One of my parking sensor's packed up before christmas and i have only just got round to changing it,
This DIY is broken into 4 sections:
1 - Broken sensor identification
2 - Rear bumper removal
3 - Replacing with new sensor
4 - Fault finding (further down page)
I only used a few tools:
1 - Broken sensor ID
This is the easiest part, turn your key two 2, so the engine is OFF but the lights and heater is on. Select reverse and go round the back, with your head at bumper height you can hear the sensors clicking, all four sensors should click, the one that dosent is the problem
2 - Rear bumper removal
This is quite simple and took around 30 - 45 mins
Firstly i ran my car up on to two scaffold boards just to lift it up slightly, you can do it from the floor but its a bit of a squeeze
there is an expanding rivit in each of the wheel arches that needs to be removed, the pin pulls out then the rivit, a trim removal tool will help but screw driver is fine:
Then above the rivit in the arch there is an 9mm bolt
Under the back of the bumper next to the exhaust pipe there is anouther expanding rivit that needs to come out:
There are two 8mm bolts and a 10mm nut under the back of the bumper near the exhaust pipe:
Then three 8mm bolts and a 10mm nut on the other side, the whole black plastic bit will now come off
The deffuser can now be removed, it is just cliped on, start at the exhaust pipe and pop the clips out from the back of the bumper one at a time, circled in red, there a few clips.
it just pulls off
There are two bolts with a star head that need to be removed. one each side
Once the bolts are out the whole bumper pulls towards you and off, watch out for the parking sensor wires, they are cliped up and can be uncliped so the bumper can be moved
To replace, reverse
3 - Replacing with new sensor
The wire can be removed easily from the sensor, there is a clip that needs squeezing on the bottom side,
With two flat head screwdrivers you need to pop the two clips either side of the sensor while pushing on the sensor from the bumper side, it will pop out
My new sensor was black,
So i sprayed it to match the others
Pop the new sensor in the same way as the old one came out, push the wire on the back
If you flip the bumper up right so that it istn facing the ground, switch the car to 2 again select reverse and you can check that your new sensor works :thumbsup
Thanks for reading, I hope this helps someone
