on board computer question

[alane]

my on board computer temperature always reads -22 degrees no matter what the temperature is ,other functions on the computer work fine any suggestions ?

your temperature sensor in the brake duct is either damaged/missing/disconnected i would think mate

[alane]

ok but excuse my ignorance im new to beemers where is the duct ?

[Dan318-is]

brake duct. look at the front of your car. should be on the lower valance. the right hand side one houses the sensor. it pops in through the top of the duct

thanks fella will have a look tomorrow

[alane]

update- had a look today cant find the duct or sensor -looked all along the inside of the front bumper and inside around the headlight area am i looking in the right place ?

it should be in the plastic duct on the passenger side of the car. the plastic duct is located right next to the foglight (or the blanking plate, if you dont have fogs)

My dad needs a new one his always reads -30

[alane]

had another look today didnt find any duct maybe its missing but i have found a loose plug not connected to anything i figure this may be it ,it was behind the left fog light .

[smithy318i]

do you want a set of ducts?

i have a set standard ones for sale

this sensor is pretty cheap on ebay........

The sensor is £5 from one of the internet e30 breakers. ebay can be dearer.

If you have no sensor maybe someone has retrofitted an OBC to your car and not bothered with the loom and sensor. It often happens. I suggest you find the sensor and check whether you have the loom before buying a new sensor.

no the obc was definately fitted at the factory its listed on the original invoice which i have in the history file .
