Audi S4, Q5, & Q7 Ignition Coil & Spark Plug Replacement DIY (B8/B8.5 3.0t V6 Supercharged Engine)

► The ignition coils on your Audi S4, S5, Q5, or Q7 are responsible for providing voltage to support the spark needed to trigger combustion. Your car might not display a check engine code when your ignition coils are malfunctioning, so it is up to you to diagnose the problem. We recommend replacing ignition coils on your Audi B8/B8.5 every 100,000-miles for peace of mind and optimal performance.
Aaron Davis, our Audi Catalog Manager, shows you how easy it is to replace the ignition coils and spark plugs on a 2013 B8.5 Audi S4 with the 3.0t V6 Supercharged Engine.
Common Symptoms of Ignition Coil Failure:
Misfiring of engine
Reduced engine performance
Trouble starting the vehicle
Reduced fuel economy
Engine backfiring
Check engine codes

A good tip I discovered for removing the coils is to get a plastic tie wrap and create a loop, then hook it around the head of the coil and pull upwards. Dead easy and saves any risk of damaging the alloy engine.

[@fcpeuro]

Yes, great tip!

[@jermainejames3333]

I’ve watched a ton of videos on how to do this process but this is by far the best .

[@AdamHowardTravelerdawg]

Thank you so much for this demonstration. These German vehicles are intimidating for me but now I am confident I can easily perform my maintenance.

[@fcpeuro]

You're very welcome, Adam! Really happy to hear we can help inspire confidence when it comes to DIY maintenance!

[@AtypicalDriver]

Very helpful, thanks! Just did this job on my wife's Q5, thought there would be enough remove to avoid removing the coolant tank or airbox but nope...you definitely still need to. Man getting those ignition coils off is a PITA!

[@fcpeuro]

Glad it helped a bit, nice work!

[@petereacmen716]

FYI Factory Service Manual says torque for spark plugs on the Q5 3.0T is 30Nm.

[@erinrobson]

I also recommend anti seize and dielectric grease on the plugs. Nice video.

[@twn2rbo]

Helpful vid. I just had a misfire in cyl 4, IE tunes app showed me. I’m going to swap coil packs first and track down what’s going on. I can’t wait to get back to back 7.200 rpm shifts!

[@willspy4u]

Very much appreciate your effort on this video! You made it understandable and look almost easy. I'd say: if there's a way to full remove the coolant res; then that would make it even more awesome! Maybe anti-seize on the plugs; but that's about the only thing I'd add. I'm also interested in general 'cost range' of the coil pack & plugs.

[@jonmunroe4064]

Not sure if antiseize is the correct product for this application; I think dielectric grease should do the trick - I made the mistake of wiping the factory-applied dielectric grease from the tips of the coils I installed 5 yrs ago. When I went to change coils and plugs again, every single coil had corroded to the ceramic on the spark plug. Was a pain to get each one out without taking it in - had to use long pliers and a long pick set. If this happens to you be sure to either blow out or vacuum out the spark plug hole before removing the plug.

Can you guys show or post how to deal with sticky coil packs? what to do when one gets really stuck. Also mention dialectric grease placement, any on the rubber boot top of the coil pack.... Any impressions on Bremi/Denso coil packs over VW/Audi OEM?

Let me know if you're interested- and whether or not to email you the link or post it in a comment for all to peruse. I had no idea you guys even existed until I owned this E39.

[@istillplaywithcars]

Nice job! 👍🏻👍🏻👍🏻

[@treatordie]

I learn a by my mistake, i broke those hose while operating this spark plug in, it's okay to open those hose and put the tank down on the floor...

Do u need to unplug the battery? For safety concerns or Audi ecu?

Was doing this and seen a little black gasket inside the spark plug hole ripped up . Is there a gasket supposed to be in the hole?

[@nonamenoname5518]

How is the cylinder arranged with me is the 5 Defekt

[@sarcastixx74]

Well demonstrated as always! Just a thought, can these not be replaced without removing the intake or moving the coolant expansion tank? I appreciate that it makes for easier access but is it mandatory? Thanks for all your S4 B8 vids, I've just recently acquired mine and due to your uploads the maintenance work looks much easier already. Keep up the good work!

[@fcpeuro]

You might be able to, but there is definitely more access with the intake and coolant expansion tank out of the way.

[@oakleafs30]

It’s worth the extra steps to remove it rather than try to fight with the limited space the whole time

When will VCG diy video be up?

[@mastalee1776]

Definitely nice and detailed. Thanks fpc euro

[@fcpeuro]

Our pleasure!

[@jerryx2000]

do theses red ones give more torque below 3k rpm?

[@fcpeuro]

Hi Jeremy, the red coils are a newer updated design, less prone to failing, especially on a tuned vehicle.

[@vinnybionic8651]

Does the same torque specs work for a 2010 s5 v8?

[@jamar8887]

Which is cylinder 3 I got p0303 code

[@benisosa2752]

2014 Audi A6 best spark plug 🔌?

[@robertdaone]

Do you need to adapt the new coils with the cars computer, sort of like when you install a new battery?

[@fcpeuro]

Hi Robert, no need to do so. If you have a prior error code, you will want to clear that with a scanner first.

[@nevaehlavoie2286]

Would you recommend ngk over bosch and why?

[@stefdriver]

Yes mainly because NGK is the OEM for VW Audi and the Iridium IX series seems to have the most features and solid engineering data to back it up.

[@nicholasmofidi2359]

I see different views on the spark plug torque, Deutsche auto parts says 28nm plus 90 degrees and you guys says 35nm? Does it differ per spark plug brand?

[@stefdriver]

It could differ by brand. Some plugs like NGK have an integrated crush washer.

[@bsears85]

Does the battery need to be disconnected for this job?

[@fcpeuro]

Not mandatory, but certainly does not help, especially if this is your first time doing this DIY.

[@donttrip1444]

Which coils do you use?

[@Halidaye]

Hey I did have a question I just changed my coils and plugs after having a misfire in cylinder #4 and I still have the code in my reader. No check engine sign and I do not hear any misfires when I turn the car on. Not sure what to do other than just maybe look inside where the plug sits?

[@fcpeuro]

Iowa have you cleared your codes, and driven the car much since replacing?

[@Halidaye]

@@fcpeuro I didn’t drive it yet however I will today but I have tried to erase the code

[@fearz4182]

Is is necessary to do a 90 degree turn after torquing the spark plugs ?

[@European_carclub]

No just torque to spec which should be around 30nm. First hand thread it before you torque it so you don't strip the spark plugs.

[@roskataqv]

Is there a torque difference depending on if the engine is hot/warm or cold for the plugs?

[@Bytrl]

Yeah, absolutely man. Its 1 slow ugha duggah hot, or 2 mild ugha duggahs cold

[@arthurbryant3193]

Hey Aaron, I have a 2013 Q7 Premium Plus and I'm trying to remove the coils in cylinders 2 and 3, but I'm having the toughest time getting them out. Any suggestions?

[@Alonso_99]

Since they already come pre gapped, how much gap?

[@stefdriver]

For the supercharged engine I recommend no more than .028 gap. The gap should be even smaller if you’re boosted and running cooler plugs. The plugs usually come with a bit larger gap like .03+ so I disagree that they are pre gapped for all applications.

[@a1b2c3787]

How much a mechanic charge to do this?

[@442caleb]

If i get just an iridium spark plug from a local autoparts store, would this be a problem? Or should I do NGK?

[@fcpeuro]

We highly recommend NGK.

[@stefdriver]

NGK is OEM, don’t fuck around.

[@oujee1988]

I wonder why the ngk: bkr7eix plugs wont fit ?

[@stefdriver]

You need 8eix for the stock supercharged engine or 9eix if your ECU is tuned (80+ hp).

I figure i’d add because the actual spec is not listed here, 0.028” is the correct measurement. I just did this today and indeed the plugs came gapped correctly, but I checked all 6 anyway.
