2009 Audi A4 2.0T Engine Misfire Fix And Intake Manifold Removal

[@JohnGriffithJr]

OK, yes this was a good instructional video. No skipping the painful, tedious steps. No time lapse videography. The real thing just like you were there getting your fingers dirty. Thank you.

[@shotbyqory3161]

Right

[@jessesward9429]

Just got done will a full day working on cars, time to watch Nathan work on cars

[@ButtKickersReviews]

Same lol

[@DuaneMoore]

Audi are such beautiful cars( the new ones) nightmare (rs6 ) to work on . Good job Nate Jack of all cars .

[@jerryx2000]

Hey man I want your honest opinion. I own the A4 B8 2.0 TFSI since 2011. The engine was using 1l oil per 1000km. I got a new Audi motor in 2014 for free as the car was under warranty. Since then no oil usage, just the cooler went bad in 2020. Now the car has 190,000km & it is running perfect. Would you sell the car or keep it for another 200,000km?

[@harley5803]

Keep it forever

[@jppoolcleaners]

What was the issue that caused the Misfire? Was there a crack in the intake manifold that was causing the misfire?

[@sufyanumar4663]

My 2009 Audi A4 Avant is misfiring on idle but slowly starting to misfire when I'm driving now. Will I need to change the injectors?

[@ranbirrana3993]

Your video is informative. Curious what causes to replace hpfp?

[@ruslik91]

Why you testing without remove all spark plugs from 1st cilynder. if there air bridge between 1st and 2nd cilynder you can see wrong compression bars.

[@blakeamathews10]

Sorry if this isn't the best place to ask for help lol, but I'm at my wits end, I've been troubleshooting, fixing and finicking with her for months now. I have a 2013 e93 with the n55. Randomly one day a while back she started having a random misfire in just cylinder 6 with no real reason as to why, and a rough idle, I've replaced the spark plugs with 2 step colder, the ignition coils are brand new and that seemed to help a lot, ran injector cleaner through her a couple times, and New MAF, I am in a pretty serious club so she gets her spirited driving in almost every week, and tats what through me off, the misfire is totally random. And only ever at higher rpm at higher gears, I have a manual so I can confidently say now it only happens sometimes above 4 rpm in 5th or 6th gear and almost always pops up if I'm going up a hill, I'm running jb4 and have never seen any codes to point me in a direction which is also wierd to me, catless dp's, and bms intake are the only major engine mods I've got in her, the rough idle I'm fine with, I can live with that, but I've been chasing this misfire so long I'm resorting to commenting on KZbin, please someone help lol

[@andyb6851]

There are some youtubers like BMW Doctor that do paid consultation, much cheaper than going to a US mechanic. I'd really suggest going for something like that, just do the usual like smoke test for vacuum leaks, look inside and compression test cylinder 6. Also do what Chaminda said.

[@tonka10r99]

Did you gap the spark plugs to the correct inch?

[@mikimiki195]

Yeah Nate is back fixing stuff 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

[@quincybattle9458]

I have a 2013 a6 3.0 supercharged that’s misfiring all on bank 1 and it’s displaying all the symptoms of this car, any ideas ?

[@ElRayDelRio]

Same has been happening to my C7. Ive replaced plugs, coils, ait, maf, map, boost solenoid, 02 sensors, pcv & air filter. These all seemed to help the car but I also believe I have bad fuel injectors and need a carbon cleaning now that the car has over 120k miles. I did BG44k topend fuel cleaner which did help but I think its time the intake manifold come off and walnut blast valves.

[@R3MILI]

Ive a a6 2007 2.7 diesel with manifold intake problem . Ive done all filters and oil change , but it consume 10 lit for 30 km in city . I dont know how much has consumed before becose ive buy it 1 month ago , with 255 000 km . In highway it consume 8 lit . It has even some code rfor injector 2 3 5 . If i use diesel moly purge directly in fuel filter and if i buy new intake manifold , will it consume 30% less or not ? What do you think , give me any advice

[@mickmolloy6594]

So did you replace all the injectors or just cylinder 1 injector?

[@snoopy5736]

All

[@GiotheGhreat]

Hi. My 2016 A5 2.0 is jerking when I come to stop. Sometimes it goes away and comes back. No CEL or pending codes. What to do when there is NO CEL on? Should I keep driving it? I did common maintenance + New coils and spark plugs. Ca has 50K miles only. I never floor it or race because is a sedan

[@christoledo5217]

Did you had to program the injector?

[@andyb6851]

That went nicely, when I saw the spark plug being on so tight I had a feeling there will be other surprises. So there's no use in trying to clean the injectors, better just buy new ones?

[@NathansBMWWorkshop]

They are cheap enough not worth cleaning , and prob has plunger issues inside the injector

[@R3MILI]

Hello , ive a a6 2007 2.7 with bad intake manifold code . Car consume 10 lit in 30 km city , does it consume so much becouse the intake manifold ? In highway 7lit/100km

[@samoniumuziejus]

I get P2015 but the manifold flap looks fine, what othrr parts could that code signal ? Manifold sensor itself ?

[@kirkbanton9181]

It would be nice to see you working on more customer vehicles.

[@231mac]

Try to disconnect the injectors/fuel pump before doing a comp test as the raw fuel help seal the rings and artificially inflate a cylinder's PSI.

[@gutzu265]

4.00 is that excess fuel shooting from the cylinder with the bad Injector?

[@tonym-so4tt]

2010 a4 I’m in the military stationed in Korea and car runs rough and in traffic it cuts off when rpm are low,I brought it to audi here and the can’t find the issue.I had changed camshaft and crankshaft valve and cleaned the throttle body coil packs cleaned fuel pump and injection still having issues please help thank you

[@oso2916]

Do you need to program the fuel injectors ?

[@FloridaBikeSupplyOnline]

@ 18:33 Do you know the name of the valve under the oil filter? I've been trying to find new o-rings to fit it, but thinking I'll just buy a new one. The closest I've found to a name or part number is "oil filter adapter valve" for a 2017 A4. I have a 2011 a4. Great video! Cheers!

[@robertoalvarez7960]

Oil, filter, housing gasket

[@fastboatster]

Another note on how easy it is to work on b8 Audis is that on 2010+ you’ll officially have to disconnect the ac lines to replace the coolant radiator or grind of some tabs on the radiator. Also, if you haven’t noticed, there’s no valve cover in a BMW sense of this word. It’s an integrated valve cover/cam girdle, if it starts leaking, then you’ll have to mess with locking the camshaft. While easy for a seasoned mechanic, a lot more intimidating for an average diyer. I could go on, but I wouldn’t get so excited about this cars so quickly.

[@NathansBMWWorkshop]

lol these are not hard jobs, remember all the past cars i had and past videos, not much scares me anymore

[@fastboatster]

@@NathansBMWWorkshop yes, but the point is that it WILL be intimidating for a more novice person. I mean, it’s cool but getting some brackets holding some rubber air guides in the way of ac lines so that you can’t pull the evaporator out of the brackets on the radiator without disconnecting the lines is not stupid. It’s actually very smart and malicious, and that’s kind of quintessential VW group. 2009 - lines allow to unclip it, but 2010 the manual says “ac lines have been improved”, need to disconnect to replace the radiator. And it’s not just the labor, parts such as control arms, engine mounts are quite a lot more expensive. No, it’s just not the same as my e90 where I was able to pull the radiator out on the side of the street without jacking the car up or replace the belt in 15 mins doing it first time ever and in the parts store parking lot. Another thing is that they have timing chain issues and oil consumption, and all this is just too much to bother for a car which is not better driving and engaging as an rwd e90

[@Tweakin]

@@fastboatsterI’m fairly novice.. oil change here, brake job there. This legitimately looks as simple as it gets tbh especially considering

[@fastboatster]

@@Tweakin yeah, so is oil change on many bmws or brake jobs. Speaking of the brake jobs, b8s already have an electric parking brake, need a diag tool or need to apply some voltage to the parking brake motor to replace the rear pads without breaking anything. 3 series up to g series still have normal parking brake. Bottom line, own and drive the car you like but be aware that Audi is not really easier than BMW

[@klubstompers]

You could tell injector #1 was stuck open, because when you removed the injectors, fuel was leaking out of it. This wont happen, unless the injector is open.

[@vexican8132]

I'm having this EXACT issue, and i've been chasing this problem everywhere. Could you tell me what you did to remedy the problem?

[@NathansBMWWorkshop]

Fuel injectors

[@isleseayou]

If you’ve already replaced your coils,plugs and injectors and still having issues, replace your turbocharger wastegate. Like $50 on Amazon. I did this before injectors and it solved my issue.

[@ddubz6356]

[@gerardogarcia-et2pb]

You are good in all the explanation clear talk.

[@fastboatster]

Just wait till you get to do a suspension refresh, you might be having a lot of fun with upper control arm knuckle pinch bolt.

[@Jacob-ug5hy]

Yeah I had to replace my whole spindal on that one. Put anti seize on the bolt and has came off smooth so far

[@robertoalvarez7960]

Cake compared to this

[@grantbradley5084]

My 2012 A4 2.0 had a misfire. The motor was emitting a knocking noise from the front of the motor. Mechanic replaced the rocker arms and lifters. Knocking sound still there. After scoping, was determined cylinder #1 is scored, requiring replacement of the motor. Rings, pistons and timing chain replaced at 57K. Engine failure at 67k. New long block installed, issue addressed.

[@uptownclarkson6662]

Does your car run good after the engine replacement? I have the same problem but don’t know if I want to waste the money to fix it

[@Lovely_planet]

"ECS Junk" i lost it hahaha

[@Mattmazz77]

Yeah you're right about ecs tuning some of their own stuff is not quality. That fitting for the boost gauge or controller was causing a vacuum leak. Plus the boost gauge I got from them came with shit vacuum lines, the little adapter that converts analog boost to a digital signal is straight garbage!!!!!

[@vexican8132]

What was the issue and the fix?

[@robertoalvarez7960]

Very thorough thank you. Glad to be on board.

[@ShowMeWhatINeedToKnow]

How does he drive at night?

[@jessesward9429]

Can a stuck injector hydrolock a cylinder?

[@andyb6851]

yes

[@timgilman2495]

If you cycle the key enough times to put "that much" fuel into the cylinder without turning the engine over, yes. Expect the engine oil to be contaminated by raw fuel as well.

[@GeorgeAusters]

I would have put the car back to standard, could be the tune that is over fuelling

[@EXOVCDS]

Lack of residual pressure in the fuel rail is to be expected with a leaky injector, no? You seemed surprised about that.

[@robertoalvarez7960]

He did great explaining it as a person that just started or is learning don’t be rude man

[@jordanacohen9555]

Nathan, get yourself a Milwaukee Electric Hand Ratchet.

[@ericbloomquist9040]

Aftermarket Boost Controller?

[@stefanczechorskidds8435]

With the injectors plugged in electrically and fuel line connected and the manifold pulled back as you had it, it would have been informative to see what happened when you turned the key to ON. Any good injectors would not spray or shouldn't spray fuel . Definitely have a rag over number one suspicious injector!

[@410kane]

Had the same problem. Cylinder 1 misfire. I changed the plugs no result. Switched coil pack between 1 and 2 cylinder no result. I'm assuming it's an injector clog

[@Aikorslickbacks]

It’s a little low on coolant too

[@gregcowart8229]

Nate with all do respect my n54 motor is a hell of lot easier to pull injectors than that one no disrespect dude

[@NathansBMWWorkshop]

But then you have to code the New bmw injectors and they are not $200 for new ones

[@fastboatster]

Coding the injectors is not a problem at all, everyone watching this or any kind of bmw channels knows how to get INPA/ISTA and code those injectors in. As for the N54 injector prices, they got jacked way up not in the least because all the kids like the one with this VW started to buy them because “it’s a German 2jz” and all the KZbin hype.

[@NathansBMWWorkshop]

@@fastboatster ah yes but you still have to code them and most people cannot do that and most shops won’t do that , remember this is more comparable to a n20 engine , and no electric water pump on this one , and rainwater don’t back up and flood the ecu either , I have had a lot of Audi’s in the past , a6 and TT’s ,all cars have their issues and some are just more reliable than others depending what engine , at 100k miles they all need major service which most of them never get regardless of brand

[@fastboatster]

@@NathansBMWWorkshop yeah, I guess we can argue for a long time about this and not come to any agreement. But I just want to say that having both one b8 chassis car (s4) and one e90 328i and talking/reading the forums for either platforms, I’m not so hot on the b8 platform anymore. B8 came in in 2007 in Europe so really similar timeframe to e90, and while Bmw gave us pretty much the last of its kind NA I-6, VW/Audi came with 2.0t econobox engine. And for the turbos, n54 is a class or 2 above 2.0t and really compares to 3.0tfsi in a much more expensive and also somewhat troublesome b8 s4. Anyways, the conclusion is that it’s great to have different cars on the channel and perhaps it takes time to really gauge what the car really is.
