Yes, the DPF regeneration counter was reset so the "change engine oil" light is now off. Essentially, the software has told the ECU that the oil is good enough to protect the engine while it regenerates the DPF, as there is no actual sensor which determines oil quality. Obviously, I've done an oil and filter change, a really easy job, which just needs a Torx T45 bit for the sump plug and a 32mm socket for the oil filter housing. I bought the Selenia WR oil and filters from shop4parts who I found to be really helpful and good prices.
The software is easy to use but a licence must be bought, for 50 euros, before the facility to reset the "change engine oil" light is available. However, as the light came on after only 5,600 miles, it was worth buying as a Fiat dealership oil and filter change is £80 at my local dealer, whereas doing it myself and buying the cables and software cost £100, but I am no longer at the mercy of the dealership for so basic a DIY job as an oil and filter change. From now on, an oil and filter change (which I know will be done properly!) will cost me £40.
