DSG DQ400, p2884. Replace or easy fix?
HTML-код
- Опубликовано: 4 дек 2023
- In this video we diagnose an Audi e-tron with a DSG DQ400 transmission problem. The faultcode stored is p2884 and VW/Audi tells us to replace the mechatronic. But do we need to or can we fix it?

Why you are smelling like transmissions fluid havent you bathed🤣🤫
German engineering has become ridiculous.Only Rube Goldberg would be impressed.
What was the price difference from replacing the whole unit vs just replacing the valve?
Thank you Dan. Was very helpful
The topdon links don't load! Do you mind sending us the model?
Lord, if only all repair shops were as able and honest as Diagnose Dan! It's amazing to me how our transportation system relies on a repair system that is so hit or miss and fraught with ineptitude. It really is a crapshoot to get your car "repaired" these days. It would be magnificent if Dan and others like him could create a school/system of schools to educate pupils on the fine art of diagnosis and repair as a university degree. Now THAT would be a guarantee of a good job anywhere on the planet, and society would benefit hugely.
It would be nice if costumers we not so ignorant and didn't want free shit all the time
Thats why I repair my cars myself. If I mess up it will be my f-up, not someone else's.
No sweat guy!!!
Two or so more generations, and it will all become clear to laymen...😅
@@bleachinurimaybe, but in this case it would be nice if Audi could offer an actual repair instead of saying "just throw the whole unit in there, sure it's only three grand and it's not my money".
And that's why they're called Main Stealers.
We have such a system of training in Australia for apprentices to become Tradesmen but that does not dictate aptitude nor competency nor does it dictate scruples or negate greedy/lazy practices in this industry. The individual desire to be better and do better is subjective and random, there are not enough competent and committed persons with high moral standards to go around it seems, the quick buck and the reluctance to admit fault or lack of knowledge sinks a lot of transactions between workshops and car owners, sadly the standard of business ethics and individuals ethics seems to be waning at the industries and owners lament.
We are happy to support you in this diagnose Dan!
Nice work ATR 👏👏 A fantastic article that was shared
Thanks Sam👍👍
Great work
Thanks, Dan. This is really a scandal. The gasket is defective, the screen falls out, the solenoid becomes plugged and the manufacturer sells a part for €2k to correct the problem. Sounds like a solid basis for a date in court. Thanks for this very understandable and clear explanation of what happens. As always a win.
Also a pretty NL problem, the importer here PON takes over the warranty from VW to get a higher margin (they also swap the conti tires with other brands like nexen). So some defects that are covered by VW Germany outside warranty won't be covered in NL, saw this with EGR and chain issues.The classic PON thing is also you are the "first" with this issue while half the lot is full of cars with the same issue.
Agreed. This needs to be a recall, frankly.
This might be the reason that VW and Audi are telling you to change the mechatronic and dont explain what goes wrong.
@@f0x4nn3we've never seen this before 🤣 sounds familiar
@@jimtaylor431agreed
Typical dealer replace not repair great to see people like you that give us hope of repairing our own vehicles at a fraction of the cost, great video once again Dan looking forward to the next one.
its a lability for a dealership to repair anything except under warranty and is recommend by the manufacturer
@@mrjamrocker7813 And the poor customer gets screwed big time.
Thank you
I recently purchased a 2020 Skoda Octavia and heard enough horror stories about VAG DSG transmissions to make sure I bought one with a 6-speed manual box. Videos like this make me feel even better about my decision.
Imagine if you could've got a plugin hybrid with a manual!
The DSG is typically very reliable in the standard gasoline/petrol and diesel engines. The biggest failure in these are typically the owner who doesn't maintain it with scheduled fluid changes. However, you made a good choice with the 6-speed. The VAG manual is really nice and there are a ton of options to change the ratio of the gear shift if you want a shorter throw.
Nah, I miss my Octavia 2.0 Petrol with 6 speed DSG ...
You should bought a car with ZF 8HP transmission! Auto and no problems! I recently purchased a 2020 BMW with ZF 8HP box!
Yes, but no, but yes. If you have a DSG especially with the dry clutches i recommend to let reprogram the DSG to shift at higher RPM. The low RPM it already shifts puts quite a lot of extra wear and tear on the clutches.
Other then that it's for sure the most comfy automatic.
Unbelievable... the shitty build quality VAG keeps delivering.. You are the man Dan! Love how you fix it without throwing away half the engine.
Gasket part reads "China".... That surely has nothing to do with the problem.
TBH every modern car is pretty sensitive, issue i run in with VW is they actually not take care of their customers when shit happens. Timing chain has worn out at 50.000km and 3 year... sucks to be you here is the bill.
Thanks!!!
@@SerbanCMusca-ut8nyindeed it has nothing to do with China, its up to VAG to do its quality control and no one else.
@@f0x4nn3interval for changing timing chains or belts, doesn't matter, it's relative to the type of driving that you do. So if you mostly drive in cities, with congested traffic, short trips, sporty style of driving, that interval drops. Many problems can be avoided by regular maintenance.
@Diagnosedan it's hilarious that the filter screen designed to stop debris entering the solenoid is actually the culprit. I think Audi should be fixing this with a recall, clearly there is a manufacturing defect with that gasket from new, great work as always Dan 😊
Agreed!
Not a manufacturing defect but a design defect. K0 needs a bigger supply of oil, the extra force on the mesh flexes it to the point of fatigue failure. A larger orifice might be the answer.
Dan. You have managed to yet again demistify a very complex set of vehicle systems and break it down into very understandable sections, with solid repair options that can save the customer a lot of money. I love the recap and then the suggestion of the much cheaper preventative gasket change to stop this problem before it starts.
Preventing is better than repairing😉
Fantastic once again Dan.
I audit VWG dealerships in Scotland and have referred technicians to your website many times.
I hope you got a beer. Cheers
Thank you! Its appriciated
DSG has such a stellar reputation for reliability.
🤣🤣
This attitude from manufacturers is completely nuts. Cudos Dan for showing how to troubleshoot and how actual mechanics actually CAN repair things - not just swap out parts!
It's how manufacturers make huge amounts of money on spare parts. Anything that goes wrong on a car these days is going to cost a fortune.
Looking at the quality of work of most workshops I have seen, VAG might be correct to suggest to swap the part. There are are probably quite a few things you can do wrong repairing it yourself. Also who knows if the upgraded unit also solves other design flaws…
Thanks for the great comment
@@felixalbionthey make a lot more money on parts than on selling new cars
@@random123name1less that can go wrong indeed.
Fantastic ! What a waste to throw away such a complicatedly made piece of engineered metal when it could be repaired and reused. Enjoy the beers Sam and Dan !
You're more likely to run into Bigfoot than a hybrid owner that actually saved money over the long haul vs a standard ICE car. Nice work Dan!
There are many hybrid owners that save money over the long haul. They drive Toyotas. 😉
@@JeroenvanMontfortI know a few Camry Hybrid owners which learned the hard way how expensive Hybrids become once the warranty runs out. Some now drive Teslas.
@@moestrei lol really? I drive a Tesla myself and it has made me question my life's choices more than once. Especially now it's out of warranty...
Outstanding. You explained what goes wrong, why, what to do to repair it and what NOT to do and why. That's the way to teach. Not many people do that. I am learning heaps about electronics also mechatronics, stuff that I shied away from. Well done. Supposedly retired 72 yr old mechanic/machinist in Land Down Under.
Gidday mate! Shoutout from Germany. I love your country. Hope I will be back there some day.
Thanks for your great comment, i'm coming down under 🇳🇿 in April at the AAAA in Melbourne
Great video and fix.I will make an effort to come and say hello at the AAA show.Now retired after 40 years as a transmission shop owner in Melbourne.@@Diagnosedan
My goodness. What a great team effort. Outstanding presentation Dan !
Thanks as always!!!!
this has to rank amongst the best of your 'super-fixes' .. great job Dan
Thanks!!!👍👍
Second video I've watched this week where an oil screen had disintegrated and jammed a solenoid. Ivan from Pine hollow Auto Diagnostics had one on a VVT phaser. Great content as always Dan.
Was that also a Vw/Audi?
You’re one of the best technicians in the world, you should be very proud of what you do.
Thank you!
I enjoyed your troubleshooting as usual. It is a lot cheaper to repair than to replace the whole thing. I call that a mechanic and not just a part replacement, a mechanic like in the old days. 💪
Not sure how cheap it would be if you pay a garage to do it. The labour charges will still cost a fortune.
In this case it certainly is
@@felixalbionnot cheap but alot less expensive.
Audi ought to be paying for this .
They usually fail just outside the waranty period 😬
One if the best diagnosticians out there. Truly the G.O.A.T. I absolutely love the bloopers at the end too. 😅
Thank you!!!!
Somebody GET this man more SUBSCRIBERS...Spread the word make him a household name...😅 He has earned it...and then some!
As for manufacturers who KNOW about issues like this and still don't do what is right...they should be prosecuted. But the law-makers are asleep at the wheel as always. Imagine if they passed a law that forces any manufacturer to provide a MINIMUM 10 YEAR WARANTY on their vehicles... how they would start making cars as good as they used to...or better...oh well, one can dream at least!
Thank you Dan... yet again!
Thanks for your comment!
Good job. I wish all repair shops had your ability and honesty.
Dan, thank you for your time and interest. You are as good to us here on RUclips as you are to the customers whose cars you repair. Even if we are not active in the automotive field, it is nice to see how certain technology works and how defects can be eliminated. Success 🇷🇴
Thanks for the great comment!!!
Dan. You have yet again managed to diagnose and repair a very complex system in a step by step guide, with a recap as well. Such outstanding work as always, explained in such a way that makes it easy to both understand and follow. I love the tip of how to prevent this occurring in the first place. Dan definitely "does it again" Well done sir! 👌🏼
Thanks!!!
Dan thats great information and a brilliant find 👍
Dan, I don't think the customer would mind paying for that case of beer since this fix saved them a lot of money. 😉
Love how excited Dan gets when he figures out an issue (with some help in this case). It's clear he enjoys problem solving. This is exactly what you want from a technician. Keep the great videos coming Dan.
I can't stand "not knowing" 😂
What a great fix, but I doubt whether even an authorised VAG dealer would bother to go as far, but just replace the mechatronics unit as a whole. Shame, really… Good to see you providing the fix details, Dan and great to see the old fashioned method of pals payments is still going strong! Nice one, Dan! 👏👏👏
I guess its to "risky" and alot can go wrong😊
Amazing diagnosis and tear down. In addition it shows the compounding effect of community knowledge and experience. Dan you are certainly a leader and influencer in your field of work. As usual….DIAGNOSE DAN FIX IT AGAIN!!! And man Audi loves cheap oil screens that break. Geez.
Thank you very much!!!
FANTASTIC! Super diagnostics. Always fantastic to watch Dan.
Thank you very much
way to go the extra kilometer to get to the bottom of this problem. great diag as always Dan!! love the videos that do deep dives into repairs that can also save $$$. hopefully some day we can do a diagnostic and share a beer TOGETHER!
Thank you very much Mike, i really hope we can do that one day!
Awesome video. This will save a lot of time and money to many technicians.
The problem you have highlighted Dan should be accepted by the manufacturer as a recall. A relatively easy fix compared to replacing the whole unit at mega cost. The manufacturer needs to save face and accept that the issue falls well below their usual standards of engineering. Thanks Dan for highlighting the issue
In none of their documentation they say anything about the screen failing. Although they certainly know about this. I dont think this is a coincidence
@@Diagnosedan Unfortunately they always choose to save money , they know this issue would be investigated if they mention what fails
But its only a"fix" for another 60,000kms ??.... in my eyes thats not a fix and even a replacement Mechatronic unit is not solving what is in fact a design fault...🤔
@@peterfitzpatrick7032 Dan said that the replacement Mechatronic unit was an upgraded unit by the manufacturer. Presumably the manufacturer has “removed” the initial problem highlighted by Dan. With this in mind possibly the transmission should have a “long and healthy life?” Fingers crossed for the owners of the vehicles
@@ianbates1312 if they "removed" the problem, you would assume the new gasket would not have the screen at that location. But this new gasket did.
Amazing info, Dan. I always learn so much with you. I love how you want to dig deeper and learn how and why a part fails, instead of just replacing the part. Thanks for your amazing videos.
Love how you can always make super complicated topics easy to understand. Top quality work
I'm always trying to keep it simple!! No need to complicate things😊
Dan, what will the rest of us do without guys like you and others that share their hours of sweet and labour with us?
You'll figure it out yourself eventually it just takes more time😂
Thanks Dan. Great job again. Just tells me to never ever buy a hybrid. The extra mileage is not worth the hassle.
In some countries the reason for buying Hybrid or electric is because there are huge tax benefits!!
Not all hybrids are born equal. Think Toyota hybrid system. No gearbox, no turbo, no problem.
Once Dan came out with a new video, I stopped what I was doing and watched it. Best technical channel on the internet
Absolutely brilliant ,i get more enjoyment from finding what things failed rather than replace and move on,thanks
We learn, learn and learn again!!! But the most beautiful feeling that Dan conveys to us is joy!!! The joy, success, success of the repair. It's very easy to say "it doesn't work", sometimes it's quite difficult to fix it. But, in the end, the joy is worth it! Good luck Dan!!! We look forward to the next "joy" you share with us!
Thank you for your great and positive comment its really appreciated
Great work Dan. A top class instructional video as usual. Thank you
Thanks!
Amazing diagnostic,Sir you are an excellent teacher
Thank you
This was a great vid as usual. For twenty years of my automotive career, I was Automatic transmissions only. That was 23 years ago. A lot has changed since then.
Hi Bill great to see you here in the comments again! Its appriciated 👍
Thanks, Dan, now it just needs someone to remanufacture that screen in a more robust way and you won't have to keep replacing it. I enjoy your videos and the fact that you provide an independent solution to manufacturers faults.
That should be a recall issue at manufacturer expense. One thing you did not mention is how much is saved by repairing the unit instead of replacing the unit.
On parts, $30 euros vs. $3,000
@@Garth2011The working hours are the same in both cases, aren't they?
@@leiflillandt1488I'd say the repair had more time.
@@leiflillandt1488 You would think a couple of extra hours on the repair would do it.
@@Garth2011 more time and a bit more risk too. If a bit of the failed screen doesn't get cleaned out properly, it could scratch the new solenoid, etc.
Outstanding once again Dan, always explained perfectly 👍🏼👍🏼
Thank you very much
Dan, your approach, knowledge and enthusiasm are humbling. Thank you.
Thanks!
Excellent job and your group of electronic genius's should be very proud at what they do. Thank you again
Thank you Richard!!!
So what is the cost differential in both financial and time, between replacing the whole unit as noted by Audi and going through the extra repair and parts steps to replace the solenoid?
Again, you are the master of the "rings" of diagnose. Much respect!
🤣🤣Thanks!
I love the way you explain stuff properly and simply, I'm not a mechanic but have been fixing cars and bikes for my self since I was a kid and it's great to have guys like you online to help folk like me develop new skills. thanks
Thats great to hear!
Dan, Brilliant Fix! So many times the Manufacturers want to change expensive Modules instead of fixing the individual components. That situation is very similar to VVTI Selinoids that get gummed up with neglected oil changes. Sometimes you can clean them an no parts required. Was the oil contaminated in the megatronic to cause extra pressure to make the screen fail? Could it been prevented by changing that oil more often?
There is no contamination on the other screens. I suspect the screen fails because of pulsations in the oil when the solenoid is doing its thing
Where do i get The solenoid. The vw dont sell it?
I'm glad that there are technicians like you and sam thank you again for a great vlog from a old tech 👍🦘🇦🇺
Thank you!!
Dan is one hell of a great guy and mechanic! I would still be driving my S3 if I had Sam as my mechanic, but mechanics like this are a very rare find.
I had a few VWs back in the states with the DSG. Great transmission but it has the potential to be disastrous. And especially most people in the states don’t do the required transmission service since it’s expensive.
You just nailed it. The owner is the worst part of a DSG. So the maintenance and it will last the life of the car and be able to be transplanted into another car. Don't do the maintenance and it is an expensive out of warranty repair.
@@Birdman_in_CLE thanks! I just bought another VW back in Florida (video coming soon) and I avoided the DSG transmission for this very reason! Went with a 2.5L with the regular 6A
"And especially most people in the states don’t do the required transmission service since it’s expensive". This is like not eating because it is expensive.
@@guzziwheeler cars are appliances there. People generally don’t take great care of them. Especially when maintenance is expensive
is there a bulletin for owner to clean the garbage under the windscreen ?
Good morning from the Jersey shore, USA 🇺🇸 our industry needs more of what you do Dan. Excellent presentation and diagnosis as always. Thank you for what you do but more importantly, thank you for what you share. Hope all is well
Thanks for your great comment!!! Its really appreciated
A view from the UK. What i find fascinating about this channel is that it gives us an insight into todays cars. I gotta tell ya i've never seen such complicated mechanic/hydraulic mechanisms in all my life. The manufacturing process itself to make all those die cast manifolds. The precision grinding of solenoid plungers. The process to make multi functional gaskets etc. Not least of which is the design process to get all of this under the bonnet. All to do what? Get you from A to B., in a semi "environmental" way. I've told Dan before, the more you put in something, the more it can go wrong.
BTW., a "screen" is really another word for filter and in the days when we had grown ups designing things, filters were ALWAYS easily accessible for replacement, not hidden away in the depths that cost £1000s' to replace AND if a pattern of failure was seen then the manufacturer went straight into re-design mode. I get the feeling Dan from your demeanour that these are just acceptable, everyday faults that are part of todays cars. So much so you and your mates even write fault bulletins. I wonder, do you send one back to Audi/VAG/VW perchance?
It all looks easy accessible when the engineer designed it on his laptop😂
Thats an amazing job Dan, i wish main dealers would fix these components , rather than just firing the parts canon. It is better for your wallet, and the environment too.
On what way did an engineer feel it's ok to fill through the drain.
my wife's Citroen is the same 🙄
That is quite normal. An overflow tube is an easy way ensure correct oil level. Same on my Mercedes.
Most manual transmissions and rear diffs are filled the same way. Fill until the oil overflows.
@@kain0m Those that I have come across have a fill/level plug in the side ie you fill it to the level of the hole in the side of the gearbox or diff. That is different from the overflow tube in the bottom of this DSG g/box
I love you Dan, you made the repair simple, I keep learning from you
Good explanation of a problem with a recommendation by a car repair man. The best problem is no problem and since the problem is intrinsic in the design the alternate way to prevent the problem is to replace the Audi hybrid with any vehicle that doesn't have that issue- perhaps one without a transmission.😁
Now Audi is going to make it so you can't buy just the solenoid.

100,000 Kilometers or 62,500 Odometer Miles. Knowing this, like you I suggest making this part of Periodic Maintenance at every 50,000 Odomer Miles or 80,000 Kilometers.
Plus with the fresh fluid change, your helping to extend the life of the unit.
Your fluid change procedure is very similar to my 2020 Toyota RAV4 Non Hybrid with an 8 Speed automatic transmission. The Car Care Nut or TCCN has a procedure for changing the fluid in his You Tube Videos.
Thank you for this video Dan!

Thats fantastic to hear! Thank you
Another wonderful video from a master mechanic!
Thanks!
Very clear explanation of the root cause of the problem and how to fix it properly.
I will admit my first thoughts were to clean and re-use the solenoid AND to drill out the screen on the new gasket. DD explains clearly why not! Obvious once explained but soooo easy to miss out that vital stuff.
Nice job!
We learned the hard way😂
