I tried my bluetooth adapter and Torque on my S55L... read a few things but not very descriptive. Bought the iCarsoft here :
Mercedes Benz iCarsoft i980 Multi System Diagnostic Tool - SRS, ABS, Engine etc... Works very well indeed, £90 inc VAT and delivery (they even take Paypal, and as I had some funds in my Paypal account at the time, it felt like it was free!!). Reads everything as far as I can tell. seems to allow resets of everything too, very fine detail (tyre pressures, temperatures, etc) and very descriptive fault code explanations. +1 for this unit!
