Common Problems of the BMW 530xi
The BMW 530xi is a mid-size/executive car that had its roots in the BMW 5 Series, a line of cars started by the manufacturer in 1972. The 530xi is part of the fifth generation of the series-an award-winning lineup that is considered as the heart of the BMW brand. The
x in 530xi comes from internal BMW-speak. It means xDrive, a BMW technology that combines an all-wheel drive with a variable torque distribution. This system redistributes power to the wheels with the maximum traction as needed during a specific driving situation, potentially reducing loss of control. With all the advanced features of the 530xi, however, it still has some common problems that the manufacturer needs to address.
Front passenger airbags
Small cracks in the sensor mat of the 530xi can lead to a malfunction of another component-the activation of the front passenger airbags may be affected. Frequent entry and exit can cause cracks to eventually develop in the mat, causing the front passenger airbags to be deactivated and the air bag warning lamp to be illuminated. The passenger airbag
on-off switch will also be lit. BMW recalled several 530xi's with this flaw starting in 2006.
Brake pad wear sensor
The brake pad wear sensor of an older 530xi causes the brakes to squeal. BMW replaced the brake pad wear sensors in 2006 and colored them green to mark the difference between the new redesigned sensors and the old ones. The noise from the brake pad sensor can be removed by going to a large open parking lot, going fast in reverse, and hitting the brakes hard. This removes the brake dust from a rarely used portion of the rotors, which causes the squeak.
Battery cable connection
The positive battery cable connection in the trunk of the 530xi has been observed to overheat. The bolt securing the insulated battery cable connector at the trunk floor panel loosens very easily, causing electrical resistance to shoot up and overheat to happen. A number of mid-size cars were recalled by BMW in 2012. Dealers secured the battery bold cable connection without charge.
I recently had a service engine light go on in my BMW 530xi. A message also popped up saying "low oil pressure," but it did not appear again. Should I check on that low oil pressure warning?
Even if that message won't pop up again, it is best to follow up on the warning. Your BMW 530xi tends to burn a bit of oil, which is a normal occurrence. However, if you neglect refilling the oil tank, your car's engine will not be able to maintain oil pressure and get damaged. Before you drive your car, check the oil level using the dipstick and see if the level reaches the mark. If it's lower than the mark, either top off the oil tank or drain the oil and refill a fresh batch.
Water seems to be leaking into the battery compartment of my BMW 530xi. Is this a manufacturing defect? How do I fix it?
The sunroof drain is most likely clogged at the entry of the drain hose or the drain cock. Fortunately, you can repair it by yourself in less than 30 minutes. Open your BMW 530xi's sunroof and look for the drain holes. Use a vacuum and small-diameter vinyl tubing to suck out the clog. If that doesn't work, try running a very small flexible plumbing snake down the tube to break out the clog. If this still doesn't help, you may need to seek help from an auto repair shop.
The message "transmission malfunction" shows on the computer of my BMW 530xi. What does it mean?
When this message appears, it means that your BMW 530xi's transmission is not working as BMW designed it to work. Transmission problems only go two ways—either it doesn't work at all or it doesn't work smoothly. Check your transmission fluid. If the level is low, your car will shift poorly, which will eventually lead to transmission damage. You must inspect the fluid level at least twice a year. If you notice that you are losing transmission fluid regularly, then you may have a leak. Another component to inspect is the filter, which is vital to the transmission's performance. It collects dirt and grime to keep them from flowing through the transmission. Over time, the filter loses its effectiveness the more dirt it collects. You must replace it regularly in order to prevent damage on your transmission.
My BMW 530xi is running rough and the service engine light came on. What's causing this?
This sounds like an engine misfire and you will have to scan for codes. Misfire is a common problem that badly affects your car's performance. When you scan for codes, getting codes within the range of P0300 to P0312 has something to do with misfire. This problem is usually caused by loss of spark, air/fuel mixture that's too far out of balance to ignite, or loss of compression. These are usually due to worn, fouled, or damaged spark plugs, faulty spark plug wires, or a cracked distributor cap.
