Nope. It was still kinda working as it should, just sticking a tiny bit open so the car was about 10 degrees cooler than it should be. Feels much better now.

Part was about £30 from VW, and fitting (inc coolant change) was £200. Ball-ache of a job. I attempted it but gave up.

I seem to have an issue on dash mine is always 90 but with climate 19/2 I only seem to get over 80 in traffic or sitting at 70 on motorway normal driving I always seem to be around 70 is is this correct?

^ sounds similar to my problem. Gauge showing 90 apart from coasting down hill but climate display was showing around 74 in normal driving. When dash gauge dropped 1 notch, climate would show 71 degrees.

I'll try a drive tomorrow and check again  but sounds like I'll need to replace my thermostat then

What would be good is a video of the cruise control temp video from a cold start to 10 min in on average driving, prob find some have an issue and didn't know

Since changing mine it has not fluctuated to a low level, and I have been running wih the MFA add-on via FISCON to get oil and water readings whilst driving.

I wouldn't like to guess at how many of these stats have now failed and we are just realising.

think I'm in the same boat.  Sits at 90 when sitting in traffic, once I get on to the motorway etc it drops to 70.

VW Quoted £200 all in with a courtesy car :).

Local Indy is £100 labour plus I have to source the part.

AwesomeGTI seem to be a bit of a rip sometimes.

As I said further up in this thread, I attempted It but it was just too tough 

Most of the front of the engine has to come off. I got Awesome GTI to fit it in the end

It was the main one (in part number above)
