[Rusco25]

Hi all new to this page I have a mercedes vito 109cdi 2004 and the engine management light keeps coming on as soon as I get near 80mph put universal diagnostic computer on and no faults if turn engine on and off it goes any ideas thanks again russ

If it's not showing up with universal reader, then may need to have it read with STAR (or different reader) at an independent (or dealer but more expensive). Not uncommon for faults to clear themselves but will still be logged.

Have the codes read by a Mercedes dealer. if the light is coming on, there must be codes.
