C Class. W204 P0128 error Coolant Thermstat
Hey guys. So I Got Error P0128 on my 2013 Mercedes C180 w204 face-lift. I had a diagnostics found out it could be faulty Thermostat or faulty ECT(Temperature sensor for Coolant)
So I cleared the error.... I have monitored the gauge while the error was on and after I cleared it.
There are no issues.
It warms up to optimal temperature just like it always has.
Left it overnight
Took it for a test drive.. It's cooling just fine..
The error has not come back
Bare in Mind we have been it was a unusually HOT day.
My QUESTIONS is this.
What could have happened and should I be concerned.??
Could it have just been a sensor malfunction.
It's not overheating??
And if it was really a should the engine light not come back on after my test drive this morning.
