So due to family issues I took a break from sorting this Volvo v70 2003 D5 SE Auto 2.4L

Decided today I would take it in for some fault codes to be removed due to the previous owner. Please can anyone confirm that

DTC is found not active - Means a stored code that is no longer active?
DTC is found active - Currently active? - makes sense but i could be so wrong lol.

I understand some of the codes

CCM-0021 Air Quality Sensor Internal Fault - Will have to buy replacement?

I was adviced that due to my age of car, these codes could be as simple as buying some MAF cleaner

ECM-1300 Mass air flow (MAF) sensor signal - Signal to High
ECM 130C Mass air flow (MAF) sensor - Negative drift

There is no issues though with tick over, acceleration etc. If faulty, they are not hard to replace, what do you think, worth a clean? Although I had this in my old Volvo V70 1997 2.5 TDI, cleaned it and problem solved, the issue was with the sliding arm and its connection to the board, this doesnt look anything like that one.

Next is

ECM-4405 EGR Valve - Flow too Low

I was told the unit needed cleaning due to soot etc, again have you had this issue and is cleaning the way to go?

The next one is a concern

PSM-E003 Configuration fault Faulty Configuration (DTC found active)

All the other faults surrounding this show (DTC is found not active) so I have no clue what this relates too except the possibility with my heated seats not working.

I have attached the sheet, I appoligse for my writing on it, I was looking to roughly price up based on the lesser of two evils.


Any advice with be greatfully received.
