I am owning 2.4i Volvo s40, I am having a problem of a dash board message ENGINE SYSTEM SERVICE REQUIRED. This message keeps coming up while driving. I have tried to reset but just keeps coming. please help
you would probably need the codes read to find out why its coming up, then once you know the cause then you can fix the reason it is coming up, on my V50 2.0d I had that message, and the codes it gave were a pending low turbo boost, in the end I tracked it down to a broken wire on the manifold air pressure switch, fixed the problem and the code went away.
Also how are you resetting the codes, that sort of implies you have a code reader to reset them. if so, what codes are coming up?
yes i think your correct i had the reminder and moments ago cleard the massage priore to reading your post i did a little tube search for clarification and found a usefull video i would say onc you have followed this short tutorial and when holding the odometre the caution light will flash realese it befor flashing stops i let it flash 3 times or more and upon realese a reasuring bong sound to confirm reset.
