I understand from one of the threads here the ECUs on the later cars are locked to stop changes to the maps to prevent tuning. Does anyone now if its possible to use an ODB tool like Autel to do normal engine diagnostics to find something that might cause a CEL for example. Modern cars are very hard to diagnose without such tools and access to the data.
