Hi all
I've noticed recently that my 55 plate mk5 gti 5dr has developed a bit of a thirst
Now it's never been particulary frugal, but my normal 30mpg av has dropped to around 25 over the same journey/conditions
Also, my radiator fan seems to come on at random times and the heaters not particulary hot
Someone mentioned this might be a fault of a temp sensor somewhere that's cause the engine to run rich and mess with the cooling system
Anyone shed any light on this please
Any help would be greatly appreciated
Cheers
Graeme
