Hi,
I was on the phone with a fiat dealer and told, they don't reset memory only if they do the oil change. Also told that this light is only a information so should not cause any damage. I hope he was right and now wait for service before MOT to remove this message. Thanks all your replies and help
Well I'm just a Fiat owner*, but dispite what the dealer says, the 500 DPF supplement (see downloads) says
"Exhausted engine oil should be
replaced as soon as possible after
the warning light comes on, never more than
500 km after the warning light first comes
on. Failure to change the oil within the first
500 km may result in severe damage to the
engine and will result in forfeiture of the
warranty. Remember that when the warning
light flashes, it does not mean that the level
of engine oil is low, so if the light flashes you
must not top up"
So I think you should get it reset properly. The problem is that the ECU stops regenerating the DPF so it gets blocked.
