Free disabled bus pass on esa/dla

Hi,I have spastic depligia,have difficulty walking and I currently receive ESA and DLA mobility component.I have just been granted a free disabled bus pass.What I would like to know is will (if I use this) affect my entitlement to my above benefits and are the DWP notified when someone is granted a disabled bus pass.I am asking as when you are called in for a WCA I hear that it is better to attend by taxi than public transport.Thank you.
