If your vehicle is approaching this mileage range, it’s wise to have your fuel injectors inspected. Regular maintenance, including fuel system cleaning, can also help prolong their life.
In summary, keeping an eye on your fuel injectors is vital for the performance and longevity of your BMW 535i. If you notice any of the signs mentioned, it’s best to address the issue promptly to avoid further complications down the road.
