2007 BMW X3 2.0D - Answered Questions & Fixed issues

Are these the original tires? I had the same problem with a BMW years ago with my first set of replacement tires. Turned out the wheels were porous, and the air was leaking through the wheels. We needed to put tubes in the tires. If all 4 are going down at the same rate, that may be it.

could just be key needs to be resynced, insert key in ignition, turn to on, remove, press/hold lock while pressing unlock 3 times quickly.

Assume you are asking about engine temperature. Possibly because when you turn the aircon on, additional electric fans are turned on to provide extra cooling. This helps when the system is heavily loaded in hot weather. If the weather is mild it could reduce engine temp slightly.

Mr. Williams. just take it to your mechanic who will fill it with watter and by using a radiator pressure test tool will immediately give you the answer and the cost of repair.

replace thermostat and the temp sensor on the housing.

almost sounds like the air tubing came lose behind or under the dash. reconnect the hoses.

Have you traced the hot wire up to the source to see where is loses voltage, you have to do that. You will need a 12 volt test light, about $5 at any auto parts store or sears.

possible causes are crankshaft position sensor cam shaft position sensor/s ignition control module broken timing belt/chain

If it is black sooty smoke injectors are putting to much fuel into the cylinders so they may need to be tested Whitish grey smoke could be extra oil burning due to busted cylinder rings or head gasket allowing coolant into cylinder

has any lights come on the dash. like engine light abs or a spanner light?

disconnect battery wait 5 min reconnect battery or take it to auto zone have them reset

I would suggest taking it to a shop... however if you have the means there is a plug on the transmission that you remove and if fluid drips out it is good if no fluid then add. There is no dipstick

how long does it take ? it can be the thermostat that is stuck open

You might have transmission problem. It could be low fluid level or could be an internal transmission failure. I suggest you to have the fluid level checked for quality. Another thing you can try to reset your transmission. BMW transmission would help you to know about the transmission better.

This will depend on the color of the smoke. A bluish color would indicate that you are burning oil. There may be bad oil seals somewhere in the engine. A common place where oil comes in is in the spark plug. Inspect the plugs for oil. Each of the holes for the plugs has rubber seals which prevents oil from entering. Have the plugs replaced if it has been fouled and the rings.
If it is a white color, it is antifreeze or radiator fluid that you are burning. Check the head gasket. If it is a black colored smoke, you are running rich. Try cleaning the intake with a electrical cleaner spray to clean out the MAF sensor. Check also if your O2 sensor has been disconnected.
At times the engine light does not turn on but there are cases that an error may have been detected in the past. It would also be a good idea to use a scanner to retrieve errors. Some shops would let you borrow one. If there is an error it would help us determine the problem accurately.

need fault code more info

The last post is correct, but I also have a few tips and pictures.

1. Open hood.
2. Use a small flat screwdriver to CAREFULLY pry open cap leading to the headlight. Start directly underneath the tab that says "V2." Be careful not to break the tabs! -- to do this simply push the small screwdriver under the, as you push it in, you will hear the clip release. The cap will pop and remove very easily after that.
3. Pull out wires, unplug burned out bulb - this clips in with what I can see is a spring clip. I reccomend using a cloth when removing and replacing the bulb. This will protect your hand if the bulb breaks by accident. Also some halogen bulbs will pop/break if your hands leave oily residue on the bulb. When the bulb heats, the oil heats too and can break the bulb.

jack the car up and spin the wheel listen to see if there is a droneing sound if so its a wheel bearing that needs to be replaced

sounds like a short between the mirror control wire and the passenger side unlock wire, probably the wires have rubbed trough the insulation, you have to locate the wires and put some insulation tape on the spot they have rubbed trough,

I'm sorry but i laughed in dismay when I read your problem. The dealer is an idiot clear and simple. It is perfectly reasonable for you to expect the handbrake to be disengaged if the indicator is off.
Yes it is quite possible to drive the car with the handbrake on but you would feel it no question. However if it was only slightly engaged there would indeed be some wear on the rear brakes. The handbrake has merely got a thin metal cable that runs underneath your car that splits into two separate cables which in turn connect to the rear left and right brakes. So there aren't any extra brakes for the handbrake just the ones which are on the rear wheels.

Of course the other thing is you may have a faulty handbrake indicator light. So it's not really about who's fault it is but where the fault lies on the car. I'd go and check out a local garage unless of course your car is still under warranty.
If it is go to another dealer and armed with the info above don't let them fool you
Good luck and i hope you get it sorted
