2007 Volkswagen Jetta Hi Vw 1 9 Tdi Other Day Esp Light Came On Control Over

Hi, i have a 2007 vw jetta 1.9 tdi and the other day my esp light came on and i have no control over it using the esp button, my traction control and abs dont seem to be working either! The car is due to go to a local garage for a diagnostics reading so i will hopefully get an idea of what it is back, but does anyone else have knowledge of what this could be and roughly what it may cost to put straight??

Thanks, sam!
