I have the full set of diagnostic modules (Multi Vehicle) for the P38..Petrol and Diesel (All models) which cover the BECM, EAS, Engine,SRS, ABS, Cruise control, HEVAC, Gearbox etc. etc.
The BECM modules allow me to unlock them and disable the Immobiliser etc.
Used to have Rovacomlite but the vehicle server went tits up a couple of months ago so I replaced it with the latest Faultmate Extreme.
see Blackbox Solutions Ltd - Designers and manufacturers of the best vehicle diagnostic tools. for more info.
when you say it went tits up, what happened to it? have you still got it and if so do you want it?
