High pitched / crackling noice inside car cabin

I own a 2010 328i Xdrive, 4dr. Upon entering the car I hear a crackling, humming noice coming from the dashboard. Upon starting the engine I hear a high pitched noice, like a whistle, also coming from the dashboard or speakers?  This noice is there as long as the motor runs. When I shut off the engine and remove the key fob the first noice stays for a while longer until I hear like a shut off of sorts. Then the car is quite. When I open the door that noice comes back. Has anyone got a clue about it? BMW dealer wants to charge 350 $ for diagnostic alone.  It’s literally driving me crazy. Thank you for any suggestions. Dominique.

Check the TCU Bluetooth unit or get it checked. You should be able to find a BMW Specialist near you (I take it your in the USA) they will be more sensibly priced and have all the knowledge/tools. Check www.pelicanparts.com talk to them if they are far away good website with lots of help.

      E53 petrol fail safe again.

      Morning Stu Long time since I played with a straight six so the old memory might be wonky here so check realoem From memory it is linked to the Air Pump and Vacuum control system. Find the Airpump and follow the Vac lines to the rear of the engine you should find a valve with a plug on top (or end) first make sure all lines are good no splits or cracks check the valve is operating, dont forget there is a non return vale in the system close to the inlet manifold. Hope this helps Dave

      Water leak at sharkfin aerial

      Morning Vic New one to me but I guess anywhere there is a joint is suspect. Like the seals around the rear lights that suddenly start to leak, removing them a good clean and renewing the seals seems to work. Check www.realoem.com to see what is fitted and how Dave

      Rough idle problem

      Morning Billy When was the car last serviced ? The symptoms you describe could be due to an air or vacuum leak, old hoses seals and vacuum lines can start to crack when cold they are stiff and don't leak (as much) when hot and flexible you see the issue developing. Your OBD Scanner needs to be BMW capable a standard scanner will only see critical functions. Dave

      Rough idle problem

      Looking for some help. 2010 116i M sport with the 2.0na engine. When cold, car ticks over perfectly. After about 15 mins of driving when idling you can feel it getting a little bit rough. Nothing too bad, but the longer you idle the worse it gets. No EML. When running car runs perfectly not a flicker. Today left it idling for 10mins after I felt it and then revs started to fluctuate but still no eml. OBD scanner can’t pick anything up. Turned it off and back on and was still rough but only a little bit like when it just starts. Anyone had anything similar or can point me in a direction of where I should start looking?
