How to Use Smoke Tester to Find EVAP leaks | Audi 2.0T P0455 & P0456 Common Cause | Ancel 1000 Smoke

eManual Repair Manuals for Any Vehicle - shrsl.com/43l4o
In today's video we are testing this 2009 Audi A4 2.0T for vacuum leaks after having several fault codes showing up. A vacuum leak not only causes a Evap Error codes to appear, but can also cause misfiring, rough idle, poor mpg, and even put your beloved car into LIMP mode in an effort to protect itself.
A vacuum leak allows too much oxygen to enter the system past the critical sensors usually. So now all these sensors are having a false reading or trying to compensate for this extra air in the system. This is why your car can run so rough when this happens.
Often times folks just start replacing parts. Replacing hundreds of dollars' worth of parts only to have the same issue pop up since it was a vacuum leak the whole time. A smoke tester is a cheap way to properly diagnose your car BEFORE you start replacing parts. I wish I had one of these much sooner!
Here is the Ancel Smoke Tester from Amazon used in the video - amzn.to/3itL4fm
Here is the upgraded version as well - amzn.to/3H20OR8
Professional version if you real fancy - amzn.to/3H0l2dR
Here is a cheaper one if you a broke like me - amzn.to/3VEyMiO

I’m so happy with how easy these parts are to change

[@user-yc4gy3er1n]

the cap on back can i replace that clamp w a screw on hose clamp or does it have to be crimped

[@MarzNet256]

Cool. I just picked up this unit for 93 bucks and it came with a free inflatable bladder as a promotion.

[@Mechani_Cole]

That's awesome. Thanks for sharing🫡
Great little tester!

[@RedEyedJedi]

I think that's the same 2.0 tsi engine I have in my Scirocco. I have the exact intake manifold but that rubber part you took off is not on my manifold for some reason.

[@Mechani_Cole]

If it's not there you can use the intake or any other port leading in

[@RedEyedJedi]

@@Mechani_Cole Thanks man, I appreciate it.

[@troymiller319]

Where do you connect for evap? 455 error. Large leak

[@Mechani_Cole]

Locate the evap service port of your vehicle, make and model, and then insert it in there. It should have a little screw cap on it like a tire valve stem

[@MrtalentedReid]

Awesome

[@kastromario8514]

I said that this type of machine also works for gasoline leaks I would like to know in which hose to put the smoke

[@Mechani_Cole]

Pretty much any fuel line. But you should be able to see the gas coming out too

[@mikemasso9530]

A quick note on these Chinese evap testers. They put out way to much pressure
for evap testing. The maximum pressure for the evap system is .5 psi or around
13.0 in. H20. The Ancel is putting out way over .5 psi. Anything over 7 psi
can damage pressure sensors and or blow off hoses. 14 psi is OK for intake
and exhaust testing but way to high for evap.

[@Mechani_Cole]

This will not and has not damaged any sensors or blew any hoses off in the 8 years that I have been smoke testing. Most people know not to run it full blast. But if an evap smoke test blew a hose or a sensor, then clearly there was other issues at hand

[@electric8668]

Mineral oil works just as well and cheaper than baby oil.

[@Mechani_Cole]

I used what I had so it was free

[@electric8668]

@Mechani_Cole Great I was just letting others know of another option.

[@ollietheboy7107]

I prefer the stogie method

[@Mechani_Cole]

Me too! Lol, I actually have a clip I wish I could upload where I made a smoke tester out of an air mattress pump and a large GREEN bowl for smoke haha

[@RomanTrollanski]

You could find with air compressor included for same money.

[@Mechani_Cole]

Yeah I did notice some of those too, pretty cool👍🏻

[@NhatNguyen-xs7kl]

Can you send a link for one? Thanks

[@Mechani_Cole]

I recently just got this one with a built in compressor, pretty nice! amzn.to/3SJou0Q

[@user-yc4gy3er1n]

the cap on back can i replace that clamp w a screw on hose clamp or does it have to be crimped

[@Mechani_Cole]

Regular clamp works just fine
