my gas guage usually sits at empty, but sometimes starts going wild, and ocassionally sits where it should... how can I fix this, new guages?
and they day I bought the car, the horn worked fine, but now it doesnt. only thing ive done to the car besides put a new battery in and fill it with coolant was put the rear defroster fuse in the fuel pump fuse to get it home *i have since put one in its place* how can I test my horn relay? I gotta get it back to pass safety.

also, there is a mystery light that keeps comming on, what is this?

edit: Unrelated but WTF is up with that gas guage? R means refill or something? and why is 1/2 off center? lol

That is your brake lining light. When that stays on all the time your front brakes have tripped the sensor and need to be replaced.

I don't know why 1/2 is off center but "R" is Reserve.

oh sweet.

so it flickering isnt going to kill me right? haha. im just makin sure its not a check engine light or something

Your gas gauge is probably jumping around because the fuel level sender is old and tired, replace and it will most likely go away. R means reserve, and the red light in that portion of the fuel gauge will light up when you get that low, it could mean "you should REALLY fill up"

hope that helps

wow, i never noticed theres a low fuel light... it hasnt come on before lol. is the sending unit in the tank? How hard/expensive is that?

With the gas tank I have a question for you guys that really know your Bimmers. The tank in the 325e is supposedly 55 liters. However, I hit the "R" and then refuel. But I only put in 40-45 liters until it is absoutely full again. The low fuel light has never come on (might be burnt out, but I doubt it) so where have the other 10 liters of fuel gone? Are they even there? I would be tempted to test it out to see how much further I could drive but running out of gas on the highway isn't all that high on my list of fun things to do. Fuel tanks.....baaahhh!

The 1/2 is off center because of the shape of the fuel tank makes the rate it lowers uneven. So ti be accurate they move the 1/2 mark

i have found the same problem with my 323i. by the time the fuel light has been on for a couple of drives i go to fill it up but it only takes 45 litres (out of 55). so 10 litres left -for my fuel economy that equates to about 100kms (roughly 65 miles?). maybe bmw has set a fairly conservative low fuel warning to stop people from running out?
