Bmw x3 troubleshooting

SOURCE: lost keys require new locks for BMW X3

replacing the complete lock set with the EWS control unit can be expensive as the control unit will also need to be programed and/or encoded, however if the lost keys cannot be found and you are sure they cannot be used to steel you car you can just order replacement keys from your local bmw dealer. hope this is of some help. You will also nead to disable the lost keys if you order replacements rather than a complete set.

SOURCE: 1987 bmw 325 idles rough

I had a similar problem on a 318IS.
The rough idling was accompanied by an occasional whistling noise from the general engine area (caused by air leaks through the front and rear crankshaft oil seals).

The problem was caused by a faulty crankcase ventilation valve (Costs about $100).
The vent valve is easy to replace - (2 screws) - check the vacuum hose that connects this valve back to the tappet cover air vent nipple - it goes soggy and disintegrates.- replace with suitable oil resistant vacuum hose.
While on the job, clean the throttle body / butterfly valve internally with a soft toothbrush dipped in petrol. This cleans off sooty deposits - makes engine idle rpm more consistant.

SOURCE: HOW COULD I READ CHECK ENGINE CODE ON A 1986 BMW 325E???

You can't use a tool to pull codes from an '87 BMW 325(e). You have the 2.7 liter and your DME, or computer is a Motronic. If you had a 325i, then a tool could read the codes because the computer was upgraded that year to a Motronic 1.1 system with a round plug in under the screw cap on the driver's side under the hood. The only tool you can buy is the one for resetting the service interval light and resetting the oil change light. To answer your question about going about finding your driveability problem would be to get a BMW Bentley Manual. This manual shows you how to use a standard voltmeter to check everything from your computer plug in. Your computer is located above the glovebox.

Good Luck,

The battery could still be bad and if you don't have a totally good battery in the car it won't run right. Take to one of the parts stores and they can check it for you for free. Probably as simple as a battery.

It's essentially our "check engine" light.

Go to a local mechanic or auto parts supply store and have them read the diagnostic code on the OBD2 port. Auto parts stores usually do it for free. With the code in hand, they can look up the code to help diagnose your problem.

It can mean something as simple as the gas cap is not on tight to a serious malfunction. It's best to have the code read soon!
