eml light on

[s3 man]

Hi guys just wondering if any1 can help. i've got an s3 that has been mapped with a 3" down pipe and de cat, but the person who has done the map turned the light off and has now come back on after a few days....any ideas what it could be as i have this fault code:

17526- Oxygen (lambda) sensor heating: B1 S2: open circuit
P1118- 35-10---intermittent

thanks
