How to perform a reset of rear parking sensors

I have just replaced a non clicking sensor which didnt resolve my rear parking issue [solid beep after 5 seconds of selecting reverse] so i then went on to replace the wiring loom which i thought worked [bumper off i performed a test it seemed to work] however now back on car it seems to be erratic in its working.....one minute it works...beep...beep...beep then its a solid beep etc etc.
Is there a rest process to perform that i can try......i have seen that there is but i cant find the thread now.
Thanks

hi

is this what ur looking for , how did u get on removing the bumper please, also got to fit a new loom myself



- Find a free piece of road.
- stop the car and turn off ignition.( gear in P )
- start engine
- put the car in low range ( makes it easier, less speed and distance )
- then drive the car, allowing all the gears to got through ( up to 5 )
- stop
- put the car in reverse
- drive 100 or so meters in reverse.
- stop
- switch every thing off
- take the key out
- wait a couple of minutes.
- restart the car
- DONE

Hi Gstuart
Glad someone has spotted the error as i was going to say to you this morning it never worked.

As for the rear bumper removal - its easy just a little fiddly - the hardest part is the removal of the rear mudflaps as the screws are rusty and to get good pressure on them i found best to jack the car up and remove the wheels one at a time! Big Cry

so sequence is as follows;-

- Remove rear mudflaps - three screws in each

- Remove one push type plastic clips from inner arch [one above the mudflap]

- Remove the four screws from under the bumper [along longest edge either side of towbar housing]

- Remove the towbar plastic cover

- Then the fiddly bit - open the rear tailgate and lift the flap which drops down between car and tailgate, with the lower part of the tailgate slightly lifted you will see four plastic 2 part push clips - remove these

- Remove both rear light clusters [2 screws in each and unplug the loom to each]

- Now you will see a 10mm [i think] bolt one either side of bumper - loosen these off but dont remove yet

- next you need to pop both wheel arch trim [lower part only] by just pulling gently from bottom

- Then you will see another plastic 2 piece push clip hiding in a slight indent - remove these [one either side]

- Next you need to pull both sides of the bumper [the part which runs along the rear panel upto the arch] away from the car [directly to you]

- Now you can remove the previously loosened 10mm bolts and the bumper will be simply balancing on the rear part of the chassis

- Now with out letting the bumper fall off the chassis you need to pull the bumper toward you [rear of car] on the nearside as this is where the wiring loom is plugged in

- If you spot the cable from the bumper you will see that the plug [connectors] are screwed to the body

- you need to flex the side of the bumper down and then remove the screw

- Then you can pull the connector apart [one side has a clip which needs pressure on to release as you pull it apart]

- Once un-clipped simply pull the bumper directly to the rear end of the car and it will come away

Try and lay the bumper on a dust sheet or something soft as it will scratch easily on concrete or tarmac drives etc

- You need to push the top bumper trim from rear edge of bumper toward the inside edge of bumper which will then allow you to pop the trim up leaving the clips in place along the inside edge of the bumper, to then remove the trim you need to pull it up vertically away from the bumper and the trim should pop away one clip at a time......

- This will expose three large screws with a 10mm head/torx head - remove these [they hold the internal wiring loom foam in place]

- Flip the bumper over and remove the foam - the loom is pushed into this

- Then remove the plug from each sensor and remove loom

Now your ready to replace and reverse the procedure

Good luck Thumbs Up

Do you have trailer sockets? Because if the car is configured correctly it will disable the rear sensors if it thinks a trailer is connected.
Was it a genuine sensor you replaced? I’ve had issues with cheap ones...

You need an IID tool or similar really to see what each sensor is doing

yeap.


something like live data, parking?, then you have to select the 4 rear sensors.

Put it into reverse etc. (probably handbrake off too)

It reads 2.5m for not sensing any obstruction.

No worries, there is so much stuff to remember with these cars. It's all on the forum somewhere, but finding it isn't always easy! Thumbs Up
