E30 Zone

i am currently getting 15 mpg from my 325i if im lucky in this cold weather, i also live in the sticks is this common!!!

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

Oo thats bad.
My 325 cab does about 30 on a run & 22 around town.
You need some one to have a look at it.
Best of luck

just a quick suggestion, my 320 was struggling at 18-20 mpg befor i gave it some new oil and filter, now its doing about 30

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!

whats a blue temp sensor and where is it, how much a the

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.

according to the obc i get 27 with 50/50 town and motorway

mine is showing around 23 around town.

the othere day i got 28 mile on £15 where do i get this sensor!!!

anyone put me a picture of this sensor please

Looks like that but the pic is upsidedown.

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

new all time record 80 miles on £20!!!!

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

i get 15 mpg even thou i changed suspension to eibach and b8 shocks, full service, brown and blue sensors... whats going on ???

my obc was changing from 36mpg then down to 22, 21, then went to 10 now its at 15mpg...whats going on ????

Most i have got on the OBC is 27 MPG and that was on the motorway for around half hour. Is this normal?
