Hello guys,i bought an a3 8l 1.6 fl like a year ago and from the 1st day i got it it does a weird thing that after a lot of search on web didnt find any solution but i saw its a common type of problem,i have to mention i have already check the fuses x2 times,the ground points even under the drivers side dash,changed battery and even removed an installed alarm in order to stop power leak,nothing worked,when i power uo the car even if i dont start it my clock and trip reset to 0,if i let the key on the ignition even if its off the clock keeps working,the prob appears when i remove the key from the ignition,3-4 mins after i remove the key it reset it self,spend a lot of time on this so i would really appreciate if anyone knows a thing on it,thank you in advance guys !
