What is normal reading for the water coolant teperature gauge for GLA 180 Urban model
The gauge is reading nearly ninety, the car was new on 1st Marcg 2019.
Warm, the temperature should be 195 degrees Fahrenheit to 210 degrees. Ninety is way too low and is probably a defect in the gauge or sending unit. The car's under warranty and you should have the dealer fix it.
