Thread: D2 TD5 Temp light - intermittent

Hi, if you have a nanocom or similar check the coolant temp input when this happens... if no diagnostic tool available check the cooant temp sensor's plug to be well connected eventually replace the sensor cos it's the first suspect, it's not expensive and if the problem remains it can be a bad contact or wiring issue along that circuit or within the instrument pack(the ECT sensor is connected to the ECU's black plug not the red one)

Hi and Thank you

I do not have a Nanocom / alternative handy and the nearest would be a distance away. I will certainly check out the coolant temp sensor plug connection and if needed replace the sensor.
I might check the ECU Black plug to be sure it's clean and fitted correctly as well.

will let you know the outcome

Thanks
cheers

So when the light comes on, the engine idle speed increases to 1000rpm?

If so, does it run ok or is it missing?

Hi
I only noticed the higher revs once and saw taco steady at 1000rpm and yes it was missing a bit. All othertimes it was normal revs and no miss.
bit of mystery
Thanks
