How can check the s pass status check the passport number?

Make a soft reset.. By unpluging the battery when the phone is on..

Check the door switch operation.

Old new beetle VW harness has contact resistance problems(vibration of wires) and needs to be recrimped the long wires(vibration can be stopped by silicone rubber anchoring). Cold weather make battery voltages low and needs recharged with handbrake on(headlamps off) 10 minutes warming engine up the whole winter.

Sounds like the battery is weak. If it is older, replace it. If the module is bad it would'nt start at all.

My best guess without being able to see the car is that the battery hard wiring is faulty.

You need to check both the condition, routing and security of the battery negative and positive leads.
You also need to check the security and condition of any additional earth leads which connect the engine to the chassis/body.

you will need to find out if the battery is being charged when the motor is running.if it isnt you will have to check wiring from the charging system.There could be a problem with the regulator/rectifier unit.

You have to charge the batteries for nearly 8-10 hours. Brand new batteries also require a full recharge of 8-10 hours.Not only making sure the batteries are charged, have you changed the battery in the menu under type of batteries.

Check on the utility tray where your charger cord plugs into the rear of the chair it should be on the far left side of the tray near the amp meter Hope this helps
