Oh god I'm in motors, Wonder if anyone can help me, this last weekend whilst out I was caught in a flash flood in Notts (it literally came at us like a river). Upon reaching home the car alarm has gone very very quiet, you can barely hear it at all, i've had the wife's hair-dryer on it but to be honest It sounds/looks like the siren has gone. its an M series Sigma with immobiliser which I assume makes it an M30 ? Does anyone know of anywhere that sells replacements for them, or is water ingress repairable ? many thanks in advance, oh its in an old Golf TDI if that makes any difference. Regards LOAM.
