i also have a 2.2 dti frontera 2001 model, and when pushed the engine management light ( which you refer to)illuminates. it will sometimes extinguish but normally will require me to switch off the engine and restart to clear the fault. when illuminated there is a loss of power. my vehicle went into the vauxhall dealer who had it for 2 days and could not find any fault with it....
