What mpg are you guys getting? I think I have a duff sensor or something as I'm only getting 21mpg
It's a motorway cruising commute so it shouldn't be that bad, I was getting over 40mpg from my Libra and 50mpg from our passat tdi for comparison.
The only reference I've found was possibly a duff coolant sensor but I have checked the warm resistance and it is smack in the middle of specs, the supply voltage from the ECU was significantly down though, the ECU should be giving it 5V but it is barely over 1V measured out of the ECU, the sensor ground is fine. Is it possible part fo my ECU is knackered? The theory I am working on is that it is constantly running rich as it thinks it is always warming up. It drives fine.. Maybe I should chek the condition of the plugs too? They did mention the CO reading was near the max at the MOT..
Any suggestions gratefully received!
