Title: Which Thermostat
Post by: Gary on December 20, 2016, 07:23:50 pm

Folks, I've had a look but I'm still. Ot sure which thermostat I require.

The symptoms:

Car even after driving for upto 2 hours will show a steady 75degrees odd on the display, it will only ever display 90 when I am slow moving stop, start traffic.

I know it needs replaced but is this the main thermostat or the inline thermostat?

It's a 2007 Edition 30 with a manual gearbox, any help is much appreciated.

Mine is a manual 2007 Ed30 as well and there is only 1 thermostat on this car / model year.

So a new Thermostat didn't fix the issue, did a bit more digging and found that the coolant sensor may be at fault, anyone else tried this?

I'm pretty sure a coolant sensor will throw up a code.

No these stupid vag cars don't always throw up a code for the temp sensor  :doh:

Does the heat blast out like burning your hand type of heat?. Mine does now but that's because I've messed with the stat.

It certainly seems to heat up quicker anyway which is nice at this time of the year.
