In serious need of technical expertise

#1

Good news is that I finally remedied my O2 sensor faults after replacing all of them with new ones. However, I now having some serious other issues. My car battery finally died while I was on leave for two weeks. We first tried to jump it which lead to real bad misfiring and stalling conditions. Had the battery checked, and it cam up 6 volts. Replaced it, and have come to the conclusion that it was probably still the original. Started car, and it basically ran like shit. Ran VAGCOM and it detected multiple misfire on cylinder 5. Decided to replaced the spark plugs since I am betting they are p’bly original, too. Car still had issues under acceleration. Ran VAGCOM again, and the multiple misfire had moved from cylinder 5 to cylinder 8. This led me to decide to swap the coils. Guess what? Still having issues under acceleration. Ran VAGCOM again and now the misfire is on cylinder 4. I have checked the fuses in the door and near the ECU under the hood and they look fine. Also, each time has thrown the CEL, of course, going from flashing to solid. I also now have some other low voltage codes around the interior of the car. I will post the readouts from VAGCOM in order from oldest to newest. Also, only faults that occur, not all addresses.

Are you clearing all of you codes each time you change something?

Why do you still have O2 codes?

Did you ask JHM if the plugs were replaced with the kit? I doubt they would have left original plugs in and I also doubt the plugs used with the supercharger are the same as OEM.

#3

Yes, I have cleared the codes each time. Not getting O2 codes anymore, and the plugs were fouled when I examined them.

#4

^^ 100% know they’re not the same oem plugs.

#5

Regardless, changing the plugs did nothing

#6

Plugs are not stock, because when they install our SC kit they use diferent plugs for it!

#7

The plugs were still fouled, and changing them still didn’t solve the problem. This isn’t supposed to turn into a conversation regarding whether or not JHM changed the plugs. Nothing inside the scope of normal maintenance or recommended items has solved the problem. Can we please stay on topic, because this is really frustrating and I want the issue resolved.

#8

Clear everything again.

Make sure all of your coilpack connectors are seated properly.

If and when you get another code then update this thread. I know you are trying to sort your car out, but you are changing too much shit at once and you’re going to end up chasing your tail for no reason.

You left and the car had no issues, right?
Who did the O2 sensors and when? Did the problems arise right after this or was it a little while?
Also the type of plug you installed could potentially cause issues, what plugs did you install?

#9

There are tons of little things that people screw up, I’m not saying you screwed anything up but check the little simple things like connectors before you continue throwing parts at the car.

#10

This has not been done all at once. I returned on the 5th of June. That is when I jumped the car. The next day is when I swapped the battery. This is when I got the first code. Cleared it and it came back to verify. Monday, I changed the O2 sensors (which did solve the O2 issues). However, this didn’t solve the misfire. On Tuesday, I swapped the plugs. That is when the fault shifted from Cylinder 5 to 8. Bought coils on Wednesday, but didn’t install them until this morning. Fault shifted again from cylinder 8 to 4. Each time I have ran VAGCOM a minimum of twice to both clear and verify the faults.

#11

My fear is that there was a surge caused by the jump.

#12

Okay Marcus, slow down man. It appears that you have sorted out the issues for the battery and O2 sensors. Lets focus on the misfires.

The JHM SC uses colder range spark plugs than stock on the S4s so it is a good assumption that they do something similar on the RS4s too. If you put in stock spark plugs on a supercharged car then you will likely have misfires. So call up JHM and see which spark plugs that they run for the SC kit. I know for the SCed S4s that JHM uses these spark plugs: https://jhmotorsports.com/shop/catalog/spark-plug-bosch-tri-electrode-bosch-heat-range-for-18t-20t-27t-p-687.html?cPath=21_56_60_100_132

I have had to replace mine a few times because they were fouled. But I have other issues like leaking valve stem seals.

#13

Marcus

When the 02s…go you can expect the car to run rich and lower the max rpm. So depending on all the things it’s normal for the car to not be able to get the plugs upto temp to clean them off. You do have different needs for plugs with a supercharger so there were most likely different plugs.

You have open circuit codes so that says maybe no good connections. Like Euro said. I would get the right plugs and swap them in after that see how it goes and what codes if any come back. The misfire seems to be moving around so there doesn’t seem to be any strong sign of issues other then just little bugs from working on the car.

#14

just put back in the same plug u took out. jhm most definitely replaced them. they are bosch rs… something or other. I just through the boxes out so I cant remember exactly but it will say on your old plugs.

how are your high pressure fuel pumps? does it misfire just cruising or when on the throttle?

#15

Why is Marcus not listening?

Why is Marcus on audizoo lol

Saki, shut up. I am listening. I posted at the same time on there with the same question in case someone there would have some insight. Do you have any good ideas as to what it could be??? I have already done everything that has been suggested which is why I am asking the question to begin with. Like I said already, the pugs were fouled when I inspected them. This was most likely due to the the horrible way in which the initial jump caused the car to misfire and dies over and over for the 20 minutes I was trying to get it going. The HPFPs are fine, but I can’t upgrade with my new internals from JHM until they have completed the tune.

Because AZ has a wealth of knowledge… ::slight_smile:

I’ll summarize.

He had a bad O2 sensor, which could have been also causing misfires or rough running…Marcus other things can affect the cars ignition outside of plugs and coilpacks.

It doesn’t look like he ever replaced the O2s and then cleared the codes and ran another scan. He instead believed the misfires with a bad O2 meant he also needed to change the plugs. He immediately decided to replace all of the plugs because of a random misfire (because they were probably original) Which I and many other HIGHLY DOUBT.

What spark plugs did he use? No one fucking knows because he just wants to argue that it wasn’t the plugs because he replaced them and it did nothing. Marcus if you put OEM plugs back in the car…it will probably RUN LIKE SHIT! Because you should not be using an NA plug for a boosted application. This is the reason why plug have heat ranges!

After he replaced the plugs he did another Scan…I can almost tell you 100% that the damn coilpack connector was not seated all the way. You don’t randomly get an open circuit when you didn’t have one before unless you didn’t connect the coilpack all the way. SO instead of checking over his work, he bought all new coilpacks.

Then he replaced all the coils and he has an open circuit on cylinder 4…go figure

*PUT the right damn plugs in the car
**make sure all of your coilpack connectors are seated
***clear all of your codes, do a TB adaption and drive your car

This shit is never rocket science, it’s logical troubleshooting, which like I said in my first or second post you are not very good at. You can’t just throw parts at a car when you see a problem. You may have just wasted time and money on parts because you didn’t seat a connector properly. but if you don’t want to listen to help after YOU ask for it, then have fun figuring out your problems with the members of AZ.

5 times people have asked if you REPLACED the spark plugs with new ones and if so, which new ones. You keep not answering the question.

Now you tell me to shut up? Nice.

Euroswagr summed up quite nicely why I asked why you weren’t listening.

But hey may badbooboo and Jared on audizoo will point you in the right direction. Probably a surge that caused it as Jared suggested lol

Are you related to skywagon mk1?

Marcus, what fucking plugs are in the car? I dont’ care if the ones you looked at were fouled. Did you put OEM plugs back in the car.

If so, take them out and put the RIGHT ones in it. Then make sure all of your coilpacks are connected properly.

Clear all codes and drive the car.

You may think we are insulting your intelligence by saying “check the connectors” but we have probably all missed stuff like this and sometimes the coilpack connectors do not seat properly.

The only advice about spark plugs was to replace with the old ones, which I will not do. I won’t put fouled plugs back in. I also have replaced all of the O2 sensors which is why there are no longer any DTCs related to the O2 sensors. I have ran the gamut and checked every fucking seal on every fucking coil connector. The fact of the matter is every time I did a change it moved the fault to a separate cylinder. The battery jump caused the initial fault on cylinder 5, changing the plugs moved it to 8, and the coil pack change moved it to 4. You are also wrong, this has been nothing but an insult on my intelligence. You don’t think that JHM and I haven’t been talking through this whole process? Sorry, that they don’t work on the weekend when this last stitch effort fell through.
