Hi, 2003 Beetle / reset - clear faults

Im actually going through the process of fixing this problem with my car. the P2181 is a performance cooling error, usually brought up by thermostat, radiator issues, or ECT sensor. You should narrow it down and check both radiator and thermostat to prevent later issues. If all is well go to your local autozone, pep boys, checkers..etc. and have them erase the DTC error. If you are looking for a more long term solution you can purchase many different software such as VAG-COM or any other software used to run test on vehicals. Be sure you know what you are doing though because messing with your cars computer can have long term effects that can be pricey.
