Unfortunately, the driver probably won’t notice anything until it's already too late. That being said, if the thermostat fails when the engine is cool, the vehicle runs a pretty good chance of overheating. It depends on what position the thermostat was in at the time of its failure. Conversely, it could be showing a lower temperature than normal. Aside from the Check Engine light coming on, you may notice that your vehicle’s temperature gauge is reading abnormally high. This is pretty rare, though, so it would be wise to exhaust other possibilities before checking it.įor the most part, code P0597 probably won’t cause any noticeable symptoms. There is also a chance that the engine management computer – the Motronic – has failed. The wiring harness between the thermostat has shorted or is open.However, more often than not, you’ll find that it was stored because of an issue with the electrical connector.

The problem behind P0597 could be a number of things. P0597 are used by German manufacturers like Mercedes, BMW, Volkswagen, Mini, Jaguar and Opel. The only difference between these three pertains to the make and model of the car. This thermostat is used to monitor the temperature of the engine and make adjustments to ensure it doesn’t overheat or suffer from other possible problems. The control circuit is most likely either open or short. If a PCM (Powertrain Control Module) stores this code, it’s because the engine’s thermostat is experiencing an issue with the control voltage. The P0597 trouble code signifies that a thermostat heater control circuit is open.
