Just bought this '97 850 with 130K (non-turbo). When I start the engine I get some vibration inside the passenger compartment that feels like the engine is banging against the frame of the vehicle. Once the car starts I rarely hear it. I'm wondering if I have a bad motor mount (I see there are a few of them in the diagram on eEuroparts.com). Are there some that typically go bad?

 

Yes they are know to go bad. It's pretty common. We see it here all the time.

 

mine is actually bad right now as well, when i accelerate at higher speeds my 850 vibrates pretty bad, but motor mounts are not that expensive to replace.

 

I would start with the top mount in the engine bay and go from there. That one is probably the easiest to replace
