Parking Sensors Fault

[Lark yelseb]

Help Please chaps

 

I have a Mk2 Galaxy 2.3 petrol X reg

 

Parking sensors not working. 

Upon engaging reverse we get one beep and then the sensor light just flashes.

 

How do i go about diagnosing the problem??

[chrislloydie]

Does your car have front and rear sensors?

 

Do you have vcds lite? That'll tell you exactly which sensor is faulty.

 

If not, you can listen carefully to each sensor and hear a very quiet ticking. Any that aren't ticking are faulty. Just one faulty sensor will stop the whole system working.

Brand new sensors on ebay for

Check under the front passenger seat for water.

great will have a look under the seat.

 

i do have front and rear sensors. i will try and check the sensors.

 

are they easy to replace if they need it?

[chrislloydie]

Very easy, especially the rear ones which can be accessed by lying under the rear of the car. They unclipped from bumper then unplug electrical connector. If you find a faulty one, check along the wiring for breaks. Or swap sensors over like I said earlier to rule out broken wiring.

[Lark yelseb]

identified one sensor that is not working.and it is on the rear so not so bad i guess.

does the sensor have to be re wired all the way back to the module under the passenger seat?

[insanitybeard]

No, each sensor has a multiplug connector so the sensor is completely independent of any wiring.

Did you ever sort this? I have the same problem...

Note, back parking sensors should chime from the rear when reverse is engaged (found behind left hand slatted grill, mine was unplugged)

Front parking sensors chime when starting up and pitch is totally different.

 

ECU for parking sensors is under the passenger seat, if it's wet the rear washer pipe has leaked as its joined inside the car at the top left area of footwell under carpet. (easy fix listed on here)

 

Vag comets is s fiddle to use for this once the fault is cleared
