No, Mercedes in Tonbridge had three on Ebay back in April, It is a tuning box which plugs into five places under the engine cover, also has the badges for the trunk, wings and cover.
It makes a big difference when in the S gearbox mode, its approved by Mercedes and saved about 1k purchasing and fitting myself so I am happy with the outcome, hopefully this is enough for me to be able to have the badges on with the approvement of forum members
