Original or accessories ? My experience with an outdated steering gearbox at the beginning of December 2013 made my Mercedes W211 noises when steering, so to Mercedes it was determined that the steering was knocked out inside, an original steering cost 1800 euros. A familiar told me look at Ebay there sells the Fa car parts Jakob’s steering gearbox so I decided to buy one there 400 euros !heard good at.Lenkung ordered at Mercedes an appointment made old steering by the Übe Incorporation was made at Mercedes as it described the car parts of Jakob so servo pump , container cleaned and rinsed with oil , car at the end optically measured.Car picked up in the evening cracking was already happy away, unfortunately too early after about 100 km the container of the servo pump was empty again to Mercedes diagnosis steering was leaking so again appointment made and steering can happen again yes warranty is. g send,on the phone was told to me already in advance the 80% of the warranty cases to lead to a wrong installation to back.It passed 2 weeks when I asked for my steering it would be a test by car parts Jakobs go at least 6 weeks !!! Car stood at Mercedes dealer on the lifting platform asked me when finally the steering comb he needed the lifting platform what I can understand,after ample thinking I said to Mercedes they should have an Or iginal steering installation I also needed the vehicle urgently, after 2 days of vehicle finished and everything was OK.At the beginning of this week I called again at car parts Jakobs and it would have been in two days they had the test report of the warranty, after two days nothing on the third day then by mail of the test report warranty rejected the steering they were not flushed properly.The Aus und Einbaukosten in case of a warranty is not taken over by the warranty according to the GTC. Thinking your own opinion for me in the future there will only be original parts If that had happened to me at Mercedes and installation costs including optical measurement guarantee have been !!! I am now looking forward to other opinions.
