Tried a suggested ECU reset following this warning - battery disconnected for 30mins and then reconnect, start and let her sit at idle for 10 mins.... you guessed the mcsf warning is still there.
Car still drives fine with it but worringly can cut all electrics randomly for a few seconds and then all returns to normal > not the best thing to happen on these dark nights. Also refused to start a couple of times with the mcsf symbol the only dash light to show up.... had like a pump noise switching on and off randomly even when ignition not even turned ? any ideas folks > does this suggest a dodgy fuel pump?
mechanic to check the air pipes / turbo pipes tomorrow and give the maf a clean to see if that helps.
