Perfect DIY code reader at the just under £100 price point. Great to carry in the spare wheel well for diagnostics if a warning light comes up while on a trip. Has more Mercedes specific systems coverage than the cheaper ones. But be realistic it will not give the sort of detail a pro device would at many hundreds more.
Seems t be a quality product. Easy to use and can be set for my specific model. Looks like I can use it to read codes off other vehicles but haven't tried that yet.
Didn't work with my MB Sprinter 313 CDI 2001. Connects ok, but gives linking error when trying to read fault codes. Works ok with other MB(ML, S...) models.
