(T) Oil Light Flashing

This is sort of my point, a bit. How can a modern oil degrade in two months? Or two thousand miles?

Or have I misread something here or maybe I'm not grasping the nettle? Am I being a clot cos if I am please tell me (nicely!) I can handle it! Lol.

oil degredation can drastically increase on a poor running vehicle or one that is only used for short journeys therefore not letting the DPF regenerate.

Right. I see. ok. Ta.

So if I am understanding this oil degradation index correctly, the condition of the oil is not physically or chemically measured. It is a number crunching of electronic and mechanical signals that have reached calculated values within the ecu to suggest that the oil has degraded to whatever extent. An assumed or suggested degradation of the oil, if you like?

And therefore, no matter how often you change the oil, if you do not reset the index it will eventually assume that the oil is degraded and turn on the flashing oil light?

So at every service and/or oil change, you must reset the oil degradation index?

Sorry about the questions, just trying to get it straight in my mind? Thanks for your patience!

I think in my case because the light was not on when it was changed they forgot to reset it

Yes, indeed, again slightly what I was trying to get at again. It doesn't recognize when the oil has been changed and thus can't obviously physically or chemically measure the state of the oil. It's a manual reset. That's what cheeses me off a bit! Lol.

It only takes in to account miles covered and distance of journeys etc.I think

also start ups,engine temperature, regenerations, dpf temperature etc...takes loads of factors into account which is why the system is currently the best around. I'll be honest and say that I have had one DPF fault not down to the customer (knowingly or not) and that was a temperature sensor on the DPF itself going out of limits.

We had our dpf light on at only 2000 miles.They said they purged the system.Whatever that means but it sorted the little warning light out

They would be refering to a 'forced regeneration'.

That was it lol

Sounds like the sort of girls I end up going out with!
