When to replace timing belt on BMW X5 4.4i?
According to BMW, the timing belt on the X5 4.4i should be replaced every 100,000 miles or 10 years, whichever comes first. However, some mechanics recommend replacing the timing belt sooner, around 80,000 miles or 8 years. This is because the timing belt is a critical component of the engine, and if it fails, it can cause serious engine damage. If you are unsure when your timing belt was last replaced, it is best to have it inspected by a qualified mechanic.
