Don't even have a BMW but still watch your stuff can't beat real world knowledge from a man who knows his stuff.

[@BMWDoctor]

Thanks my friend I appreciate you watching

Use a vacuum hose to put your new plugs in , it will gently guide the plugs into there location and will provide a handle to hand tighten them, then simply pull off the hose off the tip of the spark plug , just a suggestion, love your videos, you helped me fix my 07 530i n52 , thanks, DOC !

[@cliffschumacher2804]

The new “recommended” plug has a much longer thread length. I’d be concerned. Can you explain why this is not an issue ?

[@bigdfitness5020]

Get your engine to top dead center on one cylinder then put the newer spark plug in that cylinder to see if it interferes with anything. If it doesn't you are fine.

[@MehrLovin]

This is actually the only easy thing I have ever done on my BMW. It's accessible and the parts are easy to get from Bosch. I think at 75k miles its time to do this no matter what. All you really need is a torque wrench and spark plug socket which is very cheap.

May you be blessed with positivity, bless you, thanx for the info ! 😊

[@paulseymour3395]

Do you need to disconnect your battery when working on electrical components like removing electrical seats etc ,

[@justdagoatgaming8460]

Can you show us how to diagnose the other potential issues within your videos? Such as this one ☝️ I want to diy my n52 and am trying to learn how to narrow down issues, to prevent spending extra money on parts.

[@mariusbrekkesunde7758]

How often should I change my spark plugs and ignition coils on my bmw 325i n52 2005?

[@lorenzotorres6783]

Hey bmw doctor. I've Been watching your videos since before i owned a bmw . Have you considered getting a magnetic spark plug socket? I love those! Hate dealing with sperate tools and the boot getting stuck on the plug. Thanks!

best expert Bmw master!!

[@chanhkhamkongsay6831]

Thank you dean i learn some thing about bmw

[@BMWDoctor]

Any time!

[@johnmorgan7262]

I assume that is a thin wall socket? The regular size does not fit my e90. Not fun to figure out in the middle of the job...

[@esdrasdiaz7109]

yes thin wall. burger motorsports sells theirs for like $14

[@maddoxohlson2528]

Do the spark plugs got to be torqued

[@antonmar2028]

Is it ok to change coils if plugs were replaced recently? Or do spark plugs have to be changed everytime the coils are replaced?

[@Laynestian]

Hi Dean, What is your opinion of the; ‘Denso’ iridiumSpark plugs? I think mine have done over 30,000 (10 years use). Will they need changing ?

[@clewis4651]

Obviously a Diesel doesn't have spark plugs, but do the glow plugs need changing after so many years to keep the acceleration up ?

[@BMWDoctor]

Man change them glow plugs every 20K TRUST ME I will be doing the same thing on my diesel EVERY 20K don't leave them in any longer then needed and let them seize in there. trust me I would recommend changing them every 20K without fail. there a headache after 100k they still will be after 20K but less risky. Yes there expensive but trust me the amount that glow plugs will cost you compared to extraction and even the time to extract glow plugs is more then it's worth to just actually replace them.

[@clewis4651]

@@BMWDoctor thanks fella just bought mine and its my 1st bmw so I'm watching all your videos and taking your advice thanks again 👍

[@Violet_Patrick]

why did they switch to the single electrodes one again? lol i just changed to the multi prong.

[@szatanserduszko6182]

I have a question. You change the ignition cores from that cylinder, where the spark plug had a bad look or from another reason. my english is not good enough and i do not understand good all the video. Thanks for answere.

[@adzzz8217]

Ive got a question, i have an bmw e60 530D 54 plate. Just this morning i got in my car i out the keys in and started it up. Quickly noticed my cluster wasn’t working. I-drive and everything is working as normal but the dials are not working and the light ain’t coming on on the cluster either. Any solutions or fixes?

[@jamesabroomeiii7552]

The triple iridium spark plugs that you just installed are generally good for 250 to 300 thousand miles they need to be removed annually to keep them from seizing to the Head but that is what GM and Toyota have been using for two decades they don't need to be changed every 30,000 miles that's what I put in mine and you can get them from Bosch or from NGK but anyone running a platinum plug I would definitely suggest changing over cuz they outperformed the Platinum hands down

[@jamesabroomeiii7552]

One thing to keep in mind I don't think y'all drive as much as we do which is very rare for someone to drive as much as I do because I drive 60 to 80 Thousand Miles every year and the 07 5:30 that I'm currently using by the time I get done it will probably have half a million miles on it I'm coming up on 300,000 now and yes I had to replace the CCV shit the other day because the valve was stuck and dumping oil into my intake I really do not like that design but I love this car it is an amazing machine and I will say have a 2019 550 and I prefer the 07 but I will say when I bought this car there was something off on the transmission and we put a 05 transmission in it the mount was not correct but because of what I have access to I was able to build an adapter plate cuz I have machine shop at the family-owned company that builds trailers the top that you would pull behind a pickup truck and then we also have to private machine shops that we can build about any damn thing you want I'm not the normal person but anyway I do watch most of your videos and I am vocal whenever I don't agree or at least something different maybe too vocal to be honest LOL but I do enjoy the content you put out anyway you have an amazing weekend and for whatever information this is voice to text my phone is attached to the Dash so everything I said may not be exactly what is typed thank you keep doing what you doing man

[@BMWDoctor]

No worries my friend and did I do something wrong on the video ? tell me what it is so I can correct it next time and I appreciate you always watching and commenting i realised you comment a lot and I do appreciate that and respect you for that as well as all the others that do.

[@jamesabroomeiii7552]

@@BMWDoctor oh no I was just communicating I think it's amazing that we can talk to people on the other side of the world unfortunately right now they made it difficult for us to interact with people next to us but no I didn't say anything that you did wrong if I had I would have said something LOL but anyway dude you have a wonderful evening no I do watch your videos because you have more knowledge on BMW's than I do for me years ago and it's been I left the mechanic shop in 2009 when my father passed away but prior to that I worked in a mechanic shop for about 5 years I was one of those people that would work on anything I didn't care what it was I have vehicles that I despise but I mean I'll still do whatever cuz the most aggravating thing I've ever done is a head job on a XJ8 that is the stupidest timing design I've ever seen in my life but but no I mean when it comes to American stuff I can work on a lot of that with my eyes closed and I realized over the years A lot of times when you work on European Vehicles do you have to stop and try to comprehend what they were thinking whenever they designed the vehicle because I remember doing a timing belt on a Passat and there's like a centimeter and a half in between the belt and the radiator fan the drive belt but they actually designed the vehicle to remove about 12 Bolt and then you install two long ones and the whole front end slides off the car to give you access to the front of the motor I find that ingenious and well-designed but I don't understand why they could not have made the car to inches longer LOL but like I said have a wonderful wonderful evening

[@MarioDallaRiva]

Doc, do you recommened preventative coil replacement after time even if you dont' have any issues? My '08 N52, only 75K/km, is on the original coils minus one which I replaced after a misfire (which it corrected). To save coin, I elected to only change the one (cyl1) coil at that time. Just wondering what you think? All six plugs were replaced when I did the coil. Thanks, Dr Dean!

[@jonowen6612]

Y’all listen to Dr. Dean. Before you put the plastics back on, check and recheck all your coilpack connections. Don’t ask me how I know this. I just replace all 6 coil packs. Is there a test to see if one is operating correctly?

[@attunedofficial]

I don't care what BMW says, that new design is garbage. They will support another style next year or some time down the road. Never mind, electrics are taking over. My plug of choice is the NGK Iridium I-9's in Delphi coils. Just real clean burns, but I switched to plastic valve cover too. I also like having all matching coils.

[@richardlittle1099]

This is awesome I learn a lot from him 👆

[@BMWDoctor]

Thank you 🙏

[@rsampson1495]

Respect my friend! Can you enlighten me please. I changed my spark plugs because I had cylinder 1 misfire! I change it. It read that I have a misfire in 3,4,&6 ! What changed? What happened in my case? Are the new sparks bad? Or my coils?

[@AhmedAli-hu8ng]

Nice information boss and great job very helpful video thanks allot

Most welcome

My bmw n52 brakes keep going to the floor no matter how much i bleed the brakes…. What u think is the issue??

[@shaine6580]

Where are you based? I have a 2007 E93, engine lights comes on for a few days, then off again (i call it my self healing BMW) i know its not the case. Revs sit at 600rpm idling and cuts out alot. Dangerous when i reach roundabouts/give way. I need you to fix this for me. Where can i find you

Which brand is best for coil packs on a N52? Oem ones are old type of design I've been told updated ones are available but what ones 🤷‍♂️ any help would be great

[@Laynestian]

Febi Bilstein or Bosch..

Whats the torque spec for spark plugs ?

23nm

Ive always put a smidge of copper slip on the threads of spark plugs

[@chrisroy4655]

So helpful thank you

[@jefortysix9018]

What plug upgrade for m54b22 pls? Thanks

[@gnomebmw]

One problem I ran into when changing the plugs and coils on the N52 is the new factory BMW coils fit oddly - the car sputtered and misfired like hell after the change. It turns out the new coils are stiffer material and didn't seat properly to the plugs and seal to the plug holes. Had to pre-install the coils 2 or 3 times and rotate them just right to get proper connections and eliminate the misfire.

[@Laynestian]

I wonder if a spray of silicone would help?

[@dyyylllaannn]

Thanks for this comment, I was at a loss. I took it out and reseated and voila

Hey Dean what is your Amazon channel link please

[@rotorblade9508]

I just replaced 3 coils this morning. It had maximum -7%ltft and now is bit lower mostly +2%, on bank 1. The other bank was low. It felt a bit smoother though. Anyway the new coils are Delphi because I look up on realoem and the oem,s are also delphi. Now I could buy an oem to see the difference idk, or buy another 3. These are 25€ and oem’s are 40.
