same problem. trying to figure it out now. most likely the blower motor

I tried to repair (or someone who can repair) that blower motor and it appeared to be non-repairable closed unit, I mean the motor. Of course nothing is impossible :) But it would more economically reasonable to get working unit from scrapyard or get new one. By the way, do you change pollen filter regularly? Because it can affect motor if it's too clogged up.

I had a problem with the flood as well. I have couple videos about this problem. This one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gE3pxrEK8DA.html and this one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gQCSuO3sAXI.html

WheelsAndMotors Hi! First, thanks for your prompt reply! I reviewed these 2 videos and they gave me useful insight into the issue at hand. I am still unable to pinpoint the exact root cause for the leak into the interior compartment. I've already cleared the drainage canals and water drains away from the blower box area. However, I discovered that the ECU box has a crack at the bottom (due to LPG installation) and it is possible that water gets inside and from there into the interior. I will replace the cracked box tomorrow and hopefully the issue will disappear. For the record, I fixed the A/C and heating system. I tested if the blower can rotate by hand and then applied electrical current directly from the battery to ensure it can spin. The issue was due to a non-factory faulty wire which caused short circuit of the electrical system. Anyway, your video tutorial was very useful for which you have my thanks!

Try to look for Elsawin on eBay.

Siete i benvenuti :)

Sorry Jason, I didn't get to details, just replaced the whole thing, therefore I can't give good advice. In my experience control module or whole unit don't seem to be different in price that much..

Don't know what exactly causing that noise, but if you have a time, probably would be worth to take it out, see whats going on - bearings or just need for some cleaning..

All heated bits that you mentioned are heated by electricity, not coolant or hot air, so I think you should look for electrical fault solution.. start with fuses. Unfortunately, I don't have that car anymore, but you can have a look in owners manual (normally kept in glovebox), they have list of fuses at the end of that book.

Thanks 👍 I don't have that car anymore, but it will be helpful for others.

BessieMorrison Have a search in internet. There can be many sources. I have seen one guy selling ElsaWin on eBay..

BessieMorrison I'm trying to create it on my website, but it's still long way to go - we need to get more people involved.

If there is, I don't know about it, sorry.

Sorry Kevin, I don't have that car for over 5 years, I don't remember much. I hope you'll get it sorted.

When I replaced my motor (bought another one from scrapyard for 60-70 pounds), I also tried to fix the one that's faulty. Brushes were worn out and one of them was even hanging awkwardly on a spring. But I had a problem with getting to those brushes. The motor seemed to be closed unit and there were no obvious ways how to disassemble it. I'm not professional, so I took it to some electricians - they said that it's not meant to be taken apart and it's cheaper to buy another one. I don't know - maybe they were also not very professional. If you know how to do it - you can make a good RU-vid video out of it :)

oh wow it was so easy to take it apart next time i will record that thank you :)

donde la compraste??

Part number can be 4F0820521A, but I can't guarantee, sorry. When I search eBay for this number - some listings come up with motor and control unit, some with just a control unit, .. Audi dealerships don't like to give out part numbers. I would look for 'blower motor Audi A6 2005-2011', if I'm not mistaken they are all the same for all engines of C6 chassis. When my motor died, it also didn't die suddenly - brushes were wearing out - if I 'whacked' it started again :) My advice would be - if you are getting in there - replace it all. By the way, when I replaced my motor, I took it apart and tried to find someone, to fix brushes - it appeared to be sealed unit - non-fixable. Here's post about blower motor at my website: www.wheelsandmotors.com/show_solution.php?id=16

You're very welcome Kasey 😊👍

Steve Bergholtz If AC is not cooling and you can't turn ECON off, more likely it just needs re-gasing, if ECON goes off - could be compressor problem. Regarding not blowing at all - either blower motor died, or before check the fuse (have a look in drivers manual), I don't have that anymore, so I couldn't point you...

Hi, if it's not blowing, I recon the problem is with blower motor again or its controller.. Because blower motor is the thing responsible for blowing :) I hope you have a bit of warranty for that bought one.

What does a scanner say?

I will make a video about it, but I don't know when. Meanwhile I believe this link may help you: wheelsandmotors.com/show_thread.php?id=71

+lnerdrum You can access pollen filter from behind the glove box. So ventilation system does stretch that far :) Not sure about Allroads, I thought they are all the same.. Please, let me know, if I'm wrong. The blower is pretty universal - if I'm not mistaken, they put them even into Lamborghini's :))

Just done Allroad 4.2 V8 , locaton is the same as in this video but have more wires around so it is little harder to remove.

That must be fun car to drive 😎

I don't know much about A8, but as far I know - it must be in the same place (chamber).

Not 100% sure, but I think that compartment is more or less the same for all range of these models.

There is only one blower motor for blowing air inside cabin. There's also condenser (radiator) fan that helps cool down radiators (coolant and AC).

WheelsAndMotors thanks boss

Yes in 2005 they had a bad design for oil pump (chain driven ) then I think in 2006 they changed to gear driven to solve the problem. As for anything else - see my other videos I tried to cover the problems I had.

If I'm not mistaken they use same blowers even for Lamborghini :))) When I tried to search internet with the part number, I had search results as blower fan Lamborghini. The part number can be 4F0820521A, but I can't guarantee, sorry. When I search eBay for this number - some listings come up with motor and control unit, some with just a control unit, .. Audi dealerships don't like to give out part numbers. You can also try to ring TPS - trade part specialists, they probably won't give part number either, but at least maybe they can confirm that it's the same motor for whole range of A6. Here's the link: www.thetradepartsspecialists.co.uk/contact.php

thanks boss for the information

+NastyMosquito For some reason RU-vid has put your comment into "spam" - only found it now. Those pistons need a really good clean, or maybe control valves are completely dead. Here's a link to my website about how we clean that: www.wheelsandmotors.com/show_solution.php?id=4

+WheelsAndMotors Thanks buddy.Cleaning the valves did not help....Iam just wondering if you had very hot air on ECON mode, without A/C on....?

+NastyMosquito I had very hot air no matter AC (Econ) was on or off. I'm pretty sure it's the valves problem - if cleaning doesn't help - maybe it's a faulty unit (control valves). Of course there could be tiny chance of faulty climate control buttons, but, IMAO - more likely bad valves.

+WheelsAndMotors Thanks so much for your help :) Last question.If I put my fingers on the unit and other person will switch ventilation modes on the panel, will I sense them working ...? Btw-Happy New Year :)

+NastyMosquito That unit is responsible for temperature control - coolant flow through heater. For ventilation modes - diversion of the air-flow there's something else. Happy New Year :)

Not sure what you mean by relay, if it's compressor regulating valve - it's on the side of compressor.. I'm not that good with AC components - only replaced compressor couple times.

I had problem with water getting into the cabin, but that was rain water, I made couple videos about that. This one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gE3pxrEK8DA.html and this one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gQCSuO3sAXI.html If it's a coolant that's leaking - I can't help, sorry, I don't even have that car anymore.

Спасибо :)

+David Babs Could be a unit that's responsible for deflecting air flow in different areas. Unfortunately, I don't have experience with that yet. I would recommend to find specialist with VAG-COM (VCDS) to scan it and find where the problem is.

Ops.. Never had problem with wipers, despite that car has done 409.000 miles eventually.. don't even know what to suggest. I know that wipers won't go on, when bonnet is open.. Could you damage some wire while doing blower motor? Just had a look in manual, wiper motor is quite easy to get to. You still need to remove that scuttle panel trim. For some reason my manual shows only left hand drive car, where unit is located above screen wash filling cup. For right hand drive cars it's on the other side. Held by 3 bolts.. Never done it myself, and that car was gone about 3 years ago, so apart from "check for damage" can't help much, sorry :(

It also says that wiper motor control unit is integrated in wiper motor

Hi Julio, most likely it should solve your problem. Of course, you can find someone with some clever scanner, to diagnose that the fault is exactly in blower motor to know for sure.. I think that if if the air is not blowing 99% it would be blower motor fault.

WheelsAndMotors thanks, will try next week;)

+JohnnyIvan5 yes I had this problem! It's a common fault. Here's the link to solution: www.wheelsandmotors.com/show_solution.php?id=4

+WheelsAndMotors Ohh!!! Awesome! thank you!!!!!! Your Videos is very helpful!! :)))

Hello, were you able to fix your blower?

Thanks for your comment Andy! I think you're the first one to mention it. I don't remember much from the time I made this video, I don't even have that car anymore. Maybe it was some screw that my car didn't have? I took it out somehow without much resistance...

Blower motor compartment should be the same as my 2.0tdi.

Is it just screen black or buttons on MMI also without light? I mean inside light on MMI control buttons.

WheelsAndMotors none of the buttons light up either. Ive tried to do the reset by holding those 3 buttons but nothing happens

It's had to say, could be lost or broken contact somewhere. Ideally would be to scan it with VAG-COM. I have a video, where I disassemble it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SH1PrInREi4.html

I meant "haRd to say"...

Okay cool thank you

Sorry, but I don't have experience with going into details... I just know how to replace whole thing. I know that resistor is sold separately, but considering that brushes on that motor wear out too - so with a lot of miles that I do, I just stick new one in. Sorry that I can't help..

@@wawayltd No problem. thanks for replying anyways. I got a friend that will help me with messuring, so i hope to find the fault. but how did you notice your fan was not working. Bacause mine stopped working and kicked in a few times at random for a few sec. no Bad noices or anything. just dead now no air. hoping to not have to replace both because of price. Car only has 140k (kilometres). so its a little wierd to me.

@@xBooMzHeadShotx I had few VAG cars where blower motor died. Sometimes they make noise for a while before they go, sometimes they stop out of nothing, then go, then stop. I think 140k is about time for blower to die. Think about it - it's an electric motor that constantly working, and it has brushes. Whole unit is not that expensive actually. I don't have that car for about 5 years, I drive Sharan now, which is still VAG. And just yesterday I bought spare blower for £80 on eBay. You can have a look in Autodoc or Euro Car Parts, or GSF. Not sure which country you live in. Main dealers and TPS charge ridiculous price for it - with this unit don't see reason to pay that, it's just a stupid ventilator motor. By the way in my car, because it's a 7-seater, I have 2 motors - one at the front and one at the back.

@@xBooMzHeadShotx Did you change your blower? Or just the resistor? My car is doing the same than yours, sometimes the air blows and sometimes it doesn't. Thanks

@@eduardoangeles4412 In my case it ended up beeing the Ac senor on the radiator. had to ramove front bumper and replace sensor. you could put 12v on the fan and se if it spinns, and messure Ressistorbox volt in is 12v.

Sorry Ronny, that was while ago and I don't have that car anymore. As I remember it was quite intuitive to put it right. Not sure what it does though..

If your blower motor is not working, not blowing air, then you have found the right video how to replace it.. Unless there is some blown fuse (check owners manual for fuse diagrams, because I don't have that car anymore).

Fuses checked. Ok thanks, will attempt the fitting! Thank you very much for your help!

You're welcome :) Hope it helps..

It was going loud, uneven, and eventually stopped.

Does it make any noise? Maybe blocked filter?

@@wawayltd i found the problem .... when i removed the ac pressure sensor it worked but no ac of course... i will try to change that one and see ...

Viņi to dara pirms saluzties. Es domāju, ka tas ir jāmaina.

+Mark Robinson I have a feeling that we are having same conversation here and at my website :) Let's keep it simple..

Is it blowing at least little bit? If it does - try to change pollen filter.

Will do thank you for reply

Did you replace blower together with that control unit?

@@wawayltd hi thanks to reply me... Not I didn't... I just replaced the blower's motor together.

@@yuniordominguez7810 I don't know, then it could be either issue with wiring, or new blower is no good.. Do you have warranty?

First, I would check pressure in AC system...

WheelsAndMotors ok compressor seem not to be on no ac just fan

If the pressure in AC system is no good, then compressor won't start. I had same problem. In those garages, where they re-charge AC, they can also check if there are any leaks in the system. If it's just a pressure, then re-charge is easy solution. If ECON can go on and off, but compressor still doesn't start, then likely there's a problem with compressor.

WheelsAndMotors Alright thanks I don't have those ac gauges to check pressure . Can try adding freon with a can from auto parts

WheelsAndMotors to see if compressor kicks on

Ceci est 2005 Audi A6 (c6, 4f) et il a 2.0tdi moteur.

Grateful for your videos, they're invaluable. Please always include in the titles what model year you're working on. Thx!!

Now I do in my latest videos :)

No. I'm in Bristol 😉

Ok will try and do

@@bernardjohnston819 Before you try - make sure your pollen (cabin) filter is changed, maybe there's no need for new blower. Filter needs to be changed once in a while anyway..

Where is pollen filter ?

@@bernardjohnston819 I have a video about it, here's the link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QM18XXWpZPI.html
