Oil change on Diesel engine and ECU service reset
I was considering doing my own oil changes between major services at the dealer to keep the engine oil in good condition as I have done previously on petrol engines.
However I have read some details that the ECU needs to have a counter reset whenever the oil is changed so that the programming for the DPF regens can run correctly.
Apparantly not doing this can cause problems in the DPF.
Does this mean nobody besides a Subaru dealer can effectively change the oil?
So I have a number of options.
1. Don't do the changes - leave it for the dealer. Not a real problem for now, but as the vehicle gets older I would like to do my own servicing.
2. Don't worry - do the oil change and dont reset the counter. If every second change is done at the dealer and they reset the counter does this really matter ?
3. Get an OBD II tool and reset the counter ? I'm not sure how to do this, some googling has not found any method for this vehicle - you can get tools for many European models. The Scangauge II seems to be able to send commands to the ECU but I'd have to know what commands to send... maybe in a couple of years the aftermarket tool providers will have developed a tool for this...
What do people think ? Has anyone changed the oil themselves on a this diesel engine, or used a non-subaru service centre ?
