Radio Signal Poor

[ValleysC4]

Hi any idea how to solve this?? I've ordered a new ariel to see if that works but saw online that the antenna base could need replacing? Is this easy enough to do yourself and how much are they? Noticed once that water was actually dripping into the rear passenger light on car ceiling so I'm guessing it's not sealed properly??

Try the aerial first, at only about £3 from a dealer it is worth a try but make sure it is the correct one since there are a few different ones. According to the Haynes manual for the 2004 to 2010 C4, to replace the aerial base needs the rear roof light removing and then the base nut undoing. The wiring then needs tracing to the pillar. When the base is put back I would use some sealant to stop rain getting in the car.
