Audi Q7 2007 MMI not working
Sunroof was open mistakenly and too much water inside.
MMI navigation stereo was not working . Cd changer was working without sound. I replaced the control board ( it’s 30$ on ebay) still not working. After removing main battery ports under driver seat , one time for 5 min MMI works but stopped again. After that with battery removal didnot run also. I removed the amplifier and all trunk fuses and installed after some minutes now MMI working .
Sun Heat help all connectors get better.
Steam cleaner make ports worst
Audi Q7 premium MMI multimedia system navigation back camera.
My trunk lock still not opening but I can close it with its botton, also trailer electricity not working , all ports are 4-5 volts with frequency.
If some one know something please help.
Thanks
