Actually I took the old one in to my local hydraulic shop and the guy got a terrified look when I said Mercedes, after he looked at the hose we just took it apart and I put it back together while he dealt with another customer (I got impatient) He said it should be as good as new and the hose we used was actually better than the OEM hose so I feel good about that. I'll get a chance to give it a good test soon as I'll be loading up the trunk with quite a bit of weight for a trip next week.
