I bought this leon cupra as ive always fancied a yellow one despite its a little patchy in areas and that its had a stage to remap with no proof but its nippy, the eml keeps coming on every once in a while and the codes that come up are: 17705, 16804, 16795, its suppose to of had sai,N249,N112 delete and also decat, sometimes the sai comes on when I start the car and sometimes it don't can anyone shed any light onto this for me please? I reset the codes but they come back. thanks in advance
