After replacing the brake lights and the battery, it worked flawlessly for a day or 2, then when i stopped the car gave me 3 errors , check engine, remove water from separator and engine overheating. After turning it on again, its starts normally but stays in limp mode(no more than 2k rpm). Error codes on OBD2 are P1590 and U0100. Checked all the fuses and they are working fine, but the car wont turnoff the console even with the key out. help please
