1999 BMW 5 Series - Answered Questions & Fixed issues

if your filter has not been changed in a while and the quality of your fuel in your state is not that good I'll advice a fuel pump replacement , and before you do that if you have access to the pressure tester ,test if pressure is optimum.

Do a check on all the fuses look for crack in the fuse .But as all items that are faulty are on the indicator stalk i would think its inside the indicator arm .

check that the transmission oil is bright red if tan colored replace it with a service run the fault codes to check for servo/solenoid and TCM problems check for VSS unit

try to check connections inside the door, it probably problem, if you dont know how to reemove enterier, let the someone who know check that

check wiring where you was replacing items make sure everything you unplugged is back right and not melted to motor

I had that problem in my 2006 BMW 316i. The timing chain became slack which neccetated having it replaced at 67K miles. Engine was only driving at very low power because of this. Note; Oil had been changed at recommended times.

This is the classic symptom of a bad battery. Your engine requires a lot of power to crank but the little lights in your dash require very little. if the battery is even a little drained it won't crank the engine, but everything else will seem to work fine. Either jumpstart the car (if it starts, then you likely need a new battery) or test the voltage at the battery terminal when trying to start the car. If the voltage drops below 12 volts you need a new battery (or at least a freshly charged one)

check the power in your battery if low recharge it.

run by your nearest auto parts store. the can hook it up to a computer and get the error code and cross reference it and let you know exactly what the problem is. most stores offer this service free of charge, like autozone,orielys,advanced auto parts ect. hope this post is able to help you. good luck

Most probably its a low fuel pressure related problem.Get the fuel pressure checked.If its low then this is faulty fuel pump and clogged fuel filter issue.the other possibilities are,-----

A car that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also this problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt.If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced.If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the care. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the car. If it very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gage and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem.Thanks.Helpmech.

thats your ICU there is a fault in it get it reset

you can take you car to garage check the air condition,if you feel it's too trouble,you can get a car diagnostic tool check ari condition, this tool can Diagnosis of cooling electronic.

You will all have to re-enter the security code for your radio....If their is now power whatsoever to the unit, then I would suggest that you get an auto electrician to put a voltmeter on the unit to make sure that it is getting power or hasn't had a spike and cooked the chip inside. Check your MAIN fuses in the engine bay, not just the interior fuses, I would also strongly suggest to give your engine management system a re-boot as well, just to make sure.

This I believe on your description seems like it could be a sensor problem, like maybe the 02 sensor that is part of your emissions (Cadillac converter) I am disappointed that BMW did not see this come up on there codes, as it would of if they put it on computer. The fact that cut off, would have nothing to do with the breaks. And believe it or not, sometimes the sensor bad, will cause the other stuff mentioned to come on, and breaks could of been fine. Hope this helps,Mike.

SHOULD PLUG MEMORY SAVER IN THE CIGARETTE.THE BMW VECHICLES IF YOU DISCONNECT THE BATTERY YOU WILL LOSE MEMORY TO THE ECM, IHKA CLIMATE CONTROL MODULE, ZKEV CENTRAL BODY CONTROL MODULE WHICH CONTROL DOOR LOCKS, WINDSHIELD WIPERS AND WASHERS,ANTI THEFT SYSTEM, INTERIOR LIGHTS RADIO ALL THESE COMPONENTS HAS TO BE REPROGRAM USING A BMW SCAN TOOL.

First two most likely suspects: 1) A big crack in the air tube that runs from the air filter to the throttle body. 2) A failed mass airflow sensor.
You should get a check engine light which will store a trouble code. However, there is no trouble code for "massive air leak in the intake tube", so if that tube has cracked, the code will point to some related sensor or system.

Try turning the ignition on (not to turn the engine over but only on) for 5 seconds and then off then repeat that three or four times then try and start it. If it starts up immediately after that then you have a fuel pressure problem and by doing this you are priming up the high pressure fuel rail. possible causes are a fuel filter blockage, if you dont know the history of the fuel filter then replace it, or could be a pump issue or a pressure regulator on the rail issue.
