"remote interrogation is no different to what you read on the tool you plug in"
Sorry to disagree Steve, but the remote server plug in will be encrypted and special codes will be required to access the modules and ECUs. Probably very similar to the Volkswagon system, I believe it is called "GEKO"? I know that the Aftermarket and independent workshops in the US are fighting this, as it has restricted their trade. Perhaps you know more about it? regards, Gwyn
