This service will provide a programmed steering lock emulator for various mercedes vehicles. This is a very common fault and will cause the vehicle to be unable to start , it is often intermittent but will eventually become permanent. The emulator will be plug and play upon being returned , all emulators are tested prior to shipping to ensure correct functionality , please ensure the correct diagnosis has been carried out on the car as I cannot be held responsible for incorrect diagnosis. I require the vehicles ignition switch and working keys to be sent to me to carry out this service. I can supply replacement keys at the same time if required but this will be at additional cost. Please get in touch if you have any questions
