parking sensor

[kmthor]

Hi Guys
With a replacment parking sensor do you have to get a colour match or does it just fit in behind the bumper?

They are supplied unpainted and need to be painted to match the car. Depending on which sensor has failed, the bumper may need to be removed to get access. I've replaced the passenger front on mine, access was difficult but not impossible with the bumper still in place. Both the centre fronts require bumper removal, the drivers front will need the airbox removing to get access. I've left mine unpainted for now, so I have three silver and one black in the front.

Genuine new replacement sensors, which is the one I purchased.

Do not be fooled by those visible clips, the whole sensor is completely bonded and sealed and the only way to remove that front part will destroy the sensor.

It just needs a good reach around for the rear sensors and undoing of a couple of screws that hold the middle of the bumper underneath, I had 2 sensors knackered when I picked my car up, bought some paint off ebay and it came with primer and lacquer, sprayed them up myself and put them in the oven on low heat to cure, don't lay the paint on too thick as itll effect the sensor, bit of G3 to flatten the lacquer and shine it up and they where good to go, they weren't a perfect colour match but mine being Aqua pearl blue iirc would be harder to just match without comparing anyway, but it's hardly noticeable being just the sensor and I can live with it, you can only tell if you look for it.

I just installed the rear left sensor had to unscrew three screws in the wheel arch the then ease the bumped out just the clips then i could get my arm in the back of the bumper which let me get the sensor out. now the for the headache getting the bloody plug off this took me ages as there isnt enough wire to get it down to a good working level there is a little clip on one side that causes the sh1t. anyway finally got it off with a screwdriver you have to be careful tho not to break the plug. once off the new sensor was in place and the bumper back in place in 5 minutes
