Perhaps it wasn't an update as such, the dealer may have just reset a specific parameter or maybe in certain markets they specify a service after 3 months / 3,000 miles and that was programmed into the ECU. I never got a service bulletin number from the dealer. I no longer have the Mondeo, but it was me that made the original post :) Presumably Ford are hedging their bets, as it's cheaper to do a quick oil / filter change than risk having to replace DPFs under warranty later on. Oil drop, filter & update is free, under warranty. The ECU update is supposed to reset the parameters for the sensor.
The service manager says it's an oversensitive sensor relating to the DPF, which reports the oil has become contaminated and is putting the DPF at risk. The fix is an oil & filter change and an ECU update, they say. Rang the supplying Ford main dealer (very helpful on this matter) and they told me it's a known problem. No other warning lights, oil level is fine. In the last week or so I've had the "oil service" message come up on the information display when turning the key. My 2.0TDCi Zetec is nearly 5 months old and 3500 miles up. craig-pd130Ī number of owners of the 2.0TDCi have reported the "oil service" message coming up on the in-dash display, often after just 3000 miles or so (service interval is 12,500 miles or one year).
