2007 S80 D5 - Engine Management Service Message
My S80 D5 has done 53k miles and no problems. The the DFP / oil level software update and engine label was done in 2011 on a recall. The car has been regularly serviced.
Then last week the dreaded yellow exclamation mark came on with the "Engine Management Service Required" message. It was permanent whenever the car was started or running. Took the car to my local (and excellent) independent Volvo specialist. They ran an OBDII sweep and scratched their heads a bit at an error code which indicated something wrong with the oil level, or with the oil level sensor. It was clear that the oil level was correct, at 1/3rd below the max mark. So all they did was disconnect and reconnect the sensor, re-establish comms between the sensor and the car compuetr system and hey presto - problem solved! Been running a week now with no more messages.
The lesson is if a garage wants to fit and charge you for a new oil sensor, just ask them to disconnect and reconnect the existing one first.
