is there any risk to use a non compatible DIM?

Carlitos 1988 - read this about fuses and if it doesn't make sense do more reading:

The only way to know is to actually plug in the DIM - I would expect a fuse would blow before further damage happens, but I don't know for sure. It depends on what damage you did to the DIM. You know that your failed DIM didn't cause problems other than lack of functionality. If your repair shorted all sorts of circuits on the DIM then the Volvo Truck shop may be correct.

I personally would take the DIM to a TV repair shop and ask them if they can fix it or at least clean up any shorts that you may have created. Labor of this type is cheap in Peru and the skill level is just as good as the rest of the world.

Darrylrobert - the numbers relevant are 8637993 and 8602471. Search for these and look for cross references to newer DIMs. If you go to a Volvo dealer website you can search off these part numbers and figure out what will work.

The S/No I think is the software loaded into your DIM when it left the factory (2248). You can confirm this by looking up software part number for the DIM. The software many times is updated to a newer version - this can also be found by using a Volvo dealer website.

well the truck shop told me the solder cream which I used in order to solder the posible failures damaged the green board, because the cream was all around and made a mess.

also the first time I plug in after I did the solder cream thing, the Dim started to BURN from inside, sounding like pop corn.

I opened it and there was smoke smell

but it was until night that I realized smoke was coming from the Epson square chip (I left the Dim open)

so It was burning and it burnt on of the "legs" of the chip.

it occurred everytime I plugged in the dim so whenever I plug in, it made electric contact and started to burn.

after some days there was no more smoke. just smell. and after a week Epson chip was totally cold.

in that condition I sent it to the truck shop.

As I suggested you could have created shorts with your solder job and burned out the DIM. From your latest description that is exactly what you did. It appears that the original DIM is beyond repair.

What is the part number as you will need a correct replacement? Someone on this forum should be able to steer you to the correct model years that would work with this number. Best to post a picture, like the other forum member did, of the label; and include the year and model of your car.

It is best not to use the DIM in its current state.

You really should have asked and posted before, not after. It may have been possible to fix your poor workmanship before you plugged it in or at the first signs of trouble.

Live and learn.
