What causes a volvo S40 model 2006 engine code B4204S3 to ping like the older cars used to do after engine overhaul

SOURCE: Engine management light

my car volvo s40 2000 had problem with engine managment light. I took it to the garage & they did dignostic check and the problem was(reset the camshaft valve)he gave me the part nomber and i put new part in ad problem solved.i do not know the name of part but this part is next to the spark plugs on right hand side,its got 4 bullts and the wire pluged in to it. It might be not problem with your car becaus macanic told me that this is not the common foult with s40, with yor car it may be sensor. good luck

The best thing is to go to your local Volvo maintenance shop or Volvo experts to find out whats the problem..usually the coomon ones I think is the programs inside its ECU unit..you try this..ask the volvo experts to reset the ECU and lets see..if problem arise then it is no doubt you might need the sensor..hope this help..

Yes that is correct. The only filter is inside the fuel tank, and as I recall its a non exchangeable filter. It just gets replaced with the fuel pump when it goes bad
