It's a LOT more complicated then just wiring a serial connector to one end. This link offers a kit where you can make your own adapter, or you can buy one premade.

o, is it possible to reprogramm ECU without pulling it out on this car model?

"All" ECUs are reprogrammable without being uninstalled. You will need a reflasher hardware / software and availability to the flash binary files. Well beyond hobbyist budget but every day in every dealership. The methods to flash a vehicle are becoming more standard, but until now, all vehicles are flashed in an OEM proprietary method. The normalized method is called "Pass thru reprogramming".
