OK this has been posted many times in various other threads but gets buried and there seem to be numerous threads popping up for VIN decodes. Decoding your VIN will display the factory Datacard showing options fitted to the car at time of manufacture. If the vehicle has had options retrofitted, these will not be displayed unless the work was done by someone who has access to update the Datacard. Firstly you need your VIN. This should be visible through the windscreen or on some vehicles it is inside the door. It should be 17 characters and should start WDB, WDC etc. If you cannot find the VIN, try putting your Vehicle Registration mark (VRM) in one of the following links. https://www.mercedes-benzwarranty.co.uk/Start https://www.bmw-warranty.co.uk/Login/Index These should generate the VIN from the Registration. You should now have the VIN which needs to be put into one of the following sites. Mercedes-Benz Car parts catalog | MBFans.info <<also has parts catalogue Checking VIN for Mercedes-Benz | CARInfo http://www.vindecoderz.com/ There is also an Android App available to download HERE You should now have you Datacard! If it does not decode, check your VIN from the car. If it still does not show, the vehicle could be too new. If for any reason it doesn't show, you can try posting a request in this thread and someone can try EPC or WIS. Happy Decoding!
