Once again my B5 has gone into a dead lock mode. Think i pressed lock button twice with doors open now it is in dead lock. The remote not working the key only opens divers door. the inside lock unlock not working. No sound in boot from pump. The interior light not working when door is opened. And when you switch off after a drive the interior lights not coming on as they once did. Tried all the resync thing not working. This has happened before and a VW audi garage did some thing and everything came back to life. This last happened about a year ago. Does anyone know what to do to sort it out?
