Temp Gauge dips when coming off accelerator

[iahobson]

Hi All,

I'm a first time poster so please go easy on me!!

I've been the proud owner of a FF182 since Feb but have experienced a few problems of late. The most recent is that the temp gauge dips from its mid point by approx 2 bars when I take my foot off the accelerator at high revs. It recovers again within a couple of seconds so I'm not too concerned by just wondered whether anyone else has experienced something similar?

Appreciate your help,
Ian

Thermostat needs changing

Coolant temperature sender. Get it fixed. It causes over fuelling.

one or both of the above ^^^ i did both when i had those symptoms

Thanks all for the quick responses, I will look into getting the two parts changed.

Roy - it is the sender that I need to change not the sensor?

 

[MartinR]

The thermostat and the CTS (coolant temp sensor) need to be changed

Thermostat costs around £19-£23

CTS is around £28 iirc

Plus coolant Type-d £12

When this happened to my car, it was just the temperature sender. More specifically, the wiring attached to it. Not sure why people are suggesting that it always fails alongside the thermostat.
