Thanks for a great video. I watched it 2-3 times and made some notes. I was able to successfully replace all the 4 spark plugs on my Audi A4 2018 2.0 TFSI. The car servicing place quoted $500. I managed to complete it by following this video after spending only $105. One note to anyone watching this in future. The spark plug gap for my Audi was 0.028 inches. Some websites mention 0.032 inches, but when I took out old spark plugs and measured them, they were 0.028 inches. The spark plugs I got from auto part store were pre gapped to 0.028 inches. Thank you again @DIY Detail for your well made video.
A month or two back the stealership "urgently" wanted to replace the plugs on my 2018 A5 Sportback. They quoted me $210. That seemed awfully high so I held off. I assumed it might be that it was difficult to get to them and/or required tearing apart half the engine to do so, hence the high price. I was probably going to have them do it when I took it back for a couple of recalls. Glad I watched this video first! 20 minutes and $40 of my own time is a much better deal and I come out of it with a much better set of plugs installed! Thanks for the great step by step and torque specs!
Your videos are so helpful. As a female I feel like the dealer sees me coming from a mile away. If your friend is willing could you replace the spark plugs on his 2017 VW Passat R-Line? You explain everything so well I believe this is something I could do on my VW myself. Thank you again! You have already saved me a lot of money by replacing my cabin and engine air filters!!
I’d recommended having a thin 10mm wrench, when I tried to take off the nut the whole bolt started spinning and broke the connector off the wire, so a thin wrench to hold the lower bolt as you take off the top nut
Great job on the video! I was able to replace 3 plugs, plug #1 (far left) was cranked in so hard I couldn't break it loose by the audi tech who replaced them last time before I bought the car. A call to the local dealership - not the same as the dealership that swapped the plugs last - in the morning coming for guidance. Interesting is that when I searched/googled the video for my 2016 A6 2.0T none of them showed the coil pack bolts and ground wires like your video of what you said is a 2017. I noticed them on a video for an oil change on a 2017 so I modified the search and found your video. Odd.
Thank you so much for this, steps were great, worked perfectly after this. Only one thing though: for me, the 10mm bolt and nut would rotate with one another, putting risk of ripping the grounding wire. To fix this, I had to get a very thin 10mm wrench to hold the bolt, while a ratchet on the nut to break it loose. After that, it was normal.
Hi. Thank you for your videos. You make me want to find my tools for car servicing. I completely gave up on doing that myself once i bought German cars. I used to drive Japanese and they were so easy to change
Dealer wanted to charge me $246. Thanks to your video I only paid about $60 for the plugs and another $30 for tools. My only note is that I had to return the 6” extension for a 10” as the handle of the 6” wouldn’t clear.
If anyone is curious they make a tool to help remove the coil packs..one version is super over priced around $200+ and the ECS tuning knock off is like $60ish. Not critical since we all just saw you can do it without the tool but it does help sometimes.
There is a mistake in the video regarding top nut torque. Official ELSA AUDI guide torques: Table of tightening torques for installation: Component/fastener [Nm] Spark plugs 30 Bolt for ignition coil 10 Nut for earth wire 9
Do you suggest disconnecting the battery before doing all this or it don't matter? Looking to replace spark plugs myself and avoid the service cost at the dealership
Hey! Thanks for the kind words :) I do have a video on how to do an oil change on my channel. I’ll post it here th-cam.com/video/3yuXQlCh56c/w-d-xo.html
I tried removing the coil pack on 2014 tfsi audi a5 so I could change the spark plugs but the coils would not come out! I've changed spark plugs on multiple cars in the past, so it was quite puzzling to me that none of the coils wanted to come out. I couldnt get any of the the coils out ! Can someone advise?
It was not totally easy, some are harder than others. I think on 1 and 3 I used an angled pry tool to get them loosed up a bit the had to work at them before them eventually popped off.
@@CLane-nb4vl Great question! Audi recommends changing it at 30k only if you have the 2.0L TFSI Flex Fuel engine (or the RS7, S8). If you're like me with the standard 2.0L TFSI engine, you should replace them around 40k. There's no harm in replacing it early (granted you have no misfires, etc). The only thing is you might be replacing a part that may still have a good amount of "life" left on it. You can always inspect one of the spark plugs and see how bad it is!

Tips from video ( for me when I come back to it)
Gap check-
Spark plug torque - 30nm.
10 mm bolt - 10 nm
10mm nut (the one on the top most) - 7nm
The most top should be 9 nm according to the official service guide. Not 7 nm.

Odd.
You mentioned 5/16” in the video and the link you meant 5/8” for the plug socket
Which one is it ?
@@asmith614 5/8”

Running into this same exact issue atm except I don’t have a thin enough wrench 🥲

There is a mistake in the video regarding top nut torque. Official ELSA AUDI guide torques:
Table of tightening torques for installation:

Is it a 5/16 socket or 5/8?
Edit, 5/8 socket will work, and can be found on autozone for $13~
Thanks! Just changed my plugs thanks you your video! Cheers!
Glad it helped!
great video really appreciate it

Thanks for the video!
Thank you! Easy to follow!
Thank you for this video! Helped me out a lot
Great video... I have a 2017 A6 (C7) 2..0T Quattro but it is the same engine setup... You have any videos on oil changes and torque of oil filter cap?

Good Stuff!
A 'thank you" is in order!
Cant understand how to remove wire sockets until this video, german engineering so complicated compare to japanese
Excellent video! Thank for sharing.
Glad to help!
Socket size should be 5/8 inch or 16mm
How often are you suppose to replace the Spark plugs on a 2017 Audi A4 B9?
Hello! Spark plugs should be changed every 40k miles or 6 years
DIY Detail I’ve heard 30k. Is that just BS? Any harm in doing it at 30 rather 40?

Does it matter if its the TDI or TFSI engine?
The technique should be relatively the same. The plugs may be different due to the diesel/gas difference
@@DIYDetail The plugs on a diesel?
Do anybody know how to change the 2017 turn signal light in the front
Unfortunately I’m not too sure but hopefully someone watching this could help! Have you tried checking the Audi Forums page?
After watching your video, all i can say is lefty loosy, righty tighty.
This poor dude, has a hard time discerning between Righty Tighty, Lefty Lucy.. lol
Could have been an excellent video -if you had not used the repetitive annoying music jingle..
