Well, i read on here that poor radio signal mostly comes with poor distance remote unlocking, but my fob works from at least 21 metres, i checked.
Fuses also checked, but nothing blown
I checked out tutorials , but i dont seem to have the same model where access to the Div Amp seems quite easy on most video tutorials. Prize out 4 rubber bungs, then undo the 4 Torx bolts, carefully lift spoiler, and there there's the amp.
Mine looks like the photos below, and there doesnt appear to be a way in , using the above method. That black metal surround which runs across the top and up both sides appears to have no bolt access ..unless i'm missing them, but i dont see any way to get behind it
