Don't miss 2nd EGT sensor as plug is pretty hard to reach the plug on side of the engine under cylinder head it os on your right when you stand in front of the car there will be 2 plugs 1 for engine speed sensor and 1 for 2nd EGT sensor if you disconnect wrong one engine won't start. You need to leave 1st EGT sensor connected and disconnect 2nd 3rd EGT sensors and Differential pressure sensor then coil light will go off together with Software Incompatibility Error.
