Common BMW Faults
BMW’s are one of the most popular vehicle brands in the UK. Whether it’s the sophisticated 5 Series or the sleek looking 3 series, there’s an option for everyone.
While BMWs boast exceptional craftsmanship, it’s not uncommon for owners to occasionally run into some hiccups with their beloved vehicles.
In this detailed guide, you’ll discover the common issues BMW owners may come across, how to spot these problems, understanding their root causes, and how to keep them at bay.

The Most Common BMW Faults You Need to Know About
By understanding the potential problems your BMW might face, you can address them in a timely manner, ensuring costly future repair bills are kept at bay. You’ll even enhance safety, performance, and resale value.
Here are some common BMW issues we see at Fergies:
Camshaft Cover Gasket Issues – If a mysterious brown stain resides under your BMW, it might hint at an oil leakage, a fairly common BMW fault. BMW camshaft cover gaskets are the seal between the valve and cylinder head. These can be the main cause of leaks.
Timing Chain Problems – BMWs sometimes have timing chain problems. Regular operations can create slack in these chains. Failing to keep on top of your vehicle maintenance can lead to quicker deterioration, causing jarring noises, irregular idling, or even dashboard warning messages.
Water Pump Faults – BMW owners aren’t strangers to water pump malfunctions. BMW models like the 2012 BMW 650i, 550i, and Mini Cooper S have even seen recalls due to this concern. So what’s the main problem? Overheating… which is attributed to a few design flaws. BMW’s unique plastic and electric pumps distinguish them from conventional ones. A failed pump can push the engine to dangerous heat levels, which can result in further (and costly) damage.
Cooling System Issues – An engine’s cooling system is its guardian, ensuring the engine temperature remains in check. But BMWs can sometimes suffer problems here. Regular servicing and maintenance can usually keep these issues at bay.
Fuel Pump Faults – Some BMW owners will see issues with their high-pressure pumps, with symptoms manifesting as shaking or poor acceleration.
Thermostat Troubles – The thermostat closes to help the engine reach the optimal temperature and opens to maintain it. In certain BMWs, the thermostat can remain closed causing overheating. When it does, your vehicle is at risk of cracks in the radiator and potentially costly engine damage.
Door Lock Problems – BMW’s door mechanisms mostly operate seamlessly. Yet, sometimes, they may deny entry or exit, especially in models like the BMW X5. The remedy often lies in updating the door’s lock software. Got a door lock issue? Call Fergies for a quality fix.
Electrical Issues – Electronic faults might occasionally plague your BMW—modern vehicles are full of computerised components, each can suffer a list of malfunctions. However, with the proper care, these can be seamlessly managed. Luckily our BMW specialists at Fergies can help.
Facing any of these issues? Fergies is just a call away. Our specialist BMW technicians can solve any issue your vehicle may have.

How to Prevent Common BMW Faults
Regular servicing and maintenance of your BMW not only lowers the risk of faults, but also keeps repair bills down. And most importantly, it keeps you safer on the road.
As soon as you notice an issue with your BMW, it’s crucial to address it immediately. Whether your BMW feels different, exhibits a shift in performance, or something seems amiss, remember our experts at Fergies can help.
To prevent frequent BMW problems, follow these steps:
- Exercise caution over speed bumps, sidestep potholes, and don’t drive erratically.
- Regularly review your BMW’s interior and exterior for signs of wear.
- Keep an ear out for weird sounds – grinding, clattering, or screeching, as these often signal your BMW has a fault.
By driving safely and ensuring timely maintenance of your BMW, you can keep minor issues from developing. This proactive approach not only keeps you driving smoothly but also optimises your vehicle’s resale value.
Does My BMW Warranty Cover These Common Faults?
Should your BMW encounter an issue, the warranty may have your back. If you bought your BMW through an Authorised BMW Retailer or a BMW Service Authorised Garage, you might be within the scope of warranty coverage.
Inspect your vehicle’s warranty handbook for a detailed understanding of the terms and conditions. If you’ve invested in a pre-owned BMW, thoroughly examining your warranty documentation will reveal whether potential issues are still covered.
