Just a quick one
My car (Facelift 1.9 CDTi 150 SRi) has been running at 86-88 degrees when fully warmed up. In traffic it would rise to 90 and the fan would start up and bring it back to 86. Great, but todays hot weather, the temp guage ran up to 92 normal driving. I expected this with the outside temperature being 23 degrees. I then flipped the CD30 into test mode, and was shocked to see the temperature readout on there at 97 degrees . It went up to 98 (but guage only showed 92) and the fans kicked in and cooled it.
It seems as if the temp guage and CD70 are the same up until 86 degrees, then the guage rises slower than the CD70. Ie, the guage and the CD70 are on 86, then when the guage is on 92, the CD70 shows 98 degrees (when the fan takes over).
The thermostat was changed last year, and flushed the entire cooling system with a hosepipe until it ran clear, and refilled with fresh coolant. I've no coolant loss, no funny smells etc, and it always cools.
I have heard there can be differences between the two readings, but to this extent? And should I worry?
Anyone else had this?
Thanks
