After what felt like an eternity of having non-stop misfires and breaking up during WOT runs in my 2012 Audi S4, we FINALLY figured it out!!! Quite a few people DM'd me on Instagram, sent me a message via Facebook Messenger or commented on one of my previous RU-vid video stating that they are or were experiencing the exact same issues that I had. With any luck this video can help them diagnose their issues and help them get the most out of their Audi B8 S4 once again.

I had a similar issue with my modified 1987 Buick Grand National. Despite a larger FP and injectors, I had to "hotwire" the FP to the alternator directly to get enough power to it. When you said the actual issue I was like "holy shit no way" haha, but it makes total sense. Can't wait to see that first 10.8 run.

Love the video as always. These are my reference half to time for when logging my own car by chance is a stg 1 non pulley tuned car LPFP also supossed to be 4500 or above ? I also have the brisk plugs I switched them out for NGK 034 said my car would be fine on those but it was not running good I noticed a huge difference when I switched back to NGK

@VancityAudi 2 года назад

From what I've been told 4500hpa is the absolute lowest you should see. From my experience though you want it closer to 5000hpa at the lowest.

@oemtam 2 года назад

Very interesting and really supports your data log anything impacted by the component you change out, a new added to my list voltage. Kind of interested in Braille saying that battery would support the car; was the amp rating too low on the battery? Their statement of support really caused you a boat load of time and cash, did you reach out to them and let them know your results?

@VancityAudi 2 года назад

The battery failed originally in my 2018 Audi RS3. There is a very specific problem in those cars where they have the inability to use lithium batteries. I think perhaps that may have hurt the battery in the first place. Even though it showed a full state of charge once I juiced it up again, maybe it wasn't able to be charged by the alternator properly. I haven't reached out to Braille again, but I will be.

Running into similiar issues on my SQ5. Thought it was my cats failing so I went test pipes. Still getting it, only thing left to play with is battery. Turns out it is the OEM battery from 2014. Sucks I found out after replacing the SC cores, carbon cleaning, cleaning injectors, and installing test pipes.

@VancityAudi 2 года назад

@Mazzerants 2 года назад

@@VancityAudi Think I figured out what the underlying issue was. Seems to be more prevalent on IE tuned 3.0T's vs 034 but it is the LPFP not being able to supply enough fuel when near and at e40. I was able to literally drop in (after finagling the siphon tube) a RS7 bottom half of the the LPFP. Part number is 4G0919051L. Motor finally pulls over 6k without fuel cut and misfire. Sounds healthier too and drops flames a lot more now.

@justinspoon5408 2 года назад

Got a P0089 code tonight, have the upgraded fuel pump on my b8.5 and running E40 integrated tune…. That code brings up fuel pressure regulator and I lost rail pressure. Could that be the hpfp fuel sensor, or do you think my upgraded pump is already dead? Thanks in advance

@VancityAudi 2 года назад

Sadly I'm of no help to you there. I never experienced that code and was using an OEM pump. Not sure what your problem may be. Sorry.

@GTOworshiper 2 года назад

I had the same problem in my RS3 when running that exact braille battery. Since it's lithium it has a much lower resistance compared to an OE style battery so the car sees it as fully charged when driving around. To "fix" the issue I unplugged the connector on the ground strap that the car uses to monitor the discharge rate of the battery. Since the car can no longer see what the battery state of charge is it defaults to juicing the battery at about 14.5V when driving now Could put that braille battery back into your S4 with the connector unplugged and see if it allows you to run the lighter battery and not have the same voltage issue? Love the content!!

@VancityAudi 2 года назад

I like how you put fix in quotations. I don't see that as a fix. I see that as a work around that will kill the longevity of your battery. I as well did that and will be going over what else we did in my RS3 in a future video.

@GTOworshiper 2 года назад

@@VancityAudi yeah, it's definitely not a solution. Braille was saying by putting a resistor in line on the 5v signal could work but haven't had time to figure that out. Definitely look forward to seeing what's next for your RS3

Sadly, no. I suspect if it is happening in only one cylinder, something more serious is happening. Sorry

@fshah4802 Год назад

@Vancity Audi i have a feeling it is carbon build up. The car runs normal no misfire only if i go above 4k rmp with wot then it throws the code. Also if it was cylinder compression problem then it should throw error all the time correct? Ps plugs and coil packs are new

@wgfvideos3768 2 года назад

😄 I got a b7 S4 it had a 7 year old battery just replaced last month and it can be significantly noticeable. These cars have a advanced engine management systems and sadly they don’t do good jobs telling you it’s a battery because the ECU thinks it’s ignition related. most cases you get random codes or none at all until you test your battery and see the volts are below 14-13 while idle. So it was the ECU power supply below threshold. How can the ecu identify this?The cars brain needed a coffee that day bud;)

@JDFelda 2 года назад

Anyone else hear the fuel pump start priming right when he started talking about how good the fuel pressure was after swapping batteries?

@skyhookpro 2 года назад

Adam you do a great research in a hard way, but you need someone to have access data (like audi tech on the dealer)...Im porsche tech and I follow you about yr ago...and I see that you need this info for proper diag..e.g low fuel pump pressure...we know that you audi does required between 4 to 6 bar and is controlled pwm by dme and or fuel pump control unit...If you need documentation or any audi info let me know i can help you....i work in a multi dealer in south fl...also the electrical system are not full capable on lithium bat...the system is design and optimized to work with agm batterys even the system have the option for lithium (gateway programing)...but people around internet misinformation lead to wrong doing in VW group car...like I said if you need any documentation just let me know im willing to help you out...

@VancityAudi 2 года назад

Your data wouldn't have helped me at all sadly. You know it "required between 4 to 6 bar"... It has never dropped below 4 bar throughout this entire process. The electrical systems aren't supposed to be able to properly use lithium batteries in a bunch of VW's and Audi's yet people do so regularly without issue. I very much appreciate the offer of the data you have at your disposal though.
