BUY WD40 CHEAP HERE: ebay.us/WrmBQc

You wouldn’t believe. I sold my Hyundai Tuscon to a dealer yesterday. The car hasn’t been collected yet and still in use. Guess what!? The parking sensors stopped working on the day I sold it!!! Just used your WD-40 trick and they are working perfectly again. Cannot believe what I am seeing! Thanks a lot!

I used a portable vacuum (18v Milwaukee) I put the hose on the blower side of the vacuum and used a crevice attachment (this increases the speed of the air) and aimed it at each sensor while varying the angle of directed air and it worked. No direct contact between the vacuum attachment and car panels/bumbers.

I was very skeptical of this but decided to try it on my 07 Silverado. My wife had washed my truck and I had not driven it for 3 weeks since I was away for work. When I turned it on I found the Service Park Assist message and found my sensors were not working. When I saw the price for each was over $200 I said what the heck, it can't get worse. But to my surprise after spraying all 4 of them with WD40 and turning on my Silverado, the sensors started working and the message no longer came back. Thanks for the trick!!

Worked straight away on my Vauxhall Mokka CDTi. No more annoying flatline beep. Amazing, thanks 😊

Honestly I've been chasing a supposedly bad rear sensor on my 09 Ford Smax, computer said it was the rear right sensor, removed it and swapped it with the working left rear, same thing. Chased the cabling all the way to the sensor control module and tested everything for continuity... All fine. So i be assumed I'll need a new control module at 225 quid from ford.... Balls. Sat in the bath hunting for other fixes, came across this video. Doused all the sensors in wd40, wiped and doused again.... Put her in reverse.....bugger me it works. I can't believe this fix works. Thank you so very much!

Been dealing with this issue for several months now on my Buick Lucerne. Thought i was going to have to get new sensors ..This worked for me instantly. Thanks champ 💪🏾

Great tip, I own Vitara 2018 and facing same problem, I visited Suzuki 3S and they asked $ 206 apart of labor charges with one day vehicle to be parked in garage. Really thankful to you man. Zee Zee Pak

Did this on my challenger, just went and washed my car and my sensors stopped working , went and bought the WD-40 and it worked.

Just tried on Astra. Works a treat. Thank you

This worked on a 22 Black Edition Ridgeline, thanks! Front passenger side sensor stopped working properly after a rainstorm but the driver side worked still. All work as intended now!

Thanks a million, this really helped me. I was so annoyed when they stopped working!

Great video as always George, thanks for sharing!

Land Rover wanted £450 to replace my sensors. WD40 fixed them in 10 seconds . SUPERB CHEERS

We've got 2 cars with the same problem, your method worked on one but not the other. Thanks for that, much appreciated :)

What a simple trick! It worked on my 2008 Toyota Sequoia instantly. It has been fussy this winter. I tried washing and drying the front sensor, thinking it just got a bit dirty without success and the new sensors are very spendy. I sprayed it liberally with WD40 and the sensor alarm went away immediately. Thanks George.

You are absolutely a legend. I had for a month this problem and the things you said made sense for my problem, fixed it. Thank you

Worked like a charm on my A6! 👍

Just tried it on my Volvo S60 and it worked on a sensor that was cutting in before anything was there, brilliant.

Thanks man! You made my day ! It was super sensitive for many months and now it works as it should! God bless you

Tried and proven worked! Thanks loads! One of my sensors have been crazy beeping when there is nothing near it for a while now. Now it's working as it should. Thanks again!

Thanks for this mate. It’s done the trick 👍👍👍

Thanks for this information. I was reversing yesterday (23.12.22), watching the camera in the car. Unfortunately my sensors wasn't working, I was relying on them (beeping) there was no beeping. I hit a car bumper. Thank God nothing serious happened, not even a scratch. The lady was very very furious 😡I told her sorry a million times.. Told me she was going to ring the police. She took photos of my car and I did the same. I'll certainly use the WD40 to clean my sensors. Thank you V much.

OMG! I tried it on my ford s-max rare parking sensor! Now it's working again like a charm! Thanks for this fantastic tip! Cheers

Many thanks for this it’s worked!! I came across this when looking for a video on how to remove my bumper thinking I need to replace the two which weren’t clicking, but all working fine now!

Did this on my 18’ Cadillac Escalade and it worked immediately! Thanks for the post! Front and rear sensors were not working at all prior to this.

Great tip! Also you should spray WD40 on the spray bottle trigger.

Mate , my Jag xf parking sensors stopped working properly the rear ones , I said to my Mrs , I will give it ago , it only bloody worked, top man thanks 🙏

I try it this morning due to ice build up on top of the sensor it works...very informative thank you so much brother...God bless...

Hey there! Hitting you up from the US, I just did this on my wife's 2012 Ford Focus and it worked like champ! I used Tool Box Buddy spray fluid rather than WD-40 but they're all pretty similar. Sprayed it down, cleaned it up and waited a while to let it work. Tried it a couple of hours later and the problem was fixed. On the Focus the sensor made a continuous beeping sound rather than the repetitive chirp and now it functions like new. Thanks for the post, I'm sure the shop would've charged me at least $200 for that.

Amazing ! Here I am getting ready to pull my front bumper and I stumbled on this video. IT WORKED!!

Best quick fix ever! Thank you 😀

Great thanks , I've just done that and it worked 👍👌

You have solved in 5 minutes, thanks to your video, the problem I had with the sensors of my Mercedes CLS W219 !!!! THANKSSSSSSS 😎🤟

Thank you, this really works, tested on Peugeot 508 SW 2015! Haven't drove our car for 6, 7 days. Car was outside under the car cover and past 6, 7 days we had all kidns of weather condition: snow, rain, light winds, up to -8 Celsius over the night, few sunny days.... Yesterday decided to take out cover from the car, it was below 0 Celsius and because of rain, snow, sun and cold, there was a lot of snow on the top od car cover and car cover was like a cardboard paper almost completely glued to the car. We had to use a lot of water temperature around 25 Celsius (never use hot water, glass could easily brake if it's really cold outside!) to "soften" the car cover. Finally we did it, car cover was removed. Some half an hour later tried to start the car, it started without a problem but on the main screen car gave us a worning that something is in front of car but in front of the car there was nothing at all. At first we thought some of the parking sensors on the front of the car got faulty. We took a short drive and every single time we stopped car gave us a working that something is in front of the car really close, it was so anyoing. Did some research and found your video on KZfaq so decided to give it a chance. My WD40 bottle was almost empty so I had to use something else: cheap W5 lubrication spray from LIDL, not as good as WD40 but I had nothing to loose. I've sprayed all parking sensors in front and on the back of the car two times each, it was still cold outside, left it to soak for a half an hour. Started the car and: voila, no more parking sensors warning! Wife did a few circles around the car, 50cm to 20cm from each parking sensor, to test if all car sensors are working propperly and they did, problem solved! Guess some amount of ice formed around one of few front parking sensors, they were "thinking" there is a close obstacle in front of the car. All in all problem solved, no more parking warnings yesterday or today, hope it will stay that way. You've earned yourself one more sub, thanky you!

I honestly cannot believe that worked. My Model S's sensors started going bonkers the other day after a wash and I tried this hack and boom lol. Saved me hundreds... thank you!

Great tip. Thanks!

Thanks for the video George, I'll let you know how it goes.

Dear George! Many thanks for your video and your know how, you saved my money (EUR 180,00). I've had the same problem with my VW Tiguan, the dealer changed the sensor a month ago, after one day with snow and water on the highway, the problem was the same. Now it works!!!!! Thank you very much, Andi

Wow so simple! Was very sceptical that this would work but IT DID! Thanks very much for info

Spot on. 2014 ford Cmax with "Parking Aid malfunction. Service required" message. Spayed the rear bumper sensors with WD40 some crud also came out. But back to normal working. Great fix. Thanks for posting this video. How many drivers have put their car into the Ford service centre without trying this hack?

Brilliant ! WD40 trick worked instantly to fix the problem on my 2016 Octavia estate. Many thanks!

u always come up with good videos bro

Worked like a charm. I had given the tailgate a quick spritz with hose the day before . Lesson learned . Thanks 1.9 Trillion👍

Just did it on my 2020 Iveco Daily. Worked like a charm. THANK YOU so much!!

Any idea if this will help if the sensor was painted over during a bumper retouching? Thanks!

tried and worked, unbelieving, you are genius! Thank you so much!

My reversing sensors stopped working, didn't even know about the switch to turn it on/off, I had caught it by accident and switched it off, thinking how much this will cost to repair, so a great bonus to turn it off and everything worked again. Thank you.

THANK-YOU! That sensor alarm was driving me crazy when I backed up. I must have had water in there after I washed my truck. This worked on my 2014 Nissan Frontier.

this didn't work initially but after letting it sit for 10 minutes and giving it another blast of WD it did. Thank you!

This is very very good. Thank you so much didn't know that.

If you install an aftermarket parking sensors, will it pass the MOT?

Great tip! My jag x350 fault is fixed…thx a bunch

Thank you wery much ! Good job ! Feel good video for everyone

after an awful snow storm my car started doing this hopefully it works Update: problem is gone I have a Dodge Durango works like before thanks 🤩

Thanks for the valuable tip- Had problems with the camera in the back of the car-- did not work at all- used WD40- after 1 hour it worked perfectly again. 6 euros for WD40- we saved at least 500 euros on your tip.

My Hyundai ix20 sensors were on permanently (no beeping). Was going to take it to the main dealer and expect a huge bill as usual. Saw your video and hey presto, worked like a charm. Thank you for the video.

EXCELLENT VIDEO!!!!

Great video

my sensor keep beeping when i stop, thought there are no inteference in the front.

That WD-40 trick worked for me on my 2013 Cadillac XTS. 👌🏽

Awesome, it helped for my lexus rx 350 2010

Washed the car, new car, after two days censor would not work followed your instructions and wow!they are now working Thank You

Just used this tip and fixed my annoying warning flatline bleep. Thanks! 🙌 (Mercedes CLK 2003)

Worked perfectly thanks very much 👍

Good vid mate

so happy! it worked! my VW Touareg 2006, rear sensors are working again woohooo!

Thank you very much. My Vauxhall Mokka was giving "Parking Assist Temporarily Unavailable" and giving a loud Bong sound every time I started the car and every time I came to a halt. It was driving me nuts. I sprayed WD40 into the sensors but it did not fix the issue straight away. However the next morning it was working perfectly.

Going to give this a try tomorrow my parking sensors went quieter then they now don’t bleep at all

Nice and simple 😊 Thanks

Thanks for sharing this tip, it works!

Amazed! Works perfectly

Awesome worked a treat, thanks.

Thanks 🙏 George

How do i know if i have rear sensor ? Because i have the little dots on the back side but it never makes the biep noice when i drive backward. On the frontside it beeps very well ? I have rear camera. Is it possible that i dont have rear parking sensor?

Man I love KZfaq. Cheers brother.

Worked on my Ford Ranger. The night before was a deluge of rain, had an issue with the passenger rear reverse parking sensors. After a quick blast of WD40 and waited a few minutes and it sorted out the issue.

Thank you!

10/10 tip it worked on my audi Q2 which stopped beeping when put in reverse, it only had one long beep instead of the frequent beeps alerting me of distance to an object. after cleaning with wd40 it started to work as normal

I tried this as my sensors were continually beeping but it didn't fix them. But then a few days later they started working again, thanks for the tip!

Hi do you what is the problem if my camry reverse sensor has the electricity feeling when I put my hand at the sensor indicate that it work but it didn't work

Brilliant, simple fix, red light on one rear sensor every time it rained, VW Golf mk 6, one quick spray and fixed ..... thank you.

Thank you for the tip! Worked wonderfully well on my Ford! :)

This worked for me! Thanks!

Hello, I sure hope you can answer this. I bought a used Venue SEL 2022 last December 2022 and now the sensors that go “beep beep beep” when I get too close to the car in front of me makes that beeping sound and I like that. Now the beeping stopped I can’t get anyone to figure out how to get it to work again not even the Hyundai corp office. I sure hope you can help. Thank you.

my sensor cap fell out and now thw system in the car is saying parking assist error, would I need to buy a new sensor ?

Can Q20 be used instead?

WOW!!!....Thanks George I tried this and it WORKED!!...I've had this niggly problem on my e93 intermittently, for the 3 years, now after trying your hack, now sorted in 2 minutes, Thanks again.

Good video George. Thanks

Thank god there's KZfaq, any mechanic would have charged me lots of this 😂

Thx, it works . Fantastic tip

Thanks for the advice it worked 👍

very informative...about to try it...fingers crossed..

Thank you for this, sorted out my Hyundai i30 in minutes and the guys at the garage had no idea! Cheers.

Would this work when it’s detecting something that isn’t there?

Rear parking sensors on my car were working fine until one car bumped into rear bumper and after that the sensors stopped beeping and also no red light on the parking switch inside the car. Can WD 40 solve this - there is no damage at all - it was just a slight nudge from behind - appreciate your thoughts on this one - thanks

I think I have ice behind the sensors. We had heavy rain then bitter cold for 2 days and my sensors are flatlining. WD40 probably wouldn’t work on the ice?

mine seem to beep when there is nothing around. It has been raining nonstop here for a couple of weeks now (australia) . would the water also make them beep? thanks

What about if the sensors are over sensitive? Mine beep when I am nowhere near an object.

thanks for that it worked
