Audi B8 Spark Plug Replacement - Misfire? Fix it! (A4, A5, TT, Q3)

[@Mayhemman33]

There is a weird part that the torx screw is attached to the what is that. During the install I crushed it and white plastic went all over. How bad did I mess up. Thanks for the video. Lots of help.

[@bos6782]

The instruction was very helpful and to the point. I have an 2011 A5 and the error code for me is P0301, Cylinder number 1 misfiring. Im going to change all my plugs and the Coil packs and ill keep my fingers crossed that this will fix the problem.

[@fcpeuro]

Crossing our fingers!

[@-A-M]

did it resolve it? I changed my spark plugs and coils. Still misfiring 2 and 4. I'm out of ideas.

thanks for the torque specs, doesnt look like Audi has changed plug torque specs in a good while.

[@fcpeuro]

You're welcome, TheRebuilt1!

Those popping noises are so satisfying

[@sellingnyhomes]

All videos for repair should be this clear, concise and short. Some of these videos just drag it out for three times as long as needed. Perhaps they are for dummies.

[@OneIdeaTooMany]

If you're smart enough to know that, you should not need a video to begin with

[@mattka5354]

Thank you posting. Great camera angle and very informative. How often should the spark plugs be replaced? I have a Q5 2.0T so I presume the steps and parts are the same. Subscribed!

[@fcpeuro]

Good morning Matt, a good interval for that motor would be about every 35,000 miles.

[@mattka5354]

FCP Euro Thanks for the reply.

[@eriktorres1232]

do you know the gap they have to be at I did 32 and it struggles to start and stutters ?

[@shaquizzle5548]

You saved me a lot of money! Thank you.

[@fcpeuro]

Happy to help!

[@Gnarp_darp]

Great vid...just curious where do apply the dielelectric grease on coil also do u recommend putting some on actual spark plug thanks?

[@fcpeuro]

The grease is applied to the rubber ignition coil connector. This helps the rubber boot slide onto the ceramic insulator of the plug. The grease also acts to seal the rubber boot, while at the same time preventing the rubber from becoming stuck to the ceramic. You don't have to put any on the spark plug.

[@Gnarp_darp]

FCP Euro perfect thanks appreciate the vids and I’ve subscribed

[@fcpeuro]

You're welcome!

[@audi247]

Great video very helpful and to the point. Thanks for posting!

[@chavenyenketswamy1498]

Why did you not remove those other small connectors. Ive seen other videos do this.

[@ringo9359]

I need to change the spark plug on cylinder one isit the one closest to the front bumper or the back one

[@fcpeuro]

Cylinder 1 will be closest to the front bumper.

[@mickyd1748]

So cylinder 2 would be 2nd closest to the front bumper?

[@TheTeddyBearNess]

i changed my spark plugs on my audi and it still had the check engine light on... no misfires and runs smoothly though...

[@shaquizzle5548]

You’ll have to use a scanner and clear the error codes

[@claudes1973]

I have a 2014 Audi a5. What part number did you use? Are they the same?

[@marzzgli1278]

I just bought a 13 A5 2.0. How are things going with your A5? I bought mine from a 3rd owner older couple and it has 118k miles. Did you replace your spark plugs?

[@claudes1973]

I haven't replaced mine. I guess I'll wait as the car seems to be doing good right now.

[@Exray737]

Hey man, great video. Do you prefer platinum series over iridium?

[@fcpeuro]

Thanks, Eray! So long as you use the manufacture recommended spark plug, you won't have any problems, however Iridium does tend to have a longer service life!

[@josephtaye9365]

Hey so I had miss fire on cylinder 2 I changed coils and spark plugs now I have missfire on cylinder 1 and 4? Any suggestions I fixed the intial cylinder now I have 2 to worry about

[@fcpeuro]

Hi Joseph, did you replace all the spark plugs and coils, or only on cylinder 2? I would doube check that all connections are tight and everything is plugged in, etc.

[@emoney5929]

Thanks man

[@vindieu]

for me that didnt go so well. the clips broke, and now the idling is so bad it might stall.

[@4ndr1uXxas]

Help! I changed mine to new ones and now above 2k rpms engine starts to stutter what should i do? I put bosch new spark plugs.

[@timcurrie1406]

What size thread does that torx screw have? Asking for a friend....

[@Emmanuel-ne3oi]

T30

[@rogerevelyn1131]

Hi good day, do I need to disconnect the battery before changing the plugs?

[@fcpeuro]

Hi Roger, no need, but it certainly does not hurt at all! A great practice to follow on any DIYs, especially for new wrenchers!

[@djkru5h207]

do I need to change coil packs as well or is changing just the spark plugs ok?

[@fcpeuro]

you can change them preventatively, but typically they're not changed until they fail

[@LuisGabriel1309]

Do you have to put Dielectric grease on the spark plug and where?

[@Squeedlyspooch3]

He mentioned not have to with those particular plugs because they were already coated

[@OneIdeaTooMany]

​@@Squeedlyspooch3anti seize. I think dielectric grease is for conductivity isn't it? Or are they the same

[@lossless4129]

I mean it’s not a preference thing lol use a torque wrench?

[@murcelamaya7736]

Hey so can I just you a 5/8 or do I need a special spark plug removal thing

[@ringo9359]
