Parking sensor gone faulty after I bought this car about month time. all of the sensor didn't work. Is there any fuse or the control need to replace? Thank you everyone.

There will be a fuse, but it could be a broken wire or a connector has come loose. If you only bought the car a month ago and it was from a dealer then take it back and get them to fix it as it is their legal responsibility

It can be a lot of things.
Code read with VCDS will tell.

Thank you for reply.
I bought the car from the vw auction so there wasn't any warranty.
I had VCDS checked it came six faulty code for every sensor. It saids Open Circuit - Intermittent on every single sensor.
Anyone know about these please?

Highly unlikely its all the sensors damaged at once. Possibly the rear bumper has been taken off at some time and the sensor wire not plugged back in.
Look in the boot and remove the right cubby storage box. There is a small controller about 4" x 4" with 3 plugs on it. make sure they are connected. If they are thne get under the back of the car and check the connectors on the rear sensors

It will be wiring problem or connector.

Open circuit means that the car is unable to see the sensors. Most likely a wiring fault between the control unit and the sensors, check for damaged wires and/or connectors.

Hi think the large unit at the rear is the control unit Audi, WV, Skoda, Seat part number 4H0919475H (http://www.oemepc.com/tvn_result/search/tvn/4H0919475H) try this link to parts web site. Item code appears to be. 4h0919475h the last letter may change but think the rest is the same.

http://www.oemepc.com/audi. Select your year then find the control unit, that will give you the part number and an approximate location from the drawings.
