20 Most Recent 2003 BMW Z4 Questions & Answers


You can fiddle with thiis and check oil pressures but best is sump off, thorough clean, teardown the pump thoroughly clean it and pickup and replace it if any wear or the pressure releif spring is weak.You have given no mileage and no information on the oil used nor whether in a really hot area or 'where'?..there are several considerations ranging even into worn bearings...Of course with acceleration motor speed increases oil pressure...that's why light goes out (unlikely but possible the sender unit is faulty...but try replacement of that first if you want...) It doesn't take a lot of pump wear to cavitiate and drop oil pressures.

I would not drive the car until the problem is fixed as the engine will over heat an seize up. You may have a leaking radiator hose or heater hose which you can fix with little trouble. Put water in the engine start it up and look for the leak.

The direct answer is there is a z shaped tool that comes in the tool kit in your trunk. This is a hex ended key that will fit in the motor. Access the motor is also in your user Guide. In the center of roof near the rear view mirror is an access panel to motor area. pry lose the panel and access motor. Place wrench in motor and wind away. There should be a direct arrow noting the direction of rotation. Note this will take sever thousand rotations of the wrench, it is a slow process but works.

If sounds like the window came off the window track & when it gets halfway up the window motor may start grinding. 1st try lubing the rubber window seals w/ white grease to see if that helps . if not remove the inner door cover & ck to see if the glass is firmly sealed to the track & lube all gears & motor gears . If window is out of the track a SPECIFIC ADHESIVE GLUE is made for it. Reset it in the track & re glue it in position .Don't forget to lude the edges & seals. GOOD LUCK, Frank M

If it's like my 2006 Z4 key you don't replace the battery. It has an internal rechargeable battery that charges when the key is in the ignition. Not sure how to replace the battery if it won't charge.

There is one motor driving both wiper arms. If one side has stopped and the other side still works, it is likely that the point there the are connects to the drive is stripped or slipped off. Check at the point where the driver side wiper arm is attached to the drive / pivot point

Have your cooling system pressure tested. You might check for coolant in your oil, possible seepage of head gaskets. You don't see steam or white smoke from exhaust do you?
