Asked by Aug 09, 2013 at 03:35 PM about the 2003 Volkswagen Beetle

Question type: Maintenance & Repair

My CEL light is throwing a code of P 2181. Which is a heating or cooling issue. I have the
part store telling me it could be a sensor, a thermostat, or a water pump. Any ideas on where would be the best place to start.

I would start at the thermostat since that is the cheapest and easiest place to start and the coolant level sensor as well along with fresh coolant. Make shure you get the recommended coolant for your car and distilled water since you usually want a 50/50 mix. Then get you CEL reset and go from there.
