Fuse #89 is missing in my 2010 BMW 128i. The check engine light never came on,(bought the car used) would that be the cause?

    The engine symbol light should come on at Startup but doesn't. Could it be fuse 89 since it's missing?

That fuse is for the secondary air pump which injects air on cold start up to help reduce emissions. Because it is cold emissions are not monitored the same way as when it’s warmed up so it may not trigger and engine light. My guess is that it was removed because it may have shorted causing the fuse to blow or causing a drain on the battery. I would either repair the pump or leave it the way it is.

If the check engine light never came on... what’s the problem.? Is the car not running.? Not running right.? A lot of cars have fuse boxes with an empty spot for a fuse. If you own a car without electric windows... and the factory makes a model like yours, that comes off the line with electric windows, then that spot may be used for that car that has electric windows.

SOURCE: battary light on , engine cut off car won't crank

sounds like it's your alternator, your alternator charges your battery and runs car once it is started. if you have a bad alternator your battery light will come on, and shortly after your vehicle will die, unable to restart without a jump. I would take your battery to autozone or an auto shop to have your battery and alternator tested.

SOURCE: check engine light is on 2002 taurus SEL DOHC

it could have been running bad with the bad plugs. reset the computer and see if the light comes back on. you may have already fixed it. to reset the computer take the positive cable from the car off the battery and give it 3-5min to discharge then touch the positive cable from the car to the negative cable (still attached to the battery) for about 5 seconds and then hook back up the positive post and that will reset the computer.

SOURCE: Check Engine light on 1998 BMW Z3 roadster

yes the light is because of the gas cap being gone (sets code in evaporative emissions system), replace the gas cap, disconnect the battery for five minutes and that will turn of/reset the light, make sure u have the radio code before u do this, if u don't u will have no radio after the battery is disconnected..

SOURCE: Check Engine light

try not to use high test gas. see what happens. sometime it can cause a ping in the engine and the knock sensor will pick it up and throw a code. let us know. try this first

BMW 128 CHECK ENGINE LIGHT ON

My wife's Honda CR-V has the "Check Engine" light come on every 7,500 miles telling you to get the oil changed. (It has no way of telling if it's been done or not.)

There are instructions in the Owner's Manual on how to reset it yourself...

Bmw 135i crank but dont start

it may have an engine immobiliser fitted, just a thought as I cant see why removing a fuse would cause those problems. I would be ringing the BMW dealer that you bought the car from as they may be able to help you without charging you an arm and a leg for something simple that you can fix yourself.

2010 jeep grand cherokee laredo fog lights

If it didn't come with fog lights, it may also have not included a fog light relay and/or fuse. Check the owner's manual for fuse and relay locations, and then check if the necessary parts are there.

95 bmw 525i no dash lights no tach no tremp gauge and fuel gauge pegged way past full

Why was the battery missing to begin with? I would start by checking all fuses under dash and Central hub. Check for burned in-line fuses,if any, coming off of battery cables.
