Im doing aerodynamic testing on a car and my doctor asked me to do CFD validation for my results? What did he mean? or what Im supposed to do?

you are making things complicated. could you please just briefly tell me what is it about?

In a nutshell verification is checking you are solving the right equations, and validation is checking you have solved them accurately enough for your purposes. (Reference: http://www.grc.nasa.gov/WWW/wind/val.../tutorial.html)
