It's a chain, it's a TDI so I doubt it would be an issue with this. It's also extremely intermitent and only on hills it seems whereas I would suspect the chain slipping would be much more often and more catastrophic! I checked yesterday and it hasn't lost any fluid so I doubt it has a leak or is losing pressure. It does- I can't see a sillica pack in there so this could be the culprit. I assume this would require a full coolant system flush? Yeah and this could also be a factor, I live at the bottom of a valley so the engine is perhaps being strained too quickly by going uphill before it has time to kick in the pump/fan. From the sounds of it, I think it may be time for a garage to have a look at!

sorry! 1.6 TDI, c60k miles. Based in the UK so it started happening during a recent heatwave c30 Degrees C but it also happened yesterday when it was only around 23. After the second time it happened, I checked the reservoir and it was a little low (just below the min line) so topped it up with coolant to near the max. I thought that the low level was the cause and was hoping filling would have resolved it. I will check again if any has leaked but I can't attest to the quality of the stuff that was in there before as that was the previous owner. It might be that it's been topped up with water but it looked the same shade of pink.

Hi All, Keep getting the "overheating- Turn off engine" warning and guage shooting up to 120 on the dash when going up a hill but it quickly returns to normal when the car is level again. I've had the car for around 8 months now and over many hills and long miles, i've not had the issue at all. I know it's been warmer recently but I can't fathom why it suddenly shoots the temp up. I notice that there is a sensor on the top & back of the coolant reservoir so perhaps it's getting splashed with hot liquid on a hill? perhaps just a faulty sensor or air lock? or something to get a garage invloved, water pump etc? Anyone experienced something similar?
