Sprinter T1N1:Check Engine Light

Got low on diesel fuel--down to about 2 gallons. Started Sprinter few days ago, got STEADY yellow engine ikon ie check engine(ECU). Boogied down to service station and filled up. Still light on. Stopped and started it 4 times and after a short drive into town and back and restart, light extinguished. My conclusion was scan fault 190 (from list I read on net) which is basically a fault recorded from the rail diesel pressure sensor. AM I correct in that as the manual says, if the fuel in tank is low you can get this and to do what I did or otherwise see your dealer. Comments? Normally I keep tank at least half full. I do know that if the yellow ikon is FLASHING, then that could mean engine problems and not to drive it far, if at all.

    I've read the same in the manual - that low fuel level can cause the light to come on (haven't had that experience.) But could be something else.

    In June we woke up to a dead coach battery, luckily last day of a road trip. Got a charge from Good Sam road service within an hour and drove straight home directly to our local service guy's parking lot (not a Mercedes or Dodge dealer.) The same check engine icon light was on the whole time (not flashing).

    The next day he located a new battery, installed it and the warning light went off, never to return.

    Easy fix, happily. I think our old battery was at least five years old, installed by previous owner.
