoses new, charge air hose to turbo new, service done 8 months ago with all filters changed, a new intake manifold is installed, auxiliary water pump is reinstalled, boost pressure sensor is new, boost pressure temperature sensor is new. Oil pressure switch + oil temperature sensor is new, unfortunately I don't know where exactly they are located, I can't find it on the internet with pictures either.

Hello Mani39, Check the battery condition and connections, especially in cold weather when battery performance can decrease. Also, verify all electrical connections and grounds for issues. Consider using a diagnostic tool to scan for fault codes and consult a specialist if necessary. Let me know if this resolves the problem or if you need further assistance.
