VW Golf Mk4 Fitting Headlight Bulb

One of the first jobs of winter is needing to replace your headlight bulbs, for some reason they seem to fail as autumn falls! I put this video together to show how to replace the headlight bulb in a MK4 VW Golf and to fit a new H7 bulb in the car. One side is easier than the other and needs less parts removed to access the bulb.

VW Golf Dash Display Coolant Temperature Fault - Thermostat or Sender?

When I bought my MK4 VW Golf TDI the temperature display on the dashboard was faulty and the needle wasn't moving at all. This is a sign that the temperature sender plug is broken so one of the first jobs I did was to replace it.

This then got the coolant display working again but the needle never got above the 70 mark on the dashboard display so it seemed there was another fault. On further investigation it was apparent that the thermostat was probably faulty too but originally masked by the temperature sender being broken.

Once the thermostat was replaced the temperature display started working again properly and as soon as the coolant was up to temperature the dash display rose to 90 mark and stayed there.
