Anyone know where here is information for beginners?
I want to start on my 406 2.2 hdi, but do not want to keep the car stopped ...

Try to get an idea what type of ecu You have there. Next You`ll try to find out what tool is needed to get this ecu done. Than You read original and start to learn Your readed software. Same time You will learn a lot very general and also specific stuff, which take a lot of time. How long, well it depends on You. Good luck
