Hi, put a post on a while back regarding no sound through any part of the sound system on my 2006 L322. Checked all the connections on all the ecu's in the rear left compartment all were good and clean. There is no sign of any damp or water ingress there either. What I did notice when checking all the fibre optic plugs was that the red light is flashing. Can anybody say if this is correct or should the red light in the fibre optic cables be constant? With all the connections being good and the touchscreen display in the cabin showing that radio stations are able to be changed, the cd will change disc/play as normal and the sat nav working correct I am thinking the problem lies with the Amp at the bottom of the rear left compartment. Getting frustrated with no sound and would like anybody's thoughts on buying another Amp. Don't want to send money down the drain if someone else knows of this problem. Cheers.

My 2004 L322 loses Radio sound aBout every six months. The head unit appears to work, but there’s just no sound. I change one of the fuses in the glovebox and then it works again.

I’m afraid I can’t tell you which fuse because my L322 is away at the garage for some work. When I get it back, I can check which fuse it is.

All the best
