I don't think that is BTBR's point of his post.
He's pointing out the poor attitude that V*n*s had to their servicing responsibilities.
From the reply it would seem they want to shift the blame and avoid taking any responsibility for overlooking an item that is crutial for riders safety.
The bike had only been serviced by the same place since it's purchase.
The person who owned it before was not mechanically minded and left all servicing to that dealer.
Now the previous owner in a perfect world maybe should have notice the bolt missing.... but a BMW dealer whom you leave your bike in with for servicing definitely should.
BMW servicing is not cheap and is meant to be to a very high standard.... when you get all your servicing done with them you expect nothing less that a bike that comes out safe to ride on the road.
I don't know much about brake pad wear... but if the same pads were on the bike for 5000 miles and haven't shown massive wear it's hard to believe that 600 would have taken the pads down so far,
At the end of the day when you leave your bike in with a BMW dealer and get charged heafty sums for them to service and mantain your bike you should expect nothing less than a top class service.
For them to despute the brake issues shows a lack of good will and customer care to say the least.... what would it have taken to say we'll fix it to show our good will... price of a set of pads and a bolt
