I hate it sooo much when diagnostics and fixing is only about changing more and more parts (always at the cost of the customer), never KNOWING it will fix the issue, only always hoping. Have a weird, annoying issue with my off brand diesel car but I can't be made to just randomly start swapping parts until something fixes it. Great work guys on the Audi!
I’ve got an a4 and a Passat, always put the rear windows down in the a4 but never in the Passat! Great video, I’m a mechanic myself and never knew about the back pressure from the leak off? but every day is a learning day!
Pressure retention valve.. even replacing as a refresh on high mileage setups will give a new favorable feel. Restoring some lost efficiency and responsiveness is nice. I replaced mine on my ol' 2L cbea. Gave a restored feel, brilliant....always buy OEM.😎 Big cheers from Canada!
MARA for sure personally YES I do like the technical vids the most however you've only so much time. Smashing insight many thanks I'VE NO IDEA WHAT'S WHAT, I hope to catch you gentlemen soon as I've a big ol' problem I'm hoping you can sort.
I have a random injector imbalance code on every injector. Lol. All 6. I did replace this which I bought from an Audi tech. Now I'm wondering if this might be the problem. I only have issues when the MAF is plugged in. Unplugged it runs well and no injector imbalance.
Well Ryan legends so ye are. I can only imagine the heartache the customer was facing with this Q7 for all this time l would love to know how he decided to drop into you lads 😁. He must be like a kid in a candy store now with his Q7. Go on darkside. Love the channel Ryan as always ❤
How.. So that was the problem. That little plastic thingy. That goes to a T bolt. Recently the washers in the T was leaking on mine. I also replaced the little fuel hose that goes to that plastic part for to be sure.
WINDOWS................... in my A4 the driver's window had stopped working, it would open but getting it shut OH DEAR. However, yes the rear window switch is "RIGHT THERE" every time.
Can it be the same with my 3.0 tdi ASB engine it stalls at 3.3k rpm with no fault codes, I have new hpFp, checked the injectors all fine but car is not going higher than 3.3 k rpm afyer it gets warm(more than 80)

I have a 3.0 tdi a4 BKN engine code and if I drive mine into boost then change gear but if I try to put my foot down in 3rd or 4th at 1800rpm it’s dead and will not pull no power changed all the sensors. Turbo and had injectors cleaned and tested and I’m stumped
@@DarksideDevelopments I had the regulatorr changed and that jas helped massively but when I drive in eco mode it some times still goes in to limp mode but with no code
Great to be back to the old stuff......diagonistics and relevence to the common man 🙂
Yess, 30 seconds in and Ryan acknowledges that they don’t do technical videos anymore. Thanks! And keep these coming! 🤩 good seeing you again!
15' Q7 TDI owner here and I share the same pain when it comes to rolling the rear windows down first before the fronts. You're not the only one.

Spot on ! every day is a school day
I was literally thinking last night, I came to this channel to see the technical stuff and people’s project cars and your own project car builds etc.

Great to see more of the technical stuff that can cripple these engines.
Thanks.
I did guess fuel related but not the return pipes! Something learnt today 😁
Wishing could bring my A6 I to you guys it's driving me crazy feels like the wheels are going to fall off at speed
B9 S4 owner. When I first got it, I'd ALWAYS put the rear windows down first by accident!

Triple custard stag horn vents are cracked
great work and very interesting to see something like that would give those problems and nice to see a video that is not over land for a change 👍👍👍👍
these are the videos why i am here!
I thought it was that pipe even before you made the video 😂
Here for the technical vids 🤓👍
Lesson learned for the future!…
How fancy are you!!?? I don’t even have back windows in my R8!! 😂😂😉😉
Interesting! Also, I do the back window thing all the time in my A3 8P 😂
Had the same with a w166 and it was a faulty speed sensor wire.
Always end up pressing the rear window button too. Thought it was just me 😂
How expensive would this be to sort? Loving the more technical stuff keep it coming 😀

I pull the rear window on my A5 sport back very often.
As for the window switch position, e90/91 is the worst for that.

Brilliant video lads

For sure once you find a group of folk who are good at what they do, it's one of life's pleasures.
Really interesting. I like this type of video 👍🏽

Great job lads love these vids.
I was hoping to see Matt's purple a6 on here :)
Clogged inlet manifold and stuck swirlflap. Had same symptoms with my 3.0biTDi. Enginelight came on only when I stepped on gas hard.
watch the full video please!
My guess is leak off pipes and I am wondering if we are the throwing together remote guys
Haha I seem do put the rear window on my 7 series when meant to do front one 😂
Finally some tehnical stuff❤
Audi daily here. Window thing, every time....
Hello Ryan, are you talking about the fuel overflow hose as being the culprit.
That's the one
God damn this valve!
Haha yeah I always put my rear window down 😂
Have same Q7 always open rear windows
The window thing happens in my seat leon but not my octavia.
I Think it is the front Bell-end action up
Good video, tech stuff is great..I thought fueling but never something like the leak off pipes...technical diesels...and no codes...good work guys..👌💪
i have same propblem on my cayenne diesel 957. Must i change the o ring rubber seal at fuel return on injectors?
we usually do but you can try without
WINDOWS................... in my A4 the driver's window had stopped working, it would open but getting it shut OH DEAR. However, yes the rear window switch is "RIGHT THERE" every time.
Yes literally I had a a3 8p I use to be fine I just got a b9 a4 I’m forever putting the back window down at drive thrus ect 😂😂
Fab another victory. Sounded like a cheap fix outside of the diagnostic time
we diagnosed in 30mins! haha

Can this error also cause speed fluctuations in the stationary and low speed range?
potentially
I didn’t even know that thing was a thing

Best take a drive upto Barnsley then

Word of today” Chineseian”😂😂😂😂👍
Could this be the case for other VAG cars ?
Yeah, we first had it on a Transporter with a CFCA
If I took vitamins like I put the rear windows down for the fronts I would be in great health - ONE A DAY
Is this the same on a 2015 cnrb with the plastic manifold?
Any engine with Piezo injectors can potentially have this issue.
Front of the balance shaft come loose ?
Boost leak ?
Gearbox fault? Welp, I was wrong!
Dodgy torque converter?
Its abit like rough running/lack of power from the old mechanical piston pumps but that was because of a lack of pressure on the lift pump side
Could this fault show up asa low fuel pressure in rail fault?
Low fuel pressure is usually pressure sensor, fuel pump or injectors. When this issue occurred, there were no faults that came up so

Belle vidéo 👌 😉
Oh yeah, I knew that 🙄🤣
Perfect 😊
Do you do any tuning work on Mercedes diesel
We don't unfortunately
MAF or EGR?
Air mass meter
Is the bosch stuff any good?
Yeah but if you're replacing factory parts, buy cheap, buy twice
Flux capacitor
not an oracle 😂
The window switch thing happens to me all the time on my audi a6 c7
