Recently ive been doing less mpg than i was last summer and the only thing that's changed is the cold weather. Could this be the cause and is anyone else having any similar trouble?
Thanks

It's normal to use more fuel in winter. Cold air = more oxygen = more fuel to keep the air:fuel ratio.

I thought so. Im only asking because its dropped down to about 26mpg whereas in the summer i was getting around 36mpg i thought it was a big drop
-
does seem a big drop, i get 35 odd mpg at the moment

It'll drop down but not by THAT much. You've certainly got problems somewhere. Try a new coolant temp sensor.

will try that thanks. I can tell any difference in performance at all so i wouldn't have thought anything major. Am i right in thinking this?

possibly, could be a number of things. faulty sensor, something clogged up etc, exhaust doesnt leak does it ? that can make a surprising drop

yes it does. It keeps coming loose and falling off between the cat and middle box

Exhaust will only affect MPG if the leak is BEFORE the lambda sensor, not after.
Try coolant temp sensor as it's a common issue. It runs with the "cold" map, so it still drives fine without you realizing anything.

will the temp gauge still read fine on the dashboard?

Yeah the coolant temp sensor is different to dash temp sensor.

i see. Where is the coolant temp sensor
-
I'm guessing you have an 8v? If so then it's on the front of the cylinder head, in the coolant flange, held on with a horseshoe clip. On the 16v it's screwed into the side (gearbox side) of the cylinder head, to the left (as you look directly towards it) of the side coolant flange.

Don't know why it's named intake air temperature sensor, because that's the coolant one. On the ECP website type your reg number and click Engine Parts > Fuel & Engine Management > Engine Management Sensors :smiley:
