BMW 5-Series Maintenance and Repair



  • Same thing is happening to me now. How did you fix it.

    I find that the motion sensor built into the BMW factory alarm on my E39 is hair-trigger sensitive, a passing breeze can set it off if the roof is open.

    The solution is to either close the sunroof or double click the LOCK button, this turns the motion sensor off. I've even set it off by standing next to the car w/o touching it!
  • Thanks a bunch. I double clicked the lock button and it worked.

    On another note, on the same 2003 530i, upon tuning the key in the morning, the motor turns over fine, but I hear a slight spinning sound like a loose belt or pulley after it turns over.

    The dealer replicated it once during service, but could not sustain the sound long enough to determine the cause. Now I am hearing it a little more frequently.

    Any ideas?
  • Actually doubleclicking didn't work after all and I took the car to the dealer.

    They found a defective sensor under the hood. They also found a leaky antifreeze tank.

    This is my third BMW and they are like dating high maintenance women.

    The car: 2002 530 5-speed SP, PP
    Current Mileage: 75K

    I intend to keep the car for at least 2 more years. These past few years I've been averaging about 8K miles per year. Had Inspection II performed at 58K and oil changed again at 68K. Do I wait for dash computer to tell me that next inspection is due, or do I perform preventative maintenance now. If answer is preventative maintence, is that just Inspection I again or is there more involved. I wanted to get info here before I call the dealer or go to an independent shop.

    I'm about 99% sure that the 75K is just an oil service... Inspection I comes again at 90K...

  • 2 months ago I replaced the radiator, tank, upper and lower hoses, and replaced the thermostat. 2 weeks ago after driving approx. 120 miles on freeway I stopped and upon restart the gauge went into the red. I let the car sit for 3-4 hours and then topped of the coolant with less than a pint of water. Was the able to drive approx. 5 miles with no overheating. Trailered the car home and had the fan clutch replaced as well as the bleeder valve which had a small leak, and another thermostat. Drove in city for 2 days and then it overheated again. Mechanic suggested burping the system to remove any air bubbles. There are no indications that would suggest a head gasket problem. The water pump is working. The thing still overheats. I'm into this for over $1000 now. At this point the car is just sitting. Any suggestions would be appreciated. In other words what else can I try before giving up and taking it to the dealership.
  • Yes you could have air in the system, so I'd have the mechanic do that procedure of bleeding the cooling system. A head gasket would be a much faster overheat than you are experiencing but I'd have the coolant checked for combustion gases nonetheless.

    If you bleed it, and check for combustion gases and it still overheats---well, then maybe the water pump needs to come out and be examined for corrosion of the impeller blades or broken impeller.

    The cooling system on these cars is not very good in terms of durability.
  • Thanks for the prompt response. Will give it a try.

    Yes, bleeding is a critical procedure on most every BMW cooling system. Make sure that the heater is on and set to maximum heat. There are two bleeder screws, one on the thermostat housing and one on the radiator. It won't hurt to raise the front of the car either.

    Get thee to a transmission specialist, I'm guessing it's a bad Torque Convertor.

    Thanks for the reply. Do you know how much that would cost me more or less?
  • I have a 2002 BMW 525i with 24,000 miles. I recently purchased 4 new tires. After the tires were installed I found my steering wheel shaking violently when I went over some holes in the road at very low speeds. It doesn't happen often. I brought my car back to the tire place and after inspection they told me that I had front lower control arm bushings that were cracked & leaking and that I also had leaking rear control arm bushings. My question is how common is this on a low mileage car? Also is it better to get the bushings removed & replaced or the whole arm replaced? Most important is this a safety issue?
  • I've been following the questions, but i havent seen one excatly like mine and im hoping you can help? Just like the others my car at idle will start to overheat? I have had to replace to upper radiotor hose because of a bad batch of hoses. Since gettign a good one that hasnt leaked, or the car? But i've also noticed that the temp comming out of the vents is mostly cool air? I have the water pump and thearsmistat and will put on this weekend. But my question is would a faulty pump and or thermistat cause the air to blow out cool when all gauges are set to 75 and air controls on 3 dots red?

    It sounds like the cooling system needs to be bled properly.

  • I don't think a control arm bushing can "leak". That sounds very odd.

    So you're saying that:

    a) the car did not shake whatsoever, at any time, prior to the new tires?

    b) that as soon as the new tires were put on, this violent shaking happened?

    If that's what you experienced, I think your tire shop doesn't know what they are doing.

    I'd take it somewhere else to check for a bent wheel, loose lug nuts, or some lift damage.

    BUT...if the shaking occurred before the new tires, then I'd have to say that these control arm bushings would have to be pretty wiped out to do's plausible but I'd sure get a second opinion on that.

    Safety? Sure, any violent wheel shake is an immediate safety concern.

    So you're job is to get some better information, with PROOF that you can see.
  • No, the car never shook before the tires were changed. It happens only rarely. I just became concerned because it is violent. It's only happened at very slow speeds. What is lift damage? I mainly wanted to find out if other 525 owners have had this experience on a car with low mileage.
  • Lift damage means that when they lifted the car to change the tires, they put the lift arm in the wrong place and damaged something in the steering or suspension. That's why I'd like someone else to look at it.

    I think they bent a wheel or something, or maybe there's a tire way way out of balance.

    It makes no sense that the car would not shake going in to a garage at 9 am and shake violently at 5 pm.

    Uh-uh. Something is not right here, given what you have presented to us.

    Those bushing can leak on an E39, as they are liquid filled. And they can also cause the problems described, though they may not be the culprit in this situation. More than a few owners on the Yahoo E39 group have encountered that exact failure.
