I dont know what those codes are.I would just like to mention that i can only give advise on what you tell me so it may help if you try to get the memory rechecked and the codes should look like this if immobiliser is the cause.
Key
Signal too lowt Fault in reading coil or wiring (contact resistance/loose contact)– Check (visually inspect) reading coil/wiring and connector and replace reading coil if necessary No or defective electronics in ignition key (transponder)– Replace ignition key, re-match all ignition keys and check function fault code→01176
The immobilser may have nothing to do with your fault if the warning light isnt flashing and it may be something else but the codes stored may eliminate alot.The ideal situation is to have the fault occur whilst the diagnostic equipment is connected and communciation between the immob and the engine control unit can be checked.Its a bit awkward but will try to help you out.Regards Jon
