All information and direction on this is pretty on point. I also appreciate the fact that you stated the issue, addressed the issue and concluded with issue resolution without 10 minutes of unnecessary off topic rambling that many other how to videos are guilty of. 10/10 my man, excellent job.
Dear sir I've worked for Volkswagen for 30 years. This was a recall. I recommend you use dum dum instead of silicone. Also the battery has two drains blow it that you have to take a large dowel and knock the rubber grommets out. And the last part of the recall is take the sunroof drains and cut the ends off with a pair of scissors so they flow better.
Dude, THANK YOU SO MUCH! I've had my '02 Passat GLS sedan since I bought it new. For the last several years, as soon as it gets cold out (I live in Upstate New York), not only does the car randomly go into the dreaded "Limp Mode" on super cold days, but the windshield frosts up on the INSIDE every day. And when I say frost, I mean frost! Sometimes it's so thick I have to run the defroster for half an hour or more and then wipe the windshield and dash down with paper towels. What a pain! I knew there was a water leak, I could feel the wet carpet on the passenger side and I know the TCM is there. I searched many forums years ago that all suggested it was the sunroof drains. I cleared them all out with thick weed trimmer string, but still had the problem. The only thing I was able to do to control moisture in the winter was hang several bags of moisture absorber in the car (the kind they sell for damp closets and RV's). It didn't solve the windshield frosting issue, but the car went into "Limp Mode" a lot less. We recently had Tropical Storm-level rain here, and not just the passenger footwell carpet was soaked, but the floormat on top of it too! I did a Google search and your video came up first. Now, thanks to you, I finally have the solution!! Your video was very clear, well-filmed, and concise. I like that! Would really love to shake your hand and thank you, because this has been such a huge source of frustration for me - - I always dread the coming of the cold weather because of the trouble I know I'll have with the car. I'm going to get to work on this ASAP, though I'm a little frightened to look under the passenger side carpet for what I might find. I may have mold under there. I also appreciate the other commenters to the video that mentioned removing the wipers and cowling to get easier access to the cabin air filter housing. I may try that. ONE QUESTION: What's that blue doohickey you use to gently remove the interior trim, and where can I get one? Again, THANK. YOU. SO. MUCH. You're the boss!
You should be good if you use the butyl, I have used silicone on alot of other waterproofing projects and it always work well, that's why I chose silicone over anything else.
I'm happy you got value from this video and thanks for watching! Yea, the water leak in the footwell can be a real pain. I had to do alot of digging and diagnosing to figure out how the water was getting inside the cabin. If there's mold under your carpet, you could use white vinegar/water solution to spray on it. Vacuum then use a large fan to dry the carpet. Make sure it's dry before you lay the carpet down again.
I just did this to mine Passat, holy crap... that plastic cradle is ridiculous. The only thing you didn't show properly, and I was like... this isn't that easy. It took me 4 hours!!! I cleaned everything and seal it like you did. That rubber gasket isn't rubber...but some kind of foam...Why??? Why they did this??? I don't understand. The same bs is that front motor mount... foam crap. OMG. Well, its done now. I started to have wet passenger flor and water destroyed my cds in the glove box. That gave me a sign to go to Ytube. Thank you so much, you have the best video out there.
Thank you for sharing this informative video on a not too uncommon problem with the Passat. As you point out one of the main reasons for this water problem is the accumulation of debris in and around the fan box. May I suggest then that we should pay attention to that area of the car annually to clear any leaves and other debris that tend to accumulate there. One of the best ways that i have found to help is to use a leaf blower, gas or electric, to clear out those problem areas especially in the corners of the battery compartment. But, I am glad you have found a more permanent solution to water entering the cabin of the Passat.
Man, thank you, i did it on my passat, the holes under battery were being closed, my english is bad i know, but i wish you all the best, and thank you.
I did this job on my B5.5 two years ago, top tip.. It's a lot easier to do this job if you remove the windsreen cowling, but you need to remove the wiper arms to do this.. 13 mm nut on the arm pegs... Once you remove the wiper arms remove both of those torx head bolts that hold the plastic inserts by the bonnet hinges, either side, there are also two clips to remove that hold the cowlin in place just on the underside below the windscreen... Once these are removed just gently lift the cowling up and away from the windscreen, there is a seating grove that it's snapped in to but it will just pop out.. Remember to be gentle as you do not want to split the cowling.... re-fit is reverse of removing.
Wonderful How-To video for leaks. At about 11:14 he gives us excellent lesson on removing inside trim pieces to get under the carpet to dry it. Don't miss that! If Owners would keep their car cleaner in that area and keep the debris out of that corner pocket, there would be no leaks. But, if they park outside under trees and such, it can get full of decaying plant material quickly. I wonder if your original gasket was ok, it looked good, just wet from standing water in that pocket. Be sure to replace that moldy pollen filter (cabin filter) while you are already in there!
Thanks, for taking the time out to leave your comment, much appreciated. The original gasket seems ok, but water was still leaking inside, thats why I decided to permanently seal it with silicone. Yes, definitely replace the pollen filter at this time while your there.
I look after an eldery women who has an old passat like in the video and found the other week no electric window working and passenger side floor soaking wet!! This has to be the problem, she leaves the car under a massive trees which always drop pines and rubbish. I've left a heater in there but there's pools of water underneath and to be honest the last thing I want to do is take out the carpets, any advice on ways around this ? thanks
@@strongteee you could leave a large fan running to blow air on the carpet for a few hours and see if that gets it dry. If it's not dried properly mold will grow behind the carpet because of the moisture.
@@CraftyWorkshopBuilds thank you. Yes it's going mouldy already so will have to be cleaned after. I've left a fan in there to try and dry it out but there is pools of water so the carpet may have to be took up (eeek). Do you think if I dry out the carpet and module the windows might work again? as they currently aren't but the sun roof electrics are working. Any advice is so welcome. Thanks
If all else fails check the rubber grommets are in place under the floor. I had one missing under the left side and didn't realize. Sealed the window regulators, cleared plenum and sealed pollen filter housing anyway
Thanks for the informative videos. You have to wonder about the engineer who came to their boss and said "hey boss, you know we have been looking for places to put the CCM and TCM?"
I work for Volkswagen win this recall came out. It's not the problem of where the modules are it's the guy who decided to use foam to seal up a watertight seal in the rain tray. Dumdum works much better than silicone. It's like black window tar never dries out
your video helped me immensely. That area around the pollen filter was gunked up, and so was beneath the battery. However, it apparently never flooded my interior, thankfully. I cleaned it all up, pulled the pollen filter box, cleaned up all in behind there, cleaned the grommet beside the battery area and cleaned out the drain beneath it. Prior owner was a pig who never did proper cleaning. Fortunately, my TCM box was dry as a bone, as was the padding and carpet. The module itself just crapped out after 170,000 miles, imagine that! Super simple to pull it out and replace, thanks to your instruction on removing the trim and carpet. Now transmission shifts fine, no clunking down into first at a stop any more. Many thanks for this very well shot video!
Great video! Helped a ton especially the tip to remove the gutter thing. I second a few other comments, flexible strip caulking (aka: Dum Dum) is the best thing to use. Its like strips of silly putty, and stays flexible forever. Thanks for the video!
Really a great help!! I already cleaned out the drain under the battery, which was clogged, but still water came in the passenger side footwell, and I couldn't figure out why? Then I found your helpful video. Thanks again. Greetings from Denmark :)
Great video and to make it even easier is to remove the windshield, wiper cover cowl that the wipers arms sit on and you'll have so more easier access to the filter housing. I used the original gasket and used silicone under it and on top of it and you don't need to use as much silicone and it seals perfectly.
Great video, just bought a 3BG with auto issues. Turned out to be the TCM swimming in water. Have to get a new TCM, but this video greatly helps with stopping the initial leak, thanks!
Fair play you did this the hard way , if you remove the gutter from the window this is much easier to do. This is a case of the bigger the gob the better the job.
I just did this yesterday. Also i checked all drainholes in the doors and threw that rubber grommet under the battery way into my neighbors yard so i never could find it again. Then i ripped up the carpet and put the Defa car heater on and cracked a small opening on the rear windows. I will leave it like that for at least 3-4 days on full heatblast. Best thing i could do was having a heater heat up the floor from underneath but this must be good enough. Its just about to be winter here so there is no sun to dry up either. Just wished i did this BEFORE i had to. I used much more silicone and will keep the leaves away.
Great video. I’ve got a 2003 A6 C5 Allroad so very similar. My bolts holding the filter housing look like they have been cut short before, so don’t hold down the housing, so might have to use silicone to stick it down. I believe there is another drain hole under the ecu as well as under the battery
This is the main culprit. The drain under the battery on the Passat and Allroad gets saturated with debris and makes a huge pool there, making water ingress thru the air inlet.
Great step by step instructions! Thanks a bunch. About to get out to the driveway, tear up some carpet, squirt some silicone, run some fans and see if I can get my TCM dry. I’m getting a torque sensor error on my 2005 Passat TDI that I hope is just because things got wet, not because I need a new tranny at 210,000 miles.
@@CraftyWorkshopBuilds Sucks bIg time. This is my third Passat and the previous two both suffered massive water ingress. This one got to 200,000 miles before it happened. Was my fault. I didn’t clean out the filter area thorough enough after a few years. Should have known better. Anyway, got the carpets up and the air filter sealed with silicon. TCM was AOK inside but the wiring bundle had been soaking along with the carpets. Have had fans and some small gel dessicants on it for two days now and it’s still crazy damp. Clearing the error code is only a temporary fix, but the car drives just fine so I think I’ve got a good shot at fixing the issue with this dry-out. HOT TIP: The rear nut on the cabin air filter housing is indeed tough to get at. But after several failed attempts to loosen it, I found that releasing the plastic baffle that attaches to the windshield allowed me to twist the baffle just enough so that I could get a small ratchet back there. Then the big issue was that there was so much dirt in and around the bolt that I could barely get the 10mm socket to seat on the nut. Had to scratch and brush it all out of the area first.
I had water sloshing around in my TCM housing and for a second was really worried - but we swapped in a 5 speed and got rid of the TCM years ago. Fingers crossed that this fixes the water ingress!
You can remove the whipers and the plastik there and it's way esay to get to the bollts ... you just have be careful when removing that cuz it can break really esay
Hi thanks a million for this!! Do you have any guidance on reattaching a dislocated sunroof drain tube to the exit nipple? I think mine is decoupled and I can’t find any explanation on how to fix, only remove clogs.
Great video. Thanks a lot. Now I know why my airbag crash sensor passanger side with error code 1222 G-180 does not work due to water leak coming in from that side.
Nice video. Very well narrated. Not sure I’d do the silicone thing as it would make future issues harder to deal with but maybe an extra space under that seal you removed, so that it fits tighter. And regular removal of the debris in those trouble spots can’t be overemphasized. Thanks for your help!
nice video, what do you think is the best way to dry out the sponge that lays underneath the carpet? I was running a cable for my subwoofer and noticed its soaked with water...
Your video is pretty good, tx a lot.. so I also get water on the back seat, passenger's side, .. I got to the pollen filter (which I def need to change) and touched the foam under the encasement, the foam that goes around the gasket, and that seems to be dry so I am not 100% sure my leak is there... if the water is leaking FROM there... would the fan and socket get wet or show signs of being wet? Thank you again for your amazing video.
If its leaking from the pollen filter, you would have water in the the front passenger footwell. You can check your door rubber seal and the rubber boot that covers the wires by the door hinges.
@@CraftyWorkshopBuilds thank you for your answer, .. so, is there a hose that goes from the sunroof to the back door rubber/boot rubber area? If so I will take it off and look for .. a jammed hose? Thank you again for sharing knowledge
The drain from the sunroof goes towards the front. You could roll back the carpet in the back, closed the doors, and have someone use a garden hose to spray the car, while you try to figures out how the water is entering the cabin.
I drive a Passat B5.5 2003 I had no problems with it, it is comfortable and spacious, goes well, accelerates a good engine, consumes no oil, and is a small consumer in terms of fuel. But one day it was raining at night and the next day I noticed water, ie a smaller bar in the back seat behind the front passenger, I thought that it might not be from a window that might not have been closed properly so I cleaned it and did not even pay attention to it .. it started raining again all the windows this time and I closed this time and the next day I had something to see and the water a large amount in the back behind the passenger. I took it off with a sponge and cleaned the cloths and checked the drainage pipes on the car under the battery were visibly clogged, but I cleaned them well both holes and also replaced the climate filter which was quite bad, that is, cabins but water and further away from somewhere so i wonder where the more water can enter is not clear to me? Do you have any explanation and if you can help me with this? Thanks in advance. Greeting!
Remove the carpet in the front passenger side, check to make sure there is no sign of water, moisture or mold. If everything looks ok below the front carpet, then check the other possible places it could be leaking from. It could be leaking from the sunroof, the door rubber seal or the rubber grommet by the door hinges. Remove the carpet behind the front passenger seat. Get a garden hose and spray water on the car to replicate rain falling. Make sure the two passenger side doors are closed while you spray water on the car. while the rear passenger side carpet is pulled back search from the inside to see if you see water seeping in from anywhere. It would be good to have someone else spray the car with the water hose while you search the inside.
@@CraftyWorkshopBuilds hey buddy thank you so much for helping me with this. I found where the water was flowing, and I found with my father that when we removed all the plastic from the back left door and at the one where the window lift mechanisms and the central lock were attached where it was, so that metal part collapsed, which is what the raw rubber was. and fixed it failed so now you take that rubber and put the silicone in and replace it and try on the garden hose and nowhere does the water go or no more passes ... greeting friends.
When I got my B5.5 there was water around the TCM box. After that now I have water behind the driver seat. Realistically the passenger foot well behind the driver and only there. Wondering if that’s because of the pollen filter or is it because of the drains under the battery ?
@@CraftyWorkshopBuilds Will check them, as I don’t think it’s the drainages from the sun frog as my coworker that helped me get the car back and running checked them and they were ok
LIKE YOUR STUFF -- YOUR A NATURAL.-- HELP ME OUT. NEED SOME HELP.... cleaning the exterior firewall I came on a part just behind the ECU unit - it appears a mouse had eaten through some wires that had been attached to a sensor or relay to something. it is blocked by ECU and panel under the wiper arms. need to remove @t get to it. BUT can't figure what it is. what it runs . - two problems I have is --- washer sprayer doesn't work and passenger side mirror won't fold in. WHAT THE HELL IS THIS THING. ANY HELP -- this is a 2002 v-6 glx passat - auto trans - 4 motion.
Definitely check to make sure that no wires are exposed and touching each other. If there is, definitely fix that first. The motor on the mirror and the washer sprayer could be bad. However, check all the fuses first.
I got a 2005 passat 1.8 ran low on oil till the light came on. It lost power and had like a miss. They changed the oil and filter no water in oil but it has a rattle or maby a knock. What do I need to do. I'm thinking of buying it.
Misfire could mean the spark plugs need to be replaced, or possibly a bad coilpack. Check those. You can also do a Compression test, on all four cylinders to make sure they are holding compression. If its making a knock sound after the car went low on oil, that noise could be rod knock, possibly spun a rod bearing. Try to have someone listen to the knock to identify if its rod knock if you are not able to identify it yourself.
Please please help. I have a 2009 Passat and I live in India. The driver’s side has been switched to the right and I have a massive leak in the driver’s footwell as well as the seat behind. I have been stuck in a place away from home and hadn’t used the car for 4 days and allowed it to sit in the rain. When I went to check on it I noticed the leak which was a half inch deep puddle at least. The rest of the car is completely dry. I checked to see if the engine started and it did, then I left it as it was because I was having a personal crisis. I checked on it today and the engine isn’t starting, none of the electricals are working and my key won’t even lock or unlock the car. The puddle was at least an inch deep today and I did my best to drain the water from the footwells. What do I do? The mechanic I contacted will only be able to collect my car in 5 days. I’m wondering if its state will deteriorate by then and if there’s anything I can do :(
Hey, I'll state my opinion below. Not starting problem: Check all the fuses in the fuse box make sure they are all good. Test the battery and make sure it's not dead. Water leak problem: partially pull back the carpet and leave a fan running to dry the carpet, mold will grow if its now dry properly. Here are some possible places where the water might be entering: sunroof, door rubber seals, water drain channels.
Crafty Workshop Builds thank you so much for your help! The battery was dead and the water leaked in because the car was parked on a slight hill and was tilted towards the right, so water seeped in through some drain. Getting it cleaned and sorted now, thank you!
Why silicone? Why not simply order a new gasket from dealer? If silicone is the fix then why is there not silicone used at the manufacture phase? Also, I’ve seen another video posted which suggests this leak could cause fogging on the windshield whenever it rains on cold (below 55 Degrees F days/nights)
I used silicone because it was the best thing that I know of, that could fix the leak. Why would I order and use another foam gasket from the dealer, knowing that the foam gasket is not able to create a proper water seal? The dealer not using a proper water seal, that's a design flaw that I can't answer on. Yes, if there is water or moisture inside the cabin, I will cause the glass to fog and not just only the windshield. All the glasses are prone to fogging depending on the amount of water or moisture that's inside the cabin.
All information and direction on this is pretty on point. I also appreciate the fact that you stated the issue, addressed the issue and concluded with issue resolution without 10 minutes of unnecessary off topic rambling that many other how to videos are guilty of. 10/10 my man, excellent job.

Take the wipers off,then the black plastic shroud ,which is clipped into a slot under the screen,can be removed,making access 100% better

This is the main culprit. The drain under the battery on the Passat and Allroad gets saturated with debris and makes a huge pool there, making water ingress thru the air inlet.
Great step by step instructions! Thanks a bunch. About to get out to the driveway, tear up some carpet, squirt some silicone, run some fans and see if I can get my TCM dry. I’m getting a torque sensor error on my 2005 Passat TDI that I hope is just because things got wet, not because I need a new tranny at 210,000 miles.
Thanks for watching! Good luck with your repair. Yea, it sucks when water leaks inside the car, it can cause all kinda problems.
@@CraftyWorkshopBuilds Sucks bIg time. This is my third Passat and the previous two both suffered massive water ingress. This one got to 200,000 miles before it happened. Was my fault. I didn’t clean out the filter area thorough enough after a few years. Should have known better.
Anyway, got the carpets up and the air filter sealed with silicon. TCM was AOK inside but the wiring bundle had been soaking along with the carpets. Have had fans and some small gel dessicants on it for two days now and it’s still crazy damp. Clearing the error code is only a temporary fix, but the car drives just fine so I think I’ve got a good shot at fixing the issue with this dry-out.
HOT TIP: The rear nut on the cabin air filter housing is indeed tough to get at. But after several failed attempts to loosen it, I found that releasing the plastic baffle that attaches to the windshield allowed me to twist the baffle just enough so that I could get a small ratchet back there. Then the big issue was that there was so much dirt in and around the bolt that I could barely get the 10mm socket to seat on the nut. Had to scratch and brush it all out of the area first.
I had water sloshing around in my TCM housing and for a second was really worried - but we swapped in a 5 speed and got rid of the TCM years ago. Fingers crossed that this fixes the water ingress!
@@maceschoolworhy4446 Is that a difficult task to put in the 5-speed manual? I have the 1.8T L4 FWD.
You can remove the whipers and the plastik there and it's way esay to get to the bollts ... you just have be careful when removing that cuz it can break really esay
Hi thanks a million for this!! Do you have any guidance on reattaching a dislocated sunroof drain tube to the exit nipple? I think mine is decoupled and I can’t find any explanation on how to fix, only remove clogs.
I read somewhere to check the splices in the wiring. Would you happen to know the colors? They said it's 3 spliced wires that corrode when wet.
Exact same thing happened to my 2000 VW Passat B5, except the corner by the windshield was rusted out. Had to cut it away and insert a plate.
Awesome! I had the same issue, was stuck in limp mode and was not communicating with OBD2. Thanks!
- thanks, greetings from Belgium
Thanks for watching and shout out to all the viewers from Belgium!
It's not my business, but in my opinion you should replace the cabin filter
Also remove the scuttle panel and make your life sooooo much easier 👍🏻
I wouldn't use silicone, i'd use butyl. If you need to remove the parts again it's easier. Butyl stays better and it heals itself..
this is the best video and you make it nice and clear great job and thank you!
Much respect! I'm happy you got value from this video, thanks for watching.
Thanks for sharing. You should have replaced you filter while you were doing the water leak fix. It looked really dirty!
Thanks for watching! The demonstration was just about fixing the water leak, the filter is easy to replace.
@@CraftyWorkshopBuilds Hopefully no more water leaks for you. I have an '05 Passat. I need to do that on mine
A very good and detailed video.
Much better than others on this importang subject.
Much appreciated!
Can any of these lead to water only in the rear carpet footwell behind the driver and only there
Great video. Thanks a lot. Now I know why my airbag crash sensor passanger side with error code 1222 G-180 does not work due to water leak coming in from that side.
I'm happy you found the issue! thanks for watching.
fantastic video! thank a lot! will fix my B5.5 this summer too!
Super helpful, thank you.
Glad it was helpful!
Thank you bro! You are the best. Helpful and well presented 💯
Much respect, Thanks for watching!
Nice video. Very well narrated. Not sure I’d do the silicone thing as it would make future issues harder to deal with but maybe an extra space under that seal you removed, so that it fits tighter. And regular removal of the debris in those trouble spots can’t be overemphasized.
Thanks for your help!
The recall when I work for Volkswagen we used to dumb dumb which is like black window tar seal it works much better and never dries out
You do have to use some sealant
Very nicely explained thank you 😊
Much respect 🙏
Very nice and helpful video, and a nice calm voice and speak. Thank you! :)
Glad it was helpful! much respect 👍🏽
thanks man! i have my carpet soaked on my Passat Wagon, i'm going to do that this weekend!
Sure, go for it! Thanks for watching.
nice video, what do you think is the best way to dry out the sponge that lays underneath the carpet? I was running a cable for my subwoofer and noticed its soaked with water...
Fold back the carpet, get a fan and let it blow air on the sponge for couple hours.
Great information, thanks 😊
Much respect!
Your video is pretty good, tx a lot.. so I also get water on the back seat, passenger's side, .. I got to the pollen filter (which I def need to change) and touched the foam under the encasement, the foam that goes around the gasket, and that seems to be dry so I am not 100% sure my leak is there... if the water is leaking FROM there... would the fan and socket get wet or show signs of being wet? Thank you again for your amazing video.
If its leaking from the pollen filter, you would have water in the the front passenger footwell. You can check your door rubber seal and the rubber boot that covers the wires by the door hinges.
@@CraftyWorkshopBuilds thank you for your answer, .. so, is there a hose that goes from the sunroof to the back door rubber/boot rubber area? If so I will take it off and look for .. a jammed hose? Thank you again for sharing knowledge
The drain from the sunroof goes towards the front. You could roll back the carpet in the back, closed the doors, and have someone use a garden hose to spray the car, while you try to figures out how the water is entering the cabin.
I drive a Passat B5.5 2003 I had no problems with it, it is comfortable and spacious, goes well, accelerates a good engine, consumes no oil, and is a small consumer in terms of fuel. But one day it was raining at night and the next day I noticed water, ie a smaller bar in the back seat behind the front passenger, I thought that it might not be from a window that might not have been closed properly so I cleaned it and did not even pay attention to it .. it started raining again all the windows this time and I closed this time and the next day I had something to see and the water a large amount in the back behind the passenger. I took it off with a sponge and cleaned the cloths and checked the drainage pipes on the car under the battery were visibly clogged, but I cleaned them well both holes and also replaced the climate filter which was quite bad, that is, cabins but water and further away from somewhere so i wonder where the more water can enter is not clear to me? Do you have any explanation and if you can help me with this? Thanks in advance. Greeting!
Remove the carpet in the front passenger side, check to make sure there is no sign of water, moisture or mold. If everything looks ok below the front carpet, then check the other possible places it could be leaking from. It could be leaking from the sunroof, the door rubber seal or the rubber grommet by the door hinges. Remove the carpet behind the front passenger seat. Get a garden hose and spray water on the car to replicate rain falling. Make sure the two passenger side doors are closed while you spray water on the car. while the rear passenger side carpet is pulled back search from the inside to see if you see water seeping in from anywhere. It would be good to have someone else spray the car with the water hose while you search the inside.
@@CraftyWorkshopBuilds hey buddy thank you so much for helping me with this. I found where the water was flowing, and I found with my father that when we removed all the plastic from the back left door and at the one where the window lift mechanisms and the central lock were attached where it was, so that metal part collapsed, which is what the raw rubber was. and fixed it failed so now you take that rubber and put the silicone in and replace it and try on the garden hose and nowhere does the water go or no more passes ... greeting friends.
@@BOGGY89KV Oh cool! I'm glad you were able to find and fix the leak.
@@BOGGY89KV My car has wet carpet behind passenger side seat in back as well.
So the problem is a rubber grommet in the back passenger door?
Fantastic video, really helpful and perfectly explained. Thanks very much for your help.
Much respect and thanks for watching!
Great how-to. Keep it up
Thanks, will do!
Did the same silicone treatment yesterday and tested it by pouring water on the windshield pulled the carpet up and no water coming in👍🏼
@@funda5135 nice! Glad you were able to fix the leak.
Great video.helped me out a lot.
Happy I was able to help! Thanks for watching.
hello from Slovenia, do you maybe know why the esp light is on, it just turn on and i canot turnit off ... its passat b5.5 year 2004
You'll need to scan the car and see the code.
cheers dude! just the video i needed!
I'm happy you found this video! Thanks for watching.
When I got my B5.5 there was water around the TCM box. After that now I have water behind the driver seat. Realistically the passenger foot well behind the driver and only there. Wondering if that’s because of the pollen filter or is it because of the drains under the battery ?
It could be both, you'll have to check it out to find out.
@@CraftyWorkshopBuilds Will check them, as I don’t think it’s the drainages from the sun frog as my coworker that helped me get the car back and running checked them and they were ok
Thanks!
Thanks for watching!
LIKE YOUR STUFF -- YOUR A NATURAL.-- HELP ME OUT. NEED SOME HELP.... cleaning the exterior firewall I came on a part just behind the ECU unit - it appears a mouse had eaten through some wires that had been attached to a sensor or relay to something. it is blocked by ECU and panel under the wiper arms. need to remove @t get to it. BUT can't figure what it is. what it runs . - two problems I have is --- washer sprayer doesn't work and passenger side mirror won't fold in. WHAT THE HELL IS THIS THING. ANY HELP -- this is a 2002 v-6 glx passat - auto trans - 4 motion.
Definitely check to make sure that no wires are exposed and touching each other. If there is, definitely fix that first. The motor on the mirror and the washer sprayer could be bad. However, check all the fuses first.
What is the piece that you removed first
Which piece where?
This was great help. Thanks a lot!
I'm happy you found this helpful, thanks for watching!
Great video btw :-)
Thank you!
Cheers mate, great video with All the detail I need to fix this issue back in the UK. Many thanks, great channel & keep content coming 👌👍👏👏👏
Happy I was able to help! Thanks for watching. Yes, more content on the way.
Thanks bud. Big help
Sure, thing. I'm happy this was helpful to you.
Don't use silicon but some automotive glue such as Sikaflex product.
Silicone will cause a rust issue.
Old-fashioned dum-dum is what Volkswagen used to have us do
I got a 2005 passat 1.8 ran low on oil till the light came on. It lost power and had like a miss. They changed the oil and filter no water in oil but it has a rattle or maby a knock. What do I need to do. I'm thinking of buying it.
Misfire could mean the spark plugs need to be replaced, or possibly a bad coilpack. Check those. You can also do a Compression test, on all four cylinders to make sure they are holding compression. If its making a knock sound after the car went low on oil, that noise could be rod knock, possibly spun a rod bearing. Try to have someone listen to the knock to identify if its rod knock if you are not able to identify it yourself.
Dude, sell those saws and get yourself a vacuum cleaner.
Nice job on the video. How is the interior smell after all that silicone?
The silicone don't have any odor once it's dried. No issues with interior smell.
I have the same problem (VW passat b5 FL, 2001) and I will do as you showed, maybe it will solve the problem
Yes, sure. It's a common issue.
Remove battery and clean two pipes for water drain, no silicon needed
Forget the silicone and use Butyl tape 👍🏻
No mess and a far superior seal 👍🏻
Thank me later 😁
Im going to try in my audi a4 b7 cabtiolet.
Go for it, pretty much the same platform.
I have a lot water from left side back..where that comes from?
Check the sunroof and door rubber seals.
Please please help. I have a 2009 Passat and I live in India. The driver’s side has been switched to the right and I have a massive leak in the driver’s footwell as well as the seat behind. I have been stuck in a place away from home and hadn’t used the car for 4 days and allowed it to sit in the rain. When I went to check on it I noticed the leak which was a half inch deep puddle at least. The rest of the car is completely dry. I checked to see if the engine started and it did, then I left it as it was because I was having a personal crisis. I checked on it today and the engine isn’t starting, none of the electricals are working and my key won’t even lock or unlock the car. The puddle was at least an inch deep today and I did my best to drain the water from the footwells. What do I do? The mechanic I contacted will only be able to collect my car in 5 days. I’m wondering if its state will deteriorate by then and if there’s anything I can do :(
Hey, I'll state my opinion below.
Not starting problem: Check all the fuses in the fuse box make sure they are all good. Test the battery and make sure it's not dead.
Water leak problem: partially pull back the carpet and leave a fan running to dry the carpet, mold will grow if its now dry properly.
Here are some possible places where the water might be entering: sunroof, door rubber seals, water drain channels.
Crafty Workshop Builds thank you so much for your help!
The battery was dead and the water leaked in because the car was parked on a slight hill and was tilted towards the right, so water seeped in through some drain.
Getting it cleaned and sorted now, thank you!
Okay, cool. I'm happy you found the issue.
Why silicone? Why not simply order a new gasket from dealer? If silicone is the fix then why is there not silicone used at the manufacture phase?
Also, I’ve seen another video posted which suggests this leak could cause fogging on the windshield whenever it rains on cold (below 55 Degrees F days/nights)
I used silicone because it was the best thing that I know of, that could fix the leak. Why would I order and use another foam gasket from the dealer, knowing that the foam gasket is not able to create a proper water seal? The dealer not using a proper water seal, that's a design flaw that I can't answer on.
Yes, if there is water or moisture inside the cabin, I will cause the glass to fog and not just only the windshield. All the glasses are prone to fogging depending on the amount of water or moisture that's inside the cabin.
Why didn't you just remove the wipers and plastic valance, would of made your life much easier
Great video,man;
very poorly made car!! and then water leaks onto the electronics!! *avoid*
Yes, once water leaks inside it damages the computers below the carpet.
You can thank Audi for this fault as it affects Audi 4s and 6s, they're great cars otherwise
I have the same problem in .y car
Now I know how to fix it
Thanks brother 👍
No problem 👍
