Hi all i have some questions about my a5 s-line, owned it for about 6 months within a month of owning it the engine management light came on so i took it back to the garage i bought it from and the said they hid fixed it, all god for about another 3 days then the light came back on, unfortunately by the time i had chance to get back to the garage the warranty had ran out, now the car is lunging intermittently like it is loosing power, its like a new warning appeary every day, i did question if this could be water ingress and checked the comfort convenience module and fuses in the right side of the boot and there was indeed some corrosion to 1 or 2 fuses, i am using a cheap foxwell scan tool to read and clear codes, has anyone had anything simmlar that coint me in the right direction please,
thanks in advance
