Hello,

My wife has a 2018 M550i we purchased new in 2018. The car has 77K miles and has been problem free. I recently noticed an oil leak on the garage floor when she was out. She took the car to the dealership and leak is reportedly coming from the front driver's side strut.

Does anyone know the mileage at which the struts or shocks need to be replaced? The dealership is going to replace the strut, but I am wondering how long before the others need replacement.

Thanks in advance.

It really depends on your driving style and the roads you drive on. On my E90, I had the rear shocks replaced at 60k miles.

Firstly, lemme say you should replace both fronts, not just one.

To your question, it depends. I have a 2012 e92 with <20k miles on it that rode like crap. So I went with new struts/shocks front and rear. Went with OEM-type Bilsteins, and now it rides very well.

My e46 got to 200k miles before the rear shocks seized.

The e60 got to 90k miles before the rear end got rough.

My dad's e90 has 75k miles on it with some nasty rear shocks. They're getting replaced before daughter inherits this car next month.

Thanks for the response. I am considering changing both. The dealership is doing the work. The price for one is $1,600.

Ugh, you must have the adaptive suspension?

Is that more expensive? I do have driving assistance plus package. The car is pretty loaded, but it does not have the rear wheel steering.

Apologies, I know very little about adaptive suspension. I passed up that option on our G30 last year. Yes, it was more expensive, but I was happy with the standard suspension so stuck with it.

ppointer thanks for the response. My wife picked the car up after returning from business trip. The dealership gave her a 2023 M850i as a loaner. Anyways she says she does not feel a difference between before and after the strut replacement. We are nearing the end of our extended Platinum BMW warranty which I don’t think we have used. The car has been pretty much problem free so I feel like the extended warranty was a waste, but am happy the car has been reliable. Maybe I will get the Route 66 warranty discussed here. I heard they cover replacement of shocks and struts which is weird as these are normal wear items on any car.
