A few days ago the instrument cluster leds started flashing but when starting the engine sometimes it goes away and sometimes it stays about 10 seconds and then it stops flashing and the reverse light stopped working, i checked the fuses all is ok and the battery is new installed few months ago . This is the first time it happens so what could be the problem!!! I took a video and here is the link on youtube :
