Hi, please could anyone help. Recently had the engine management light appear and an air bag light on the dash, the car also started to appear mis-firing. Last week I pulled up, upon getting back into the car my key for electric locking wouldn't work and the alarm went off, I disconnected the battery to stop the alarm, then I changed the ECU/ BSI unit / Clocks and transponder, immobilizer module. The car still didn't start, it's coming up with 'Economy Mode' and today I have plugged in a diagnostic machine and it has come up with the following codes (attached) any ideas Please?
