Thought i would give a update on progress, not sorted the issue yet mainly due to not enough time to look at in depth ,but i have purchased the Gap IIdtool bt and done a fault search then contacted gap tech team ,they got me to email the fault codes direct to them from the device which is cool and patrick from gap replied very quickly with what he thought the problem was and with a electrical diagram to help fault find .
Its good when you get a company that gives this kind of service so hopefully will get to the bottom of the issue ,see below the reply from gap
P0607-00 Control Module Performance - No sub type information
Corrupt engine control module software
Engine control module power supply fault
Engine control module failure
Using the manufacturer approved diagnostic system, re-configure the engine control module with the latest level software
Refer to the electrical circuit diagrams and check the engine control module power supply for open circuit. Repair wiring harness as required.
Since this car has been in an accident, a wire or fuse issue is more plausible. Wiring attached.
Same goes for the Ambient air temperature sensor fault.
