P-2584 error Mazda 3 2010 1.6 diesel
 

Hi, I have a Mazda 3 2010 1.6 diesel and error code P-2584 is coming up on the OPD2 scanner. It relates to the fuel additive control module. My mechanic recently discovered that the original additive tank had a leak and replaced this with a second hand tank. He cannot recode the new tank when completing the diagnostics. Has anybody come across this issue before and what was the resolution. Thank you.
