I just got the Hyundai EPC software downloaded. It was only 10£ so I thought why not... I have never used one before, but I must say that it seems that bying spare parts just came a lot easier for me. I did a quick search with my car VIN number in the program and all the data seemed to be correct with my car (manufacturing date, color, country where it was sold etc.). I also did a quick check with some parts I have bought from Hyundai dealer and the part numbers were exactly same. The EPC software gave me the same parts (part numbers) as the dealer had sold me. Now I should be able to find most of the needed parts from the good old interwebs with the actual part number.
It looks like I will get my money back with the first part order: Fuel filter from local dealer ~60€, from internet (KORAPS) ~30$. I guess I'll be ordering all normal OEM parts from there or ebay. It is so much cheaper.
I did not have speedometer/instrument cluster light dimmer. In my opinion the instrument light was too bright in night time. The winter is coming and it gets pretty dark in here, so I ordered rheostat/dimmer from koraps. It only took 10 days to get from Korea to Finland. And the best part was that it only took 5 minutes to assemble, thanks to the information (part number and instructions) found from this awesome forum:

EPC and the service manual are probably one of the best things I have bought for the car. They have and will save me a lot of money when servicing and getting the parts DIY way.
The EPC software is similar to the repair/shop manual. It's a large file (virtual computer with a actual Hyundai EPC software).
