Engine Light 2009 35i

[RAYK47]

Hi all
Just wondered if anyone could help with the results of my scan, i used a paid app call Car Scanner. My main concern is the first one initially but i dont know why it says inactive) after it. I have left the modules where nothing was found in the log in case it helps with any other questions.

I am a complete novice with this stuff.

Well looks like either the DSC has died or something else on the data bus is dragging it down..

Needs a full ISTA class network scan to see which networks / modules are on line and which are not..

Thanks B21, seems i need to get it scanned at a garage then.

Yes sadly this area is one of those 'complex' ones...and..sometimes only a substitution will prove the fault..
