Hello! Everything started 2 years ago when my car started to show many errors ( pedestrian, brake , coolant, park assist, lights etc) . After this i replaced both batteries, cleaned CEM contacts and under carpet connection, the car worked fine for 6, 7 months and the errors came back for a few times and then stopped coming for a long time until 1 week ago when , after 400 km drive and while driving on the highway, came all the errors back starting with Pedestrian airbag service required, abs , brakes , lights , park assist, no speed , revs, temp on the dash etc ...the engine was working normally and the revs and coolant temp were coming and going from time to time ... I stopped the car and started again in a few minutes and the car was fine , error free for 2 days . Today and yesterday the car would not start ...all the errors were coming right after pressing the start button. After 5 minutes of trying the car started and i was able to drive to work . Now is the same ...all the errors are on the dash . Closest available time at the dealer is 15 August!!! I have vida and read all the errors ( maaany) and most of them are communication error or invalid messages received, or hi CAN something... Please help!
