I have problem with my MMI panel in Audi Q7 2006. E380 -It looks like is broken(panel start to be crazy from time to time my whole audio system is bloked-VCDS gave me alarm about communication problem between all modules- I need to open/disconnect E380 and connect again communication start to work again, but only for couple hours.
My original part it is 4L0919609 I get some second hand unit 4L0919610 But When connect this new part my VCDS show me alarm about problem with communication with E380. Problem is only with comunication between E380 and module. CAn you send info about compatibility this 2 parts.? maybe there is some adaptation procedure?
