good looking out Adam! Hopefully the IE's and 034's of the world can take notice and not chalk these issues up as isolated incidents.

Wise idea!

[@gges1605]

This is what always scared me about modifying my s5 I did a remap on my transit custom a few years ago and it went wrong a few months later and blew the turbo oil seals and caused engine runaway. The s5 although petrol not diesel is considerably more expensive and a lot more expensive to fix. I have an extended warranty on the audi that cost a few hundred pounds at the time that would be void if the car was modified perhaps after that runs out I may look into stage 1 but I don't think I would risk going beyond that figure you are stressing engine far enough at that.

[@DimaH_S4]

Makes me wanna go do a full test on my car 😅 From compression test to even maybe getting injectors inspected also. Car at about 109k KM on it and been tuned since about 20/30k KM sadly did have the rocker arm failure 😢

[@VancityAudi]

Sadly no, I suffered another catastrophic failure the following week, which I'll be sharing on my channel this week.

[@nates2243]

If you’re getting oil past the rings on cyl 1, maybe a ring land is cracked from that event that broke the electrode letting that oil pass by. Often times when scoping the piston, it can look fine from the top but have damage to the ring land.

[@VancityAudi]

Ya, that's what I'm thinking too.

[@FastLifeVlog]

[@accordv6er]

@@FastLifeVlog *how* common... I'm looking very seriously at an SQ5 but I'm not so sure, just not a lot of miles on them yet. B58 still too pricey, and N55 is a known, but the chassis don't do it for me

[@SteremyJeele]

@@accordv6er The EA839 platform is 5 years old now, plenty of cars above 100k miles, and major issues/failures seem to be a rarity. Even more rare in folks who are not beating the absolute death out of their cars. If your plan is to buy an SQ5 as a daily, and occasionally rip it on a backroad, there's no real reason not to. I bought a used '18 S5 this year, and apart from moving the maintenance schedule up 10k (to account for unknown maintenance from previous owners,) I don't have any real concerns about this thing. If your plan is to take it to stage 3+ and hit the track constantly, just make sure you get one with low mileage and do all the preventative work up-front (intercooler, injectors, etc.) I would comfortably call Adam a pioneer in the platform, and he has used the hell out of his machine, upgraded it beyond what 99.9% of owners have, and only just now run into a major concern. That's pretty good for any modern platform, honestly.

[@WeI3I3y]

B8.5 stick with it and hold onto your baby. While B9 is faster with ease Hmmmm...Weigh your options. I love both and can only make a decision due to the work that Vancity Audi has worked so hard for us all! I'm just saying me personally will not switch platforms to gain a tad increase for a 20k difference at current prices. Thanks Vancity Audi for the hard work you put in to allow us to make important financial decisions! You are a true hero and saving so many people the good and the bad fortune of owning a special vehicle.

[@VancityAudi]

Thank you for the kind words. Even with these problems, I'd still have a B9 any day of the week over a B8.5. They are so much more enjoyable to drive. Plus, I know of plenty of B8 owners that have lost motors to other failures. I didn't push my B8 any harder than a full bolt on setup, and that's probably a reason my motor didn't fail on that platform.

[@WeI3I3y]

@@VancityAudi I have yet to drive a B9 but I do take your word for it. I've watched all of your videos and I know you love and prefer the B9. I do love my B8.5 tho and drive her every day and so far I'm very happy with it with no plans to change it up. I don't plan to take my car anything past what you did with your B8 but so far so good with IE stage 2. I have a bit more to do to get to where you were on the B8 but I feel like that's still safe enough for what you get out of it. Owning the car at 40k miles, purchased at 9k is a dream for me so I'm super happy. Before it was turbo charging built Honda motors, still have my prelude from high school lol...

I sold my 19 s5 8 month ago because of similar issues. I was on pure750 for more than a year and first 6 month were trouble free. Then had a failed stock injector, month later car would start misfire on 3 cylinders. Spark plugs were completely black when i pulled them out, replaced them with aftermarket ones. Nothing changed, later i noticed oil in my cylinders. Decided to sell it before ill need a new angine and transmission. Transmission wouldn't shift from 3rd to 4th sometimes in auto mode, and then throw me an transmission overheat. It was my weekend car and loved to drive it, but going stage 3 we gotta know the risk of it. Good luck with your s4 and i hope nothing major is wrong with it.

[@VancityAudi]

Thank you and I'm sorry to hear you had so many difficulties with yours!

[@awhs5435]

Similar situation here, sold my 18 B9 S4 around 8-9 months ago, turbo failure and a few other things, the price they wanted to repair just wasn't worth it, they only value these cars at like $40k or so anyways and when repairs are like $10-12k, it's better to just walk away then to spend like 20% of the cars value on repairs.

[@durksgarage]

My b9 with 51k miles just blew up. Blew up a spark plug. One cyl. at 40psi and scoring on cylinders. IE tune stage 2. Downpipe, intercooler, intake. Sucks

[@SynysterJesus]

when I was at vw we have seen a few none tuned gti's and golf r's with the same issues with the spark plugs, didn't find any cylinder or piston damage. we are thinking that the top of the spark plug got way to hot, they had oem spark plugs and ignition coils. My QTM and vw tech line were puzzled. the vehicle's had more than 60k miles on them too. Maybe it was a weak batch of spark plugs out there.

[@VancityAudi]

Could be!

[@mstauss2566]

I was having weird up tics in rpm’s in first when coming to an stop and then got a bank 1 lean check engine light. Carter modified the tune and it seems to be running a hell of a lot better but now I’m worried about it after seeing this.

[@VancityAudi]

Just do a quick check on all your spark plugs. Glad Carter was able to help you out.

[@Apex60feet]

Can you inspect cylinder 1 from behind? I know the Porsche community often check for bore scoring from the sump because this is where it start and you may not see it from the sparkplug hole. Bore scoring is also a cause for higher oil consumption.

[@VancityAudi]

I suspect we'll do something like that when we decide to take the motor apart.

[@SouthdownGarage]

I truly hope you can find a "a cost effective" solution that fits what you're looking for. After I saw your video I dialed back all of my cars to 93 octane tunes.

[@salninethousand2496]

To me it looks like the plug tip was consumed (i.e., burned away) rather than broken off. Without compression (due to non-firing cylinder) the rings won't seal properly, letting some oil blow by. That's probably the best case scenario. Let's hope it was a loose spark plug or some other easy fix!

[@VancityAudi]

Any idea why my plug would be turning black still then if there was no damage and the spark plug was consumed?

[@salninethousand2496]

@@VancityAudi Not an expert, but have screwed up and owned plenty of bum engines in the past: Oil low by on a plug thick and crusty and happens almost immediately. The first replacement plug (6:48) has a thin matte coating as if though it's running cool or the A/F was too rich. The second replacement plug (7:38) looks fine to me. The top two rings are compression rings and the oil control rings sit further down on the piston. So damaging only the oil control ring(s) and not the compression ring(s) seems unlikely (that static compression is within 10% across all cylinders says the compression rings are likely OK). What happened to kick this all off? Might never know and there might have been multiple failures. If it were me I'd redo the static compression test and then do the leak down test. If both are within factory spec for all cylinders I'd continue to check the plug every few days of normal driving.

I've been daily driving it since the failure. I've downgraded to the 91 octane tune. Still oil in the cylinder. Car has trouble starting sometimes. I haven't put more than 10lbs of boost through it. Drives totally normal though. Once my RS3 is fixed and on the track we'll look into fixing the B9.

[@spacecased91]

What fuel were you running when this happened?

[@VancityAudi]

E70

[@spacecased91]

Appreciate the quick reply. Guessing you left this platform which is unfortunate as I enjoyed your vids. enjoy the MK8. Such a fun, tuner friendly platform.

[@VancityAudi]

@@spacecased91 I haven't left. I've shared in multiple social media posts that were repairing this car, will run a 9 and then sell it.

[@hittingreens5646]

I traded my B9 in. Was eating metal from the cam sprockets. If you're stage 3 you're just asking for problems.

[@VancityAudi]

Sorry to hear that!

[@rafaelbatu7525]

Hey Adam, Have you ever heard the story of the fake chinese NGK plugs that look almost identical to the real ones? Even the boxes are almost identical

[@VancityAudi]

I have! I've seen people buy plugs like that from Amazon and Ebay. Luckily, we buy all of our parts through dealers and well-known automotive suppliers, so we know that wasn't the issue.

[@MikeFico998]

Yeah man you fried a ring

[@VancityAudi]

That's my guess too

[@WhereBrentWent]

I’ve heard from reputable engine builders that excessive cylinder pressures can cause hyper-wear on spark plug electrodes. It very well may have electrically burnt to that length over the course of thousands of ignition events at high rpms.

[@VancityAudi]

It broke off and damaged the rings.

[@Cuprone]

​@@VancityAudiYou have finally sold the S4 right? Did you repair the engine or how did you make the sale? thank you 😢

[@VancityAudi]

​@Cuprone if either of those things took place you would have heard about it on the channel. We've found a replacement engine and will be doing the swap next week!

[@Cuprone]

@@VancityAudi good luck and thanks for answering!!!!

[@VancityAudi]

Thanks and no problemo

[@jimmymcgoo8641]

Its the E fuel wrecking the injectors and then obviously resulting in engine damage.

[@VancityAudi]

Considering we've seen multiple failures of the exact same nature running pump gas, I'd have to disagree.

[@jimmymcgoo8641]

What Ethanol content does your pump fuel have ?

[@francoleon91]

Bummer dude, always scary modifying your daily to this certain extent.

[@VancityAudi]

Ya, it's always a risk, no doubt. I'm just very surprised this is happening to so many other people as well.

[@4TKRACE]

dang detonation! need just betta software

[@VancityAudi]

As I mentioned in the video, we've seen it in stock cars, Stage 1 cars, and Stage 3 cars. It has nothing to do with the software.

[@4TKRACE]

@@VancityAudi too much ignition timing, also ignition retardation table too much recalibrated, so there is 0 knock correction, but there is knock.

[@VancityAudi]

@4TK RACE guess you'll need to speak to Audi about their calibrations, seeing as we've seen this issue on stock B9's as well.

[@evorealtime]

Detonation is always top of the list for most engine damage. That a part can fail stock at a different rate does not change that.

[@johnsharp5753]

We can test your injectors at 300psi (with water, not fuel), but my company is in Texas. Shoot me a message if you are interested.

[@VancityAudi]

Thank you very much for the offer. Would the flow rates be affected by running water rather than fuel? Are these injectors meant to have water flowing through them?

[@johnsharp5753]

@@VancityAudi Water and fuel have similar enough density and viscosity so I wouldn't expect flow to be affected. I'm sure it isn't recommended by the manufacturer but as long as there is plenty of time to dry before placing them back into service.

[@tanveersekhon7795]

Its a love hate relationship with the b9’s :(

[@VancityAudi]

Agreed

[@rafaelbatu7525]

I didnt even watch the video but the thumbnail dont look goodd 😮

[@AD-xq4ho]

If watching this guy taught me it’s to not buy an Audi 😭😭😂

[@VancityAudi]

I'd think the same thing! lol

[@czrtsunami]

So keep my b9 s4 stock then yeah 😂

[@VancityAudi]

As I mentioned in the video, we've had a completely stock B9 S4 fail in the exact same way.

[@jonhaze7537]

DAZA ftw

[@VancityAudi]

LMAO. You won't be saying that when you see one of my upcoming videos.

[@arturasbalnys1364]

Looks like motor kaput...🙄

[@nolanpeters5462]

LOL

[@VancityAudi]

What's so funny? Don't think I made one joke in this entire video. If anything, it was boring and not funny.
