FAULTY VW GOLF Rain Sensor - How To BYPASS
ฝัง
- เผยแพร่เมื่อ 29 ส.ค. 2024
- In this video we show a simple workaround for your Volkswagen Golf Mk5 Rain Sensor not working properly. It is very easy to disconnect the sensor so that you can manually work your intermittent speed on the wipers and manually control your lights as well. In this car the wipers have been 'playing up' for years. In fact from memory they have never worked properly.

Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.
Vince, when you removed the sensor circuit board you actually just took the back off the sensor housing leaving the front of the housing in the bracket. You should be able to pry out the front also which will remove the gel piece with it leaving a clear gap. Whenever the gel goes bad it’s best to replace the sensor to get new gel as it’s needs to be transparent in order to detect light and movement of the rain drops.
Years later, your brother sells his car to a person with a repair channel who finds the disconnected wire... thus the cycle repeats.
Vince, appreciate how you help fix things for your brother and how well you two work together. It’s brilliant. That’s what family is about mate.
I love when you’re brother makes an appearance
Perhaps we can have a revisit one day with a proper fix, that would be awesome.
I got a golf Mark 5 for over 10 years now, amazing car! A couple of years ago i had my windshield replaced, and the sensors werent working as they should, turned out there is some kind of gel between the glass and the sensors, replaced that and it worked perfectly
As a windscreen tech I see this all the time. The sensor can be separated from the screen easily by using a flat head screwdriver either side where the backing plate separated. The silicone gel pad has got air bubbles behind it. Very easy fix with silicone gel
Exactly 🙏
Went to a few of these as a trainee windscreen tech, as said the gel is separating from the sensor to the screen.
IIRC the aftermarket screens we'd get from Laddles didn't suffer as bad from this.
Thanks Vince - A VW fix is much more helpful to me than vintage Rolls Royce fix🤓
So nice to see brothers working together again. Good times!
LOL ONLY VINCE CAN TURN PULLING A PLUG OUT INTO A 20 MINUTE SAGA! KEEP EM COMING BUDDY - MORE BULK RETURNS PLEASE
In this video, as in many others, your choice of background music is wonderful... the sometimes used 'Golden Things' & other tunes are a shot of relaxation.
The entire sensor does come out. The frame around the sensor is mounted to the glass and is the anchor for the mirror.
The "white" diamonds is the separation of the gel pad between the glass and the sensor. The can shrink and become brittle over time. The new sensor you showed on Ebay had a new gel pad on top. The 4 diamonds were black on the new sensor because of the gel pad making proper contact.
I agree typed my message using fingerprints on sellotape as an example, as similar type of description. then I seen your message after posting my message.
I had this on a nearly new Skoda Octavia, with lights on auto they would often come on in bright sunshine. Took back to Skoda dealer and after initialy saying it could be a bad earth, they then said the 'auto' lights feature was actually meant for tunnels in Europe, where a road may have several tunnel sections - it wasn't meant for lazy drivers to just leave it in that position so they didn't have to manualy turn the lights on when it was dark enough - so they weren't going to do anything about it. Never went back to that dealer.
the white is actually air bubbles in the gel, it should be perfectly flush with the windscreen and have no bubbles at all, that is what the problem is the sensors can not see though the air bubbles.
Nice little fix. I never use the automatic settings on the wipers. Lights yes, because it's easier. If it's foggy or I need full beam I have to do it manually of course. My Girlfriends car does even switch the full beam on and off automaticly.
I have the same issue with my Mk5 Golf. Thanks for the video as I will be doing something similar to my car. However the light sensors work well but the wipers are pot luck. So I'll try and partial disablement of the sensors.
Replace or get the gel replaced between the sensor and the windshield. Easy and cheap fix!
Maybe it's different on your brothers Golf MK5, but on both of my GTIs it's different.
1. When you put the setting "off" the wipes won't work. And that's logical because "Off" is off. You have to put it on the setting intermediate (1 position above "Off") and there you can choose the sensitivity.
2. When the Golf doesn't move and stands like when it's parked, the wipers won't automatically work. You have to drive and reach over 15Km/h, at least one time, so that they start working in the intensity/sensitivity that you chose.
But what you did is still a nice workaround. 😊👍
Yes. This is the same with my Ford Transit.
Well done Vince and Paul great fix
Vince..i also drive a VW but alot newer...all the diamonds in the sensor are black...mine works perfectly...i had a windscreen repair and the man who repaired it replaced the sponge that fixes to the windscreen...its crucial that no condensation from the windscreen enters the sensor, a good fix would be to use a strong double - sided tape and re-apply to the windscreen.
I would say it is more like fingerprints on sellotape Vince, whereby after you remove your finger then the tape turns white. but when applied to something like glass the fingerprint doesn't show up quite as much, so my suspicion is the sensor pad has come away from the windscreen which gives it the misted look.
Not sure this was a fix but I can identify with the issue, one of mine (a ford focus) is temperamental with its rain detection. Also, you’re not mimicking rain, it needs drops and force but that’s probably inconsequential. No advice here because these sensors are a nightmare.
Keep up the good work and, as always, stay safe!
the thing that causes it is like fingerprints on sellotape, then not quite so visable when compressed onto glass, it is the gel releasing it's grip on the windscreen, heating the glass up and applying pressure from the mirror side should allow the gel to demist it again. unless you can actually get to the gel pad, which applying pressure, and heat from inside the car would be better,
Vince has a Porsche and a Bentley- ooo weee 🤣
You should use led light when testing light sensor. Halogen color and bright isn't enough. You get answer for the gel but also problem for your test prosedure. Wipers sensitivity use also speed information in one of many parameters to wipe.
My Mate Vince goes 4K. Nice! 😃
Thanks for the awareness about golfs.
Great stuff! Oh the comedy - a VW advert came up whilst watching lol!
😂
"White diamond" is a gel with which the sensor works and sticks (if there are, for example, air bubbles, it may be the reason why the sensor does not work)
You could just code the car to no auto-wipers and none of this would be necessary
Would have been a boring video though right
do tell me how?
Thanks for sharing, Vince. Your brother is very handsome with his beard!!
when you first took the rear view mirror off it wasn't actually slid in the grooves properly, the rear view mirror actually pushes the sensor against the glass, so if this isn't pushed on properly the sensor wouldn't be able to read fully. Windscreen technician with 5 years service so far. also the metal bracket is glued to the glass and I would advise not to remove this . the gel pad holding the sensor against the screen gets baked on with the sun which is why it didnt come out and split in half.
eek, in my skoda (part of VW group so they use the same parts bin) you have to move the wiper stalk up to the first notch for the auto wiper mode to be engaged - not sure if the auto wipe feature should come on if the stalk is set to the off position.
companies add these silly things to cars, how hard is it to just turn on lights and wipers? it's just more things to go wrong.
Another great video Vince
My 2017 caddy auto wipers has a mind of its own , does my head in I would love if I could disconnect and use it manually.
Fix or not but interesting to see the light sensor / rain sensor in this Golf and how to bypass it.
My car has only light sensor for the automatic lights on top of the dashboard, but no rain sensor, as it's lower spec Kia Rio, LX trim level. Higher EX trim level would have the rain sensor as well for automatic wipers. My car has adjustable timer for the intermittent wipers so that's good enough for me.
It's air Between the contacting gel bad/mat and the Glass that you see and it shouldent be there as it now cant see the water on the glass and thats why it dosent work.
Here in Finland you have to drive your car with hedlights on, even the 24h sunny day that we have ones a year at midsummer. No matter is it day or not. so the automatic is for lover voltage/dimmer headlights or different "Daytime Runing Lights"(DRL) that some cars have.
Vince, you’re amazing!
AFAIK you could achieve the same workaround by removing the sensors' fuse
Have a similar prob on my older jag, only it's occasionally. The map lights however come on and off at the slightest change in light, a dappled road is a nightmare. I fixed this once but, in doing so, hit the Jag DIY sensor which put the car in limp mode ... I just ignore them now.
NB some of these sensors are linked to the speed of the car, they won't activate if the car is stationary.
ive been trying to diy myself my arctis pro headset right side kept cutting out intermittently took it apart and you cant even access the speaker area to repair it and the solder is so minimal crazy how much they cheap out nowadays lost cause looks like
Hello. Could you tell me the number (designation) of the wiper relay in your car? Thank you.
I had 2005 Nissan micra se plus which had auto wipers and keyless Entry wich was hit and miss when they would work the locks were always Making buzzing sounds the hole car came with problems from new the only thing that was eny use was the sunroof which was great in warm weather my Current car, Vauxhall Astra J has mostly all manual everything the wipers are the best I have and on Any car I have owned the the Intermittent has plenty of speeds to select from all done with a twist dill on the stork
auto wiper and headlight does bother me a lot
i have pull ceiling and disconnect it and throw it out the windows lol
i always love it stay manuel just like classic vehicle no computer at all
Thank You so much, Vince and Paul. I don't have 'automatic' anything, and *I Love it!*
When the World One lives in is ALL 'Automatic', what will the *Spoiled* people do when that's taken away? lol
You should also fix the streering wheel. It's on the wrong side.
Often it’s just the gel pad between the sensor and the screen, easy to replace and fix
Your brother's car has a leak I suppose? Dashboard being full of silicone bags to capture moist,
Try cleaning the board with ipa.😊
No need for a rain sensor in Great Britain, it is always on anyway.
i'm going to do same repair to my Skoda Octavia, I don't like auto wipers at all.
Try a new gel pack 👍🏻👍🏻this is quite a common thing
You should be using vcds to check what’s wrong before just unplugging things for sure.
In my golf mark 7 if you go to settings, car settings you can turn the automatic wipers off. I personally find them very erratic. It'll come on when only a really mild drizzle yet not come on sometimes when it's raining hard. It's not the best system. Not that I've seen a good system. The one on a BMW makes the wipers run so irregularly makes one feel sick! Rather than the usual rhythmic pattern it's like an irregular heart beat!
Why was this issue not adressed under warranty?
Hey Vince, You should look into the CAN Bus system the car uses to communicate back the BCM on that car. Its not whats wrong but the network that is running in side that car is super interesting. That sensor has power, ground and a data line. The micro controller joins the "network" of all the other devices. For instance the wiper and headlight triggers aren;t even standard circuits. They are powered and when you move the knob or whatever the stuff is turned on via software. That's the way most cars are now. I have a 2011 Audi A4 and a cable, once you get into the network you can do all kinds of fun stuff
This will also apply to Audi, Skoda and Seat cars.
What was wrong with getting this sorted under new car warranty.
Hate auto headlights. Many drivers on the interstate at night with only daytime running lights on. Very dangerous. Auto wipers seems very stupid, especially in freezing climates. I do like auto-dimming mirrors, though. My 2000 A4 had it and although I had to replace all three mirrors after 10 years, I miss the feature on my 2008, which is lower spec.
Nice work vince
The steering wheel is on the wrong side.
Can you fix this?
Update the ECU?
When replaced these sensors need a calibration!
Bloomin Germans
Do you think your brother would fancy a Rolls Royce?
You can get the part £15 was it worth the bypass.
Will it destroy the mot
It wouldn’t be tested as part of an MOT, as long as the lights and wipers work when manually switched on
Also I’m sure the light sensor is on the back of the mirror 🤔
Don't forget that auto lights are useless in fog. Because there is still lots of ambient light just no visibility. That said I do like my auto lights. Less so my auto wipers.
If you know a friendly autoglass man theyll fit one on the cheap
Don't cheap out and fix it🎉
The Sun is 120,000 lux in direct light. that torch is scraping 20 lux
11:36 Don't use metal wire or fishing wire. Use very cheap dental floss, it works a treat.
What is the song played at the end?

Faulty. VW. Golf. Rain. Sensor. How. To. Bypass
If you get 1 million subscribers your buying a new golf lol
Rain sensitive wipers use capacitive sensors like the touch screen on a cell phone, so it detects the presence of water on the glass. it's a pity your brother is a cheap skate and didn't replace the sensor, it would have made a better repair video.
But typical of anything VW makes electrically. Door locks, steering wheel angle sensors, radios....... You name, it breaks.
The horror of manually turning on your headlights!!!!!
Ps 15 year old Honda more reliable than a 2 year old Volkswagen 😢
Interesting video but, I think you need a new camera man😅
VW’s rain sensor is the worst in the business by far. Get VCDS and you can disable the auto settings without having to remove anything
Auto rain sensor ?
What a joke. Seriously, how taxing is it to turn on the wipers manually when it rains ?
The Golf is totally damaged, the steering wheel is on the right side.
This was my first thought, too. 🤣👍
@@batluckies Fun must be.
@@winny6892, absolutely. 😁✌️
Why not giving Paula new hedge unit and putting it in his car because that looks like the dogs yeah the dogs looks like from Peter Lambeth. Ha ha I need one like a poly pole. Omak two and Ali has not has have a Walmart card.
I had a few VWs but I won't get another one, massively overrated cars. Toyota are much more reliable.
im a kid i dont have that car...
That car is a lemon; they even installed the steering wheel on the wrong side of the car.
Auto-lights and auto-rain sensor have to be the DUMBEST features ever. Take the simplest things and add unnecessary sensors, pcb's, and switches. Yeah, that'll make it better and keep costs down!? The other dumbest thing, at least here in the US, is the DRL (daytime running lights) which typically only activate front lights. Dumb drivers think their lights are on and don't turn them on at dusk or night thus drive around with the tail of the car completely dark!
You should fix it for real, I don't like this video buddy😢
im the 666 like
wrong type of rain lol
Sorry, just noit interersted
Hack'n with frick and frack ! 😵🤦♂️
