JustAnOldCoot Posted November 1, 2022 Report Share Posted November 1, 2022 Hi Folks, Brand new here. I'll give you some background on the car and then will ask my question at the **** section if you want to skip the details I bought my S40 at auction for $540...have done all the repairs myself except alignment...to include: Timing Belt, Water Pump, Oil Pump, Fans, Fuel Injection Pressure Sensor, Fuel Injectors, Coils, Plugs, Cam Sensor, Thermostat, Temp meter, PCV box and venting hardware, etc. etc. etc.... ****I have been troubled by a dashboard that has all the background illumination bulbs (LED) flashing off and on, randomly flashing at high intervals, part of dash illuminated and not, just a whole lot of PITA...as well, random codes getting thrown (14, 15, 25, 44, A1, P0101, P0106, P0118, P0128, P0172, P0303) that are not parts-failure related as some of the components coded have been changed multiple times within days of each other (in case of bad new part)...so in talking with a guy who had same issues in a Dodge (Dash, strange codes), it was his ECM. I have since procured a "guaranteed used" ECM and am going to replace it this weekend. Long story short...is there a need for me to take the ECM in and have it programmed by Volvo (to the tune of a couple of hundred $ I'm sure - heck a key programming cost me $225)? Can I just install the new ECM and go for it? Do I need to go through a driving sequence to get it to recognize the new values from the engine? Many thanks and God Bless you and yours!
