2015 GLA 250 Error Code P0597 Thermostat Fault
Just purchased a 2015 GLA 250 ("Edition 1" model), 84,000 miles. I am located in the Kansas City area. It came with a couple of fault codes, one of which is P0597 "The coolant thermostat has an electrical fault or open circuit."
I did a pretty extensive online search, but found no previous threads with any significant information on the forums. I found some general advice stating that German manufacturers typically build a heating element into their thermostats. The P0597 may simply mean that the electrical plug has corrosion, is not seated properly or there could be a broken wire. Or, it could be that the thermostat itself is faulty.
Looking on YouTube, it appears the thermostat resides below the intake, on the backside of the engine next to the firewall (at least that's where it's at on a CLA 250, so figured it must be the same for a GLA 250). Looks difficult to get to. I do have a 4-post lift, so I can get the vehicle up in the air.
Looking for suggestions or tips before I dive into the troubleshooting process. I will update this thread as I go, so hopefully it's helpful to others in the future.
