I had a local garage, not mb specialist but with a good reputation, replace the NSS two years ago after I couldnt start my car on cold days in either P or N. Many months after replacement, just for fun I tried to start the car in N, but it wouldn't start; it only starts in P. Would that suggest the NSS was bad or not properly aligned? Thanks.
