Sorry i didn't read the post correctly. Never realised you were using GM Infotec.

Isn't that a pay per use system where you can either pay per hour or yearly if needed.

I was looking on theere website the other day with a mechanic from a dealer, doesn't look to expensive for the SPS files from what we could make out.

Something like €20 per hour for the SPS files and €400 for the MDI software per year which i think is aceptable.
