  1. The first thing to do is check the battery voltage when the light comes on 
    e.g. is it overcharging (above 14.5 volts maximum) when it goes above 2000 rpm
    If so, then maybe the wrong alternator
    If not then check all earths to the engine are in place and not disconnected or broken.

    Otherwise last thing would be to check the over-running pulley is working okay (eg. only rotating one way and locking the other direction. If not then replace it with a new one

  2. Oh goodness that is a mixed bunch of faults

    As you say, my first thoughts were wiring issues.
    I would start at the battery terminals and leads including the all important earth leads and connections and go from there.
    If you can get it running then do a 'wiggle test' which is wiggling any wires and connections to invoke the fault and bingo there is your problem area

    Let us know what you find

  3. I would be tempted to read any fault codes to find the exact cause of the error and resulting light showing

    It could be non-related and worth checking to see if it is a coding issue which may be possible to code into the vehicle using the correct equipment

  4. Hi

    You are correct that the headlights need to deflect to the other side of the road

    However, you do not state the age of your Passat but if it is new enough to have HID or adaptive headlamps then these do not need adjusting as the beam does not kick up to the kerbside

    Otherwise, if you are in doubt then line the front of the car up against a wall at night and see if there is a kick-up in the beam to the nearside and if so you could put black insulation tape on the headlights by covering the kick-up and look at the results as you do it to get an idea of correct position

    I go to France every year for the Le Mans 24 Hours race week and the French police are really hot on British cars so they can increase their revenue for a week.
    Generally, we don't tend to drive at night and so it's not so important about the correct positioning of the black tape. However, it fools the police that you have black tape on the headlights (due diligence and all that) but they would have no way of measuring and accurately aligning the lights at the roadside 🙂 

    Enjoy your road trip 

  5. It sounds like the Airbag light is a coincidence and not related to the lighting fault you have

    Check the bulb is not defective (even if new) and then look at any earth points in and around the area of the headlight assembly

    Check also it is the correct type of bulb as well
