Something wrong - unless you only drive to and from the paper shop

I get 20 mpg from my auto Baur with aircon

and 27mpg from my manual cabby with no aircon


both figures average of around town and A/B roads

You need some one to have a look at it.

Give it a good service and if it's still shocking, check out the operation of the blue temperature sensor. Having said that I get about 18 on the OBC doing short journeys in the countryside.

As above, the blue temp sensor could be worth checking out.

I changed mine on my m40 318i as it used almost £20 of fuel traveling 35 miles! I now runs much better!
Parts needed:

M40/M20 ignition coil with high voltage lead

the blue temp sensor is on top of the thermostat housing at the front of the engine. It tells the ECU how much fuel to put in based on engine temp. If it reads incorrectly it will put too much fuel in. They're cheap to buy.

Can anyone suggest how to test if the boot lights are staying on with the boot shut?

Looks like that but the pic is upsidedown.

Theres a brown one next to it on the top at the front of the engine.

20-21mpg. . . if that was all driven carefully then it is too low. . .
