Damned Parking sensors
 

Are on the blink again. No errors on VCDS but not a beep to be heard,

any suggestions chaps?

what is the live vcds data showing? can you see the distances? it could be a blown speaker?

A failed speaker will show in VCDS. Check the Fuses. Then as suggested hook up VCDS for the live outputs.

thanks , chaps, it beeps if I press the parking sensor button the dash so doubt its the speaker. I didn't realise i could get real time info on them with VCDS, will give that a try
