Superb 1 2004 Hi..I have a big problem..no light in my interiors didn't shine in my car for a while..then another problem occurred..and the car sometimes couldn't be locked or unlocked..and the windows were hard to open..flashing up down..plus clock was reset and KM..after visiting the electrician found several errors..broken wiring under the carpet somewhere in the back of the seat..plus replaced the lock and microswitches in the door on the driver's side..more control unit in the driver's door and control unit in the right rear door..and the wiring in the driver's door bushing replaced..the comfort unit is fine..plus after disconnecting the non-genuine sony radio which has been there for 5 years so everything started to work even better..I took over the car..I drove 3 weeks without the radio until I decided to connect it..I connected..the everything worked until the next day..the problems the same..but the interior lighting works..it also tried the original car radio and the same problem..I disconnected the radio and still the problem persists..morning at five o'clock in the car and everything works..without the passenger window that went jerky up and down..and I'll go from work and the problem again..the windows problem again and reset time and the problem of locking ... windows and locks behave as im wanting..sever the lock works and the two windows go..you cross it crosswise..like if there was a weak current in the car..but the flashlight is not even 2 years old and the car starts on the shell..also I tried another battery
