hi guys can any one help i have an audi q7 2007 model.  My parking sensors have suddenly stopped working and dont know why.  Light flashes is orange on sensor button but no display or continually beep when parking, close to object.  

Wondering if this can be resolved easliy or just needs a reset.

Thanks

Do you get a constant tone for a few seconds and then nothing after putting it in reverse? If so, this could indicate that one of the sensors is faulty...

I JAMES THAKS FOR GETTING IN TOUCH YES IT DOES BUT NOTHING ON THE MMI HOW DO I CECH SENSORS   THANKS ROBIN 121

You can scan with VAGCOM and it will tell you which sensor is faulty

 

or I believe I have read somewhere:

 

With the ignition on (no engine), engage reverse and jump out after the constant beep. Put your ear close to each sensor and you should hear a clicking. The one that doesn't click is faulty. 

 

Once you replace the faulty sensor that should cure the fault.

HI JAMES I HAVE FOUND FAUITY SENSOR I WILL CHANGE IT AND LET YOU KNOW THANKS AGAIN ROBIN 121

That's good news Robin, yes please keep us updated!  :)
