Success: I tried Clive’s procedure to reset oil service message and oil warning light. The message and light have now disappeared and have not returned thanks Clive.
However, my car is key operated and I had to make a slight change to the procedure on Item 2. I had to turn the ignition key to the “ON” position not the “ACCESSORY” position to make the procedure work. Suggest procedure for Key Ignition 1.6 TDci car is:-
1. With ignition key in off position, press brake and accelerator pedles and hold down.
2. Turn ignition key to “ON” position but do not start.
3. Message “Engine oil change due next service” and “Oil Service” light will display then then extinguish after 20 seconds.
4. Wait 5 seconds then turn off ignition. The warning lights will be cleared.
Thanks again for the advice it raises some questions the Message and Oil Light have 2 functions. They warn of fuel in the oil and the 12 month service has not been carried out.
My questions are:-
1. If the fuel is contaminated, do both the message and the oil light come on together or just the oil contamination light?
2. Should the main dealer reset the message and oil light when they carry out the annual service if carried out early?
3. Should the main dealer upgrade the Power Control Module (PCM) software to the latest issue when they carry out the annual service?
5. Why is the resetting procedure not in the hand book or given in the Haynes owner’s manual?
6. The oil contamination sensor is very cleaver bit of kit. How does it work? Where is it located?
