I have found little to no information on the subject of "oil dilution ratio reset".
a member once said the procedure was in the owners manual but when asked where in the owners manual the silence fell.
I have found this on subaru diesel crew https://subdiesel.wordpress.com/2011/01 ... pf-models/
the same information is on subaruforester.org http://www.subaruforester.org/vbulletin ... ost1034133for the Euro5 model
Diagnostic protocol (Extended OBD-II only since it is not implemented via SSM2 in ROM)
Manual procedure, see your car manual, you only have a few seconds to accomplish each step:
Transmission in neutral
Depress and hold brake pedal
Defogger ON
Lights ON (stage 1 = parking lights/DRL is enough)
Defogger OFF
Lights OFF
Defogger ON (again)
Lights ON (again)
Defogger OFF
Lights OFF
Release brake. Now the glow light (depicting yellow coil) will flash for a few seconds.
but with a little more information
My question how do I know if my wife's forester is the Euro4 or the Euro5 ?start engine (neutral I suppose)
depress & hold brake peddle
turn rear demister on
turn parker/clearance light on
turn rear demister off
turn lights off
turn rear demister on (again)
turn parkers on (again)
turn rear demister off
turn lights off
release brake
the glow plug light should blink for 5 seconds to confirm reset has been successful
note - the above steps need to be done pretty quickly. I think you have a max of 4 seconds between each of the above steps.. If it fails, let engine idle for 30 seconds, turn off for 15 seconds and retry..
as the Euro4 is via computer / scan tool only according to this thread https://subdiesel.wordpress.com/2015/06 ... ine-euro4/
Changing the oil and filter is a breeze... making the computer happy not so much.
