Poor mpg, low temp

I've noticed my mpg has got pretty poor, around the low 30s and my temperature gauge sits a bar sometimes two below the halfway that 1*2s always sit at.

Is this a fault thermostat, CTS or both/neither?

I used to get high 30s even 40 on my 20 mile work commute, no town driving. My ph1 was even better

Do you get heat in the car? I would say a sensor.
Yeah I'm getting heat, I'm going to use it for a sneaky few days away in Snowdonia so it will be interesting to see what mpg I get on that run. The thing that I noticed first was the needle below half way, all 1*2s I've had were bang in halfway

I remember changing one on my Valver years ago because it wouldnt run properly from cold

if you’re using a Bluetooth obd with the torque app you can read coolant temps.

I would side on it being a stuck open thermostat personally.
Might get a bluetooth obd reader then, any recommendations?

@DomP182 but then if you do a long run over a weekend and get low MPG, surely you would save most the cost of the parts in using less fuel???
That's a good point but it's the 172 or our Tiguan up to Snowdon, I cant resist a blast up there in my car. The thermostat/Cts can wait

Got the bluetooth obd reader and downloaded Torque lite. Fair to say I dont understand a lot of the readings it gives or their relevance. Is there a guide anywhere as to what they should all be?

I can see it will be useful though, how accurate is the mpg average etc?

On the home screen, go on Realtime Information.

Mine loads up a page with dials on by default it has things like RPM, throttle and coolant temp.

Do yours look similar?

On my phone there is no home screen of preloaded dials, I had to put my own on. Also cant see realtime information, should I get torque pro instead

Could be different, mine is the pro
