body controll unit

Hello my friends, first of all sorry for my English, it is not the best. Could anybody tell me where is located the body controll unit on the Discovery 2. I’m almost sure that I have a problem with it and I rather replace it entirely than try to fix it because the first authorized service is too far from my home. I'm an engineer and a self didactic guy and I fix my car with my own hands but that problem is above my knowledge. It’s better for me to purchase the unit and just replace it but I could’nt find it so please help me with some information. All the best from Transylvania.

Above passenger footwell, but its not going to help you much as it will need to go on Testbook to be programmed to your car.

Many thanks, until now I managed with all the problems (mostly mechanical) but it seems that one is above my skills. I will check a specialist equiped with testbook. All the best from Transylvania.
