I do understand what you are saying and I agree. The customer only came to our shop once about the vibration and a stalling issue that another shop could not find. We found the stalling issue and repaired it, and thrust arms that were worn but the customer declined the repair at the time.
I just didn't want us to be confused with the other shop that just changed parts with no success , thats not what we do, we actually did not install any parts his stalling problem was repaired during the diagnostic process at no extra charge .
Also the vanos bolts that we changed on the other customers car you are speaking of are a high failure point on the s54, we change them at the same time as inspecting vanos hub that also fails often, and performed a valve adjustment. It's actually more of a preventive maintainance on the s54.
I hope this clears this up for you.
