VW 2.0T TSI - Compression Test
HTML-код
- Опубликовано: 8 сен 2024
- In this video we do a compression test on the Mk5 2.0T Jetta Wolfsburg after re-building the engine. We rebuilt the engine after a 3rd to 2nd gear mis-shift (rebuild video coming soon). We already have 1000 km's on the rebuilt engine, so it's time to check out how healthy it's running. We have no fluid loss or oil consumption issues to report, so it looks like the rebuild was successful. Enjoy the video! Please like, share, and subscribe :)

My 11 year old TFSI (Octavia MKII, 316.000km) with original motor (CCZA): 12-12-12.5-13bar. :)
These engines just last eh
Great to see another video guys, good luck with the mazda too!
massive help cheers fellas.
Cheers!
Dude I have a cuestion, the test compression need do it with open troltle pedal or not
That's a great question. Once the fuel injectors are unplugged, I think that's a great idea to ensure enough air gets in there. Maybe compare the results with the throttle closed, and the throttle open.
Curious can’t you just pull the fuse for the fuel pump?
If I recall correctly, it would skew the readings as the fuel injectors would still open causing a path for cylinder pressure to escape
where is the vid of that rebuild? Id like to see that. I liked the K04 install.
haha thanks! It's actually coming up really soon! Julian's had it on the back burner for a while but it will be out shortly :)
Hello chaps from England! Good fun channel and I have a 2009 TSI in a Skoda Octavia MK2 which I found your channel after my intake balance shaft took a dump on track. Also been doing all the work on my drive in the same way you work on the Jetta. Decided to get a k04 hybrid now which is sat in a box ready to go on in a week or so. I'll blame you guys for that 🤣
Beautiful!
My 10 year old TSI has 135-150 psi... with the injectors plugged in and cold. Do you reckon it will go up with the fuel injectors disconnected and engine hotter?
It should definitely go up with the engine hot, and the injectors shouldn't be spraying when doing a compression test, so definitely have them unplugged. Also with them plugged in, we're thinking that air pressure can potentially leak into the fuel circuit through the injector nozzles when they open.
I have a love hate relationship with the EA888 2.0 TSI
100% Agree with you, It's great when it's not broken :) and it's not fun to work on with all of the "one time use" parts.
What is a healthy compression test numbers or a 2.0 TSI mk5 gti 2009
From what I've read anywhere between 160 - 200 psi
Bro, were you at the ertefa meet at the canadian tire plaza few years back? Shit was rowdy.
Haha must have been someone else. Why what was happenning?
hello greetings from Spain I have a question I have a 2.0 tsi golf 6 gti that I get p0300 only at idle paraparadanado and the fault goes away change coil spark plugs injectors intake manifold but the fault continues I did a compression test and they give me all 12 bars except one that gives 10 bars that is in the limit could you help me gracias un saludo
Did you find the issue in the end
Hi, can you help me ?
My compression is cylinder 1,2,4 - 200psi . cylinder 3 - 160psi ..
after spark plug explode at 120mph
same ea888 2.0 tsi (CCZ engine)
do you think i need to build the engine ?
Check out our Leak Down Test video here: ( ruclips.net/video/An59jjeSJt0/видео.html ) It's possible that broken spark plug fragments might have damaged the engine causing a loss of compression somewhere in that cylinder. Doing a Leak Down Test will allow you to determine what part of the engine is leaking compression. Hope that helps! Let us know what you find :)
ON THISE CONNECTORS, JUST PUSH THEM IN THEN PULL AND THEY COME RIGHT OUT!
Haha yeah gotta love VW
Question for you. Have you ever gotten a code p0069? I replaced my bar map sensor my old one went bad Bad it was the corksport 3.5 I got a Bosch 3.5 now and that code p0069 came up all connections look to be fine
I'm wondering if the scalars in the tune are different for both sensors. Have you contacted your Tuner about this?
Wannabe Tuners yes I just contacted him he recommended get a new one of the one that went bad and test it
@@israelcarrillo1664 Oh so you're going to try a new Corksport 3.5 bar map sensor?
Wannabe Tuners yes I was recommended to buy a new one or he could make some adjustments to my tune
I thought you had to unplug pcv valve to simulate WOT as well?
The combustion chamber is closed completely during the firing event, regardless if at idle or WOT
Good job bro
Didn't you already do a compression test?
NVM should have watched the vid before I spoke 😂
@@westmountainmotorsports haha no worries :). We did a leak down test before we blew it, but never a compression test on this motor.
@@WannabeTuners was this Jetta stage 2 before you guys went k04? If so how does it compare?
@@westmountainmotorsports yup! It was eurodyne stage 2 for a while. The lag between the k03 and K04 is not that noticeable, it spools quick. There is a stronger punch in the midrange and top end but it dies down near redline. Needs more flow! Should have gone with a gtx2871r or bigger after stage 2, but that's where it gets expensive lol.
@@WannabeTuners yeah those big turbo setups are expensive but work great on these engines. Skip k04 then?
Wanna be fo sho.
The starter is right there. Jump it...

Thats still fairly decent? Was issue with cylinders or injectors?
Maybe this is a dumb question, but...
Rather than messing with that connector, why not just pull the fuse for the fuel pump?
Yeah we tried that, but doing it that way allows the injectors to open during the compression test which allows pressure inside the cylinders to vent into the injector nozzles causing low compression readings. We looked up the workshop procedure, which outlines that the fuel injector connector needs to be disconnected.
