FIXING MY AUDI Q7 FOR FREE!! AUDI WANTED £10,000!!! 

Never install o-rings dry, always use oil or assembly fluid to prevent drying out and leaking.

50 years ago a good mechanic would have happily diagnosed the issue correctly and charged you a few hours labour to do what you just did. Today, being a mechanic generally means (obviously not all) learning how to use a diagnostic machine to tell you what parts you need to order and then just swap. Far too much of a throw-away society today IMO. Good job well don pal !!

Amazing fix! The stealerships will always rob you blind when it comes to their “oh you want a simple circle of rubber? Oh wait that’s £10k! Honestly you’re right about that being theft.

My wife's Q7 does this over the course of a week ... you've cheered me right up! NO way would I drop £10k on a £5k 2008 car but she loves it ... now I can get brownie points for the price of a spritz bottle and an afternoon of my time.

Great result. O rings are easily found in seal and gasket suppliers. Also a light smear of grease can help the o ring work

Fair Play Dean just shows you what you can save in this throw away society. Proper Mechanic great video keep them coming

As I don't have my own workshop / garage you just explained the precise reason I don't own an Audi. The sales team behave like they're doing you a favour and the cost of parts (beyond the basket they used for fleet sales quotes) just leaves me incredulous... Nice Job. I'm sure if you had the time, you could have identified and sourced that 'O' ring. Great channel, thanks for posting.

This is incredible! So many issues with cars at actually due to cheap small parts yet most garages replace whole units/kits because they don’t know what the problem is.

As a gas emergency engineer that finds and fixes gas leaks on a daily basis I found this video hugely satisfying…. Fingers crossed that’s the end of the matter! She will make a good car to keep Dean. Nice work bud.

Great fix Dean, I think I was like a few others ducking when you drove the Q7 in the workshop, it's nice when something goes right for you 👍👍😷😷

Good work Dean. Nice to see someone else actually trying to fix things rather than just replace. I literally save thousands every year by doing this.

Hi Dean, O rings of the size you have on your air suspension are readily on line, or local engineering suppliers. O rings can take a set so are not as effective when reusing, and yes always use a suitable grease to help with resealing as per Snoppy. Nice fix as usual.

Any engineering supplies place could get those new O rings Dean, worth smearing them with silicon grease upon re assembly, great fix though 👍 Imagine how many Q7's are going to the scrapman once these bags start leaking but folks not realising it's such an easy fix

Don’t you get a great sense of satisfaction when you fix something for free and it works. Brilliant job.

Alloy oxidisation just pushing it apart! Happens on lots of stuff. Abs sensors on peugeot spring to mind. Remove, clean, thin layer of grease to stop or slow it down in future and refit! Nice work, mate! I'll remember this for the future.

first sponsor ever to interest me for real. i'd look into it if i could buy locally, but i'm not going to go as far as importing it. but yeah, nice product

From Germany. Bought my daughter a 15 year old Audi A2. Spent countless hours saving limitless 1000's of Euros by DIY and not going to AUDI. So your videos were priceless for me. Great work. Keep sending. Regards.

The best tip given to me by an old spanner regarding any rubber seals is to soak them in transmission oil over night & it reconstitutes the rubber to make a better seal👍

These are the best videos Dean, just love your approach to fixing stuff. 👍🏻

Changed rear air bellows on a 5 series touring, good quality parts off Ebay for £80 a pair. Work took just three hours, fiddly but relatively straightforward. BMW wanted £2k for the same job! Eighteen months on and no issues....Lesson learnt.

Now that’s what I call a fantastic save and well executed diagnosis and amazing that those ring seals still worked, I bet Audi just love ❤️ you Dean 😂👍🏻, good video mate.

Great fix Dean, I always use silicone grease to help prolong the life of o rings.. Wishing you well 👍

I have been to a bearing & seal suppliers and matched o-ring sizes in the past and repaired things for next to nothing. They are only standard sizes in round seals it’s only ones with curves and turns that you wouldn’t get from a suppliers

What a superb vid, love the fact you found a solution, this is so helpful for any q7 owner, I had same issue with with Mercedes R class . Brilliant free fix

Top job. I was recently told by Dealership that my EGR valve needed replacing. I studied about it, the system and took it off, dismantled it, cleaned the soot off the part and reassembled.. Car milage back to normal and saved me the estimated 550euros for a new one which i did not need. These “ stealerships” are criminal money making machines.. shocking.. great job Mister!!!!

Some lads are just born great engineers. Really enjoy watching how easy you make it all look, pretty sure I would struggle with most of what you do.

I love fixes like this. About 11 years ago I owned a Volvo S80 T6. Dashboard messages about brake and steering faults, and to stop immediately. A bit of research told me it was likely to be an ABS electronic module under the bonnet, for which my Volvo dealer would relieve me of something like £1400+VAT. Further research revealed it was likely a cracked/dry solder joint on the power inlet to the module. Half an hour to remove it. Another 20 minutes to dab each solder joint. Half an hour to refit it. Problem solved. Only cost was £15 for a set of sockets for the Torx head bolts that I needed to undo.

Dean you will not be a favourite down at the Audi centre but will however be a star with many Q7 owners. You definitely have my vote and exemplify the difference between a mechanic and a "fitter".

Great fix, Dean. I would have done the same as you did. (always looking for the cheap & cheerful alternative) 😊. Great result. Replacement parts in stock, for similar project. With not a so easy fix. 👍👍

So satisfying when a job works.

A great video - thanks for sharing. My son has just bought one of these & now has the same issues. No guesses on who is going to fix it for him (Dad) me & I will definitely be following your repair procedures. Great video & now hooked on your channel 😂

Wow, what a result for free! I wonder how many Q7's have been written off because of the fear about how much this issue is to fix? Brilliant video, looking forward to the next video on the Q7.

I've repaired leaking o'rings in a similar way to you on other things in the past, the only difference is when refitting the o'ring, I've coated it with silicon greece. Great vid.

The last few words you spoke are absolutely frightening. I love Audi's and have considered getting one as I am informed they rust less than many other makes, but this is absolutely frightening for many owners. Great work, now you should start your own workshop repairing Audi vehicles and probably make a fortune. Excellent video and keep them coming!

Absolutely awesome video mate! Covered everything related to the complicated Q7 suspension including cost of new parts and how to save £££££ 👌👌👌

I am looking forward to seeing the Q7 fixed ! Great fix on the car. This must inspire Q7 owners to also fix the air suspension them selves. No money for the stealership, daylight robbery ! I have stopped calling the Audi stealer, better for my heart and blood pressure. Prices are absolutely criminal. Love your videos. Greetings from the Netherlands.

Excessive Cranking Cold: my DERV used to crank 5 seconds + cold. An 85mph run (2500rpm) for 100miles fixed it. Now starts immediately as it should. Uncovered other faults too, (failing Water Pump Bearings and DMF), well worthwhile

Well done Dean. Very satisfying fix and for nought! Personally I would be inclined to take the fronts off and give them a good clean too.

Great repair ..we live in a throwaway society where main dealer so called mechanics just replace parts until the issue is fixed..unlike years ago when we used to fault find diagnose and repair items..they charge Thousands for a repair that costs pennies but they don’t care those glass showrooms need to be paid for…

Really enjoying the series on this mate great videos keep them coming. Handy aswell after just buying one myself. Hopefully you end up keeping it and using it for your job instead of the pick up 👍🏼

Very well made video..not a boring segment at all.. and a great job on the car 👍🏻👍🏻👍🏻

You can make or get made your own O rings. You can buy O ring kits online. If the existing one isn't compromised you can soak it in power steering fluid and it will swell back to its original shape. When refitting make sure it is lightly coated with silicone grease.

Great fix! Awesome savings. Hope to see more of the q7 soon! I think there is some moisture in the compressor, maybe the dry filter is too old.

Thank you for the videos . Very helpful and can save some money. I'm going to get the Q7 3.0 TDI around weeks time. Hopefully I manage to get to know the car better.

Use the grease used for swimming pool orings and it will make it seal so good

I watch a lot of car guys and I love how you explain things and explain what research you need to do and it’s good Bevause I’m starting mechanics it’s really a passsion but I have no knowledge on it what do ever tbh just went back to college I wish I did it younger I like it when I see people genuine like you leavening new things all the time

Great diagnosis and repair 👍 but, as others have commented, a helping of Instant Gasket or similar would compensate for any reduction/distortion in the shape of the ring's cross-section and any loss of softness/flexibility due to long term pressure and aging.

I can’t believe that they had a quote for 10k and you’ve just had to clean up the O rings for free. What a fix

They sell a kit to make your own o rings. Comes with several different diameters of "cord" which you measure, cut, and glue to make any size o ring. It's used by heavy equipment mechanics repairing in the field. It's a bit pricey at around $250 roughly I believe. I haven't purchased the kit myself but mechanics swear by it. Just a thought for you to consider. Keep up the great videos.

Proper engineering with a correct diagnosis and repair well done👌👌

Oxidation problems causing the problems! Brilliant results mt good video

Yet again really well designed, great work mate & you saved a shed load of money, Rj in Oz

Loved watching the revival of this q7, wish I got a good deal as you did!

Your video skills are getting better and better, great video, so interesting!

Cheap fix👍. I've got an O ring kit so I can make any size. All you do is cut to length the size of O ring you need and glue the ends together, I use this on hydraulics so pneumatic systems are no problem for pressure.

Haunted with this suspension issue and pricey repairs. Thanks for this great videos - I may change my mind to keep my 2008 Q7.

wow what a result well done Dean,,have a great week and see you in the next one,,👌👌✌

That's really good investigation and work there. I may be wrong, my thought seal would get some water on it and it would sit on top. Once the water on top has frozen, it would corrode the top of the seal cause it to offset the rubber allowing air to escape. Anything you could add on the top of the strut to stop the water from gathering and or freezing? 🤔

If I was to do this I would treat the rubber with a hydrater to restore the elasticity of the rubber to just help it even more. Fantastic work as always though and just shows you can save so much money by just being a bit of investigation instead of firing parts at it

Yes totally agree with the silicone grease on o rings also it will help with the alloy corrosion which is what caused the air leak.

Well done dean you saved yourself a fortune mate best thing you done diagnose the problem then fix if possible and then tap yourself on the back for job well done good content dean 👍😆

Brilliant, like the mechanical fix side rather than replacing bit or modules cos some unserviceable component has failed. Well done.

Please rebuild the air suspension pump. For £50 or so for a full rebuild kit and new drying balls it will make sure it survives much longer.

Great video and a free fix, it's crazy the cost of replacement parts and no kits available

I hope as many people as possible see this, great work Dean and great video keep the content coming

Superb! Had this madness with a Merc E350 W211 - it's almost a write off when the air susp dies...

I´m about to do the the exact same thing next tuesday. Hope it will fix the leak and new bags will not be necessary ;) Thank you for this video!

TB6000 is actually an useful tool, I use it also to restore the old battery like desulfation, not always work but it renews 2 batteries already, for my car and motorcycle

What a result. Well done dean.

I'm a retired Design Engineer. You can get ANY size O ring you desire if you approach the suppliers. They are easy to measure and you could also upgrade from a basic Nitrile type ring if you wanted to. I'd also add that the aluminium corrosion has migrated causing the leak in the first place. Some O ring lubricant could mitigate the same problem from reappearing....🤔🤔😏😏😏😏😀🇬🇧

Happy days deano! £1000 and no money to fix. Can't get better then that. Enjoyed this video m8. Good job 👏🏻 👍

Great video again mate. In the future if you need any O rings you can buy O ring cord very cheaply in loads of different sizes. you simply cut it to the length of the old one and use a drop of superglue to join the ends to make it a ring. you can build up a stock of various standard sizes for not much money, saves a lot of headache some times.

Woot woot. Free the best sort of fix!! Bet you are more than well chuffed!

Would have made sense to get some new o rings from a hydraulic shop 👍

Great video. The main dealers/manufacturers do not cover themselves in glory. Currently buying some Mazda parts - all plastic bits around the bumpers and the front panel - a complete rip-off but no pattern parts for this jigsaw like structure.

Fantastic fix 👍👍👍 typical Audi would not even sell replacement seal kit, rather charge you 14k. Never take my car to the dealer.

Great fix, we use vaseline on o-rings if we re use, makes them swell slightly

Your a bloody good mechanic 👍

Great to see a good analysis, well done. Good buy✅✅👍👍👍👍👍👍

Well done ! Great to see a wonderful car being saved rather than being scrapped due to the high prices quoted by Main dealer to repair car. Congratulations

Genius. You are the English Car Wizard! Todays top vid on yt!

That O ring can failure du to the corrosion. Look at the surface! The corrosion goes over the ring and thus the air escapes over, and because of the pressure, cuts the ring. Clean the surface from corrosion, new ring, and use something to protect the metal.

Got to love the £ free fix’s. Well done 👏🏽

Great work. Nice when things can be repaired. 👏💪

Excellent find, were you not tempted to clean up the front as precaution, or use silicon grease on the o ring?

Had a few Audi's in my days and any time I had to go into a dealers for some parts I always took in a chair, they really do take the utter piss.

great repair, I just had one of my suspensions done by an audi dealer in Prtugal. Did cost me 800 euro for one new suspension. Now understand this was cheap (repair was no option - it was really destroyed). 👍

Red rubber grease is good for reviving dry o rings and seals etc

It looked like the powdery corrosion you get on aluminium was disrupting the seal. Great cheap fix.

I've seen this same repair on another Q7 on RU-vid, I would have used some silicone grease on those O rings, but great work. Can't imagine any dealer doing that it would be unit only!

100k by the end of the year👍 keep up the great content

Chuffed for you dude. Well done. Great work.

Well done. All your effort deserves some good luck 🤞🍀

You forget to put some silicone grease on the ring before reinstalling. O Rings work by deforming into the grooves when pressure is applied, the grease helps the ring move about and find it's happy place in the housing. Not a lot is needed, just a rub over on the ring before fitting.

Dean, next time use some vacuum grease on the O ring as it will prevent the situation from occurring again.

Sorry Dean heavy night last night my respect to you didn't read your post properly excellent video today keep them coming 👍

Great fix!! You're quite right, that's rip off pricing, quick polish and a new o ring from the local seal/bearing store and you're sorted.

had a q7 with air suspension problems and i change the air suspension for arnott coil over struts and it works perfectly

Fun fact! I found that o-ring in my swimming pool filter pump o-ring compartment in my work truck! On top of cleaning and lightly sanding everything, i magic lubed the o-ring just like a pool pump motor. Air Tight! Wouldn't have been the case if i had gone to the dealership.. Would've been whistling Dixie!!

Did same work with same problem hehe. Cleaned and Just bought a set of universal orings on the lokal carstore.
