DME 2EF4 after water pump and thermostat replacement.

So, about a month ago, I replaced my Water pump and thermostat.



No issues, all went well.

Drove approx 1500km on it and I get a SES light.

I was away from home... Like 1200km from home.

No performance issues or cooling/heating issues either.



But when I did get home, using DIS, I got DME 2EF4



I cleared it.

Drive another 300km and it SES came in again.... Same code. Today.



Shit, does this mean a new thermostat?

My parts are continental water pump and a quality After pump.
