this can be a big problem so will start on easiest first. and try to repair as going, the passenger door the problem with this could be the solenoid for the door lock. and or the switches in the lock. driver door has the same but is the master door. ie if you open door from unlocking at pass door it will only open this door, drivers side will open all doors. flashing hazards this could be because the alarm is not completely turned off this could be because of the doors, mainly the drivers side. try to find the fault with the door lock and get back to me when you have found the fault. you will need a meter to check for volts and the switches, check them as lock unlock from the inside and the key to make sure they working. dpd spray should be able to clean them if you can spray into the lock and housing that is plastic. give a good flush out after its working wipe up the mess from the spray and mear grease on the lock moving parts.

The trafficator flash can that clicks and flashes the turn indicator lamps maybe faulty or the trafficator fuse is faulty.
To test the flasher press the hazard warning switch on and if the warning lights do not turn on then the fault is the trafficator can or the fuse is faulty.

Most likely needs to be re matched to the car.

1. Place key in ignition lock and turn to position 2 [all ignition lights on]
2: Turn key to off position and remove from ignition.
3. Within 10 seconds:
3a: press the Close [Lock] button and hold it down
3b: while the Close button is still depressed simultaneously press the Open [Unlock] button. Press and release the Open button 5 times [still holding the Close button down]
3c: Release both the Close and the Open buttons at the same time, and immediately push any of the two Open buttons once [i.e. either the Open doors or the Open Tailgate]

This information is for the resetting of a previously synchronised key to match the security system after batteries have been removed or replaced. This information does not work with new keys which it seems must be taken to a person with a key synchronisation device [or a super-ripoff-expensive MB dealer]

hope this helps
