I have just bought a 1998 W220 S Class 430 petrol which has a 16 pin data link connector under the dashboard. I already have a Gendan engine check diagnostic package which works on my car and gives me live data, graphs etc. even 'though it is for 2001 onwards petrol cars. When it communicates with the car it uses ELM327. The icarsoft MB V2.0 looks interesting, and it has a lot of functions not covered by the Gendan engine check. Has anyone bought an icarsoft MB V2.0 for a pre-2001 petrol car and, if so, do all the functions work?
