Put ignition on, but don't start it. Put on reverse and go put your ears against the sensors. You should hear sparkling noise. If not, then sensors are broken or they don't have power. My parking block was at trunk. Left where there is a cloth. You need to remove one plastic nut and then you can see the block. If you have skoda original parking sensors, then diagnostics should see, what's wrong.

Hi i tried it out all came back with the sparkling sound.so does that mean its the control box fault?unfortuantely i dont have a VAGCOM cable so i wont be able to do the diagnostic myself.How much for the new replacement?and where exactly is the control box?

Is it OEM or aftermarket? If it's OEM then vagcom can diagnose the fault. If not then, you should search from trunk under the left carpet that's covering wheel. At least my control unit was there.
