Fuel filter replacement and review 💭
It's critical to check the manufacture date of the parts you purchase, even genuine BMW parts.
We replaced the fuel filter last year in August, and we have traveled over 35,000 miles over the year.
We have noticed a strong smell of diesel and suspect the fuel filter is leaking again. We were right.
Why?
It was old stock; the rubber had probably deteriorated. But anyway, we have traveled close to 40,000 miles, which is the standard interval for changing it.
This time, we managed to purchase a filter made in 2026. Fingers crossed, we'll check again next year and confirm.
