Technical EML and coolant gauge dropped

[zippeyrude]

An odd one today...

I was driving a country lane, after some mild motorway driving.

EML appears and i noticed that the coolant gauge was at zero (or even below the min mark).

I pulled over and concerned that i had sprung a leak wanted to see if there was coolant etc. I removed the rad / top up cap and was able to add a small amount of coolant (maybe 1/4 litre).

On checking the igntion, the coolant gauge was working again.

I was obviously concerned that id lost all coolant and risking overheating issues etc., but this didnt seem to be the case.

The thermostat needs replacing as it takes ages to get up to temp and motorway driving shows temp at 1/4 on the gauge, with parked idling allowing it to get to the half way mark (and nit more).

I checked the EML code and think it was P0116 which relates to coolant circuit. Electrical? (silly me cleared the code without jotting it down).

Light is now cleared / extinguished but id like to check and see if there is an issue.

Where should i start looking?

I think all will be well with a new thermostat. You'll have a new sensor and probably new coolant as well afterwards.

If it was p0115

when the weather get cold we get loads of cooling issues heaters only blowing warm P0115 error radiator fans coming on fast. gauge dropping down occationly. gauge only going up 1/4 way 90% are down to a missing rubber gasket inside the thermostat. Because the thermostat is opening and...

In my experience with a dodgy thermostat, if the coolant temp drops to 60ºC while driving it'll throw an EML, but will reset with a restart.
