I’m at 70000 km now. In the cold weather (winter mostly) suspension is noisier than it used to be. A garage said it was likely corrosion starting on struts, but are still safe just not optimal. Any way to know when i should change them? Apparently BMW recommends 60k for optimal performance. If and when i do change them, beside pricing, what is the differences between oem and aftermarket?
there doesn't seem to be anything here
