The BMW 5 series is an immaculate all-round design. With the combination of performance, stellar ride quality, and roomy cabin size, the BMW 5 series is brilliant in every way. The 5 Series gives you the performance you enjoy while not compromising on the high-end practicalities required for a family. Like all other performance cars, over time the BMW 5 series can present you with some common problems that may need to be addressed. Here’s a look at the most common 5 series problems, and how a routine BMW service schedule will prevent any niggles from occurring.
Air Conditioning Problems
Intermittent air conditioning issues is a common 5 series issue. The main problem is an alternating fan speed without any active control from the driver. In other words, the fan tends to change speed by itself, and only blows out cold air on lower settings. This may take you a while to notice if you haven’t put your fan speed right up for a while. It might be worth checking your air-con on all the fan speed settings. This is an easy issue to fix at a reputable BMW service facility.
Faulty Fuel Pump
Back in December 2016, BMW issued a recall on several models because of a fuel pump issue. This included the E60 5 series and the 535i model. The issues resulted in the fuel pump not working, which caused poor engine performance and engine stalls. This is a potentially dangerous problem when you’re driving at high speeds, as you can imagine. This issue was in part due to broken wired connections, which led to melting connectors. In case you weren’t aware of this recall and you’re experiencing engine stalls, acceleration issues, or misfiring, it’s recommended to head straight to your BMW service facility to get this sorted out promptly.
Cooling System Failure
Water pumps and thermostats tend to be common BMW 5 series problems. Keep an eye on your engine service light and engine temperature gauge, as these are where you’ll find warning signs that there may be issues. The cooling system on the 5 series is responsible for 25% of all mechanical faults on the 5 series. Allowing this issue to persist can lead to permanent engine damage, so it’s best to get it checked out fast.
Timing Chain Snaps
Timing chains are generally very reliable, but some BMW 5 series models have been known to encounter a timing chain snap. These snaps can completely disable your engine and render you motionless. BMW service inspections will ensure that your timing chain is maintained correctly and will replace it if need be.
Tensioners can wear out over time, which often leads to disconcerting squealing sounds that come from your engine bay. If you hear a noise like this, the first step is to do a quick visual inspection of your engine belts. Be on the lookout for cracks or other signs of wear and tear. Over time, damaged belts will also lead to problems with your cooling system, so it’s best to get your tensioners and belts checked out if you suspect a problem. The key to preventing worn-out tensioners is to invest in a factory scheduled maintenance plan for your BMW.
Sun Roof Seals
Some sunroofs on the 5 series are known to cause a whistling sound when driving. This points towards an issue with the rubber seal, which isn’t always installed correctly. It’s a common production fault and can be rectified easily. Even if you’re happy to live with the whistling noise, it can still impact your fuel economy by creating a drag effect. It’s best to get that rubber seal replaced.
