Holy crap thank you !!! been chasing a leak for weeks!

[@jumperkenijn]

this is pure gold :p

31:29: Love that videotape buzz.

[@xMaGiiiqaBoii]

very helpful! thanks.

[@gjmaztr7]

great info for debugging a vw passat 1.8L /audi A4 ....OBDII fault code P0456 (*EVAP small leak exists) ...so checking a Vapor cannister purge valve, or a greyed out check valve, or fuel cap seal leak, or defective LDP in the drivers/passengers rear wheel well location.

[@insertname5365]

looks like a super reliable system to put on an already over complicated audi

[@adrianTNT]

24:12 "As you can see, testing the evap system is simple" :D

[@mrrobertwolfiii1079]

Thanks for the air back

[@obieoberstar]

I love the 1551

[@theMadSpektre]

That giant scan tool, that giant computer and CRT monitor... I'll bet their cell phones were HUGE!!!

Leak detection pump at 9:04

[@jwarnes71]

I took my gas cap seal off the cap and put a new chunky o ring in there. problem went away. I think the vw gas cap seal is engineered to fail.

I want to remove my clogged canister on my 04 jetta. One of the lines pulls a huge vacuum and im not sure what to do with it after disconnecting it.

[@grambosix]

nice vid. i am having problems on my 1.8T. it idles super rough ONLY after fill-up. runs perfect all other times. i know it's not the purge valve because i have tested it separately and it opens and closes fully. i have the "incorrect flow" code which means my MAF and/or O2 sensors cannot sense the fuel vapors from the canister/fuel tank. I have no leak codes shown. can someone help with some input please? i dunno what it could be.

[@yoadriaaannn]

I know this may be a long shot, 6 years long LOL but...did you ever figure what the problem was? I am having exactly the same issue on my 2016 golf gti. No codes related to evap and it only idles rough after fill-up, of course it then throws misfire codes because of the rough idling.

[@BMACVAGS]

Did you find out what was wrong with your car?

[@EXOVCDS]

Incorrect flow is usually a purge valve problem.

[@marcosmartin7618]

I need help with P2450 on my 2.5 2012 Volkswagen Jetta? Help me

[@lionheart100syd]

Exhaust Emissions Light always on in vw gti , due to this dodgy evap system, i have a vw gti and had to spend $800 just to get my evap emissions light switched off, got the charcoal canister replaced, purge 1 way valve replaced , N80 purge valve replaced... Due to this 'evap system'. Car was running as normal but emissions light was on until i got it fixed.

[@SydneyChromatic]

This is why people need to know just A Little about how cars work. Useless system. Just rip it out

[@johnvine5731]

A cheap way to resolve the problem is to remove the emissions led or bulb.

[@marysoltejada]

V W JETTA 2012 2.OL CODE P240A EMISION SYSTEAM LEAK ?

[@docforti]

my rpm as seen in video response isnt stable >> may this a problem of charcoal canister ?

[@SydneyChromatic]

Boost leak

[@SydneyChromatic]

Vacuum leak

[@adrianTNT]

I think chances that a mechanic knows/understands all this is under 1%.

[@AnonYmous-gw5it]

I'm a retired airline mechanic and I understood it perfectly first time through. You need to get out more and meet more mechanics tough guy.

[@DaytonCarCare]

@@AnonYmous-gw5it Yeah they think mechanics are all morons until their car breaks down then you're a miracle worker LMAO

[@valsotto27]

is this a big deal if its not changed?

[@SydneyChromatic]

Snowflakes cry

[@PanamaSticks]

I've paid hundreds of dollars to repair the MONITORING circuits on cars that had no leaks. Why add these expensive, complex, and failure prone systems to every car? Do the monitoring of emission control systems at the inspection stations and let owners drive their cars without being tormented by this stuff.

[@SydneyChromatic]

Just rip it All OUT

[@mrrobertwolfiii1079]

See research what your into

[@mrrobertwolfiii1079]

See even I had to ask museum search and development for a million dollar fifty million dollar donations. Between two thousand and two and two thousand twenty two

[@Avenging.angel.no1]

Look at the size of the diagnostic tool.. 😂

[@martymcgrogan]

Thanks for a nice public service, but I am sorry I own my Passat, truthfully, because it is so over-engineered, the owner is forced through the inherent complexity of all its systems, to return to the dealer and bend over for a good pile driving. It was designed to require dealer involvement often, and they are merciless in their charges for parts and labor. I am going Japanese or Korean or USA from this point on.

[@tonydebreceni8966]

What a poorly designed mess

[@tempest411]

LDP? ORVR? Good Lord...Those idiots at the California Air Resources Board ought to be exiled from the U.S. for coming up with this crap and forcing it down the throats of all the manufacturers and consumers.

[@tonydebreceni8966]

Save your money, dont buy a volkswagen.

[@SunRunner-TVchannel]

Garbage. Delete EVAP . Go to back in 60-70 ;)

[@themachine8009]

This is too technical for me. I’m not that smart

[@wandameadows5736]

The most unnecessary system on a car. All you need is a "cat" & the rest is overkill that cost citizens a ton of $$. Most of the $$ spent by consumers on car repairs have nothing to do with the automobiles ability to function as a transporting machine.

[@jwarnes71]

dude needs a diet

[@p76588ersfg]

удалил эту систему vw . чуть бензобак не схлопнулся
