BMW 550i F10 Spark Plugs and Ignition Coils DIY N63

[@charless2684]

Just a quick thank you for the video. Changed my plugs and coils this weekend using your instructions. Super easy and my car runs like new again.😊

[@brianl5607]

thank you for the video. I had the (Drivetrain Malfunction, drive moderately) warning and shake happen to me the other day... Went to diagnose the issue at my bmw gallery and "thankfully" it was a spark plug issue misfiring on the cylinders. Ordered the spark plugs and I am waiting to receive and do the replacement myself. This could have been a decent price tag at the dealers, but watching your step by step process gave me the confidence to do it myself. Subscribed!

[@SimpleCarGuy]

It's an arm and a leg at the dealer and a fairly easy DIY! Good luck and hope it fixes your issue.

[@mikeb9517]

Hey Brian L, same here. I am awaiting my orders and will be doing it myself!!! Thank you for perfectly describing my issues as well!! The creator of this video , is the msn!! Thank you and I have also subscribed! Your teach style fits my learning style perfectly!!!

[@brianl5607]

@@mikeb9517 Following these steps, you will have no issues. I had everything but the ignition coils and plugs disassembled and laid out on the same day of delivery. Made for a quick install. I haven't had any "Drivetrain Malfunction" warnings or shaking since replacing all the plugs. Car runs and sounds healthy. I replaced all of my ignition coils a month after for peace of mind. This spring I'll replace the fuel injectors, also for peace of mind lol Good luck on your install!

[@mikeb9517]

Hey Brian L Hey the dealer or whoever tightened the first spark plug in the first cylinder way too tight to remove! I fear if I continue fighting it, it may break!

[@brianl5607]

@@mikeb9517 Hey Mike, I also had an overtightened spark plug during removal. I eventually got it free by loosening and retightening the spark plug over and over with the socket wrench. kzbin.info/www/bejne/b4C3pKhrgs6tiac I hope this link helps.

[@dmarco5396]

Great video. I’ll be doing this service soon. The dealer wants 1,500 just for parts. I’m glad I have an Alternative.

[@SimpleCarGuy]

Thanks for watching! It’s really isn’t that difficult of a job and if you get the parts I got it’s much much cheaper. I haven’t had any issues since.

[@walters0331]

Couple things to mention if doing this for the first time, as I just learned the hard way. Know how to release the O2 sensor clips (I just broke mine). When removing the intake/air filter pieces, be VERY careful not to move the plastic Charge Pipes too much. I broke both of mine while trying to pull off the air filter pieces, since the whole thing is plastic, including the tab that holds each charge pipe to the turbos. This really sucks to find out after you snap them off, since the entire charge pipe needs to be replaced because it is a one piece molded piece of plastic.

[@SimpleCarGuy]

Thank you for the extra info. I hope it helps someone and sorry that your clip broke!

[@PaulBroni]

What did that set you back? I just did my coils and plugs and thought it was simple... right up until I started the car and got a drivetrain malfunction message with car in limp mode. OBD doesn't seem to show any errors.

[@SimpleCarGuy]

You need a BMW code reader to see those codes, most likely.

[@videogamevoyagers195]

Good job man. One thing I would note is when you remove the air filter housing, you don't need to remove the screws for the heat shields underneath. It can come out with the housing. You'll run the risk of dropping the screws in the engine bay, which really sucks.

[@SimpleCarGuy]

Good point! I did it this way because it seemed easier while i was pulling them out. Noted for next time. Thanks for watching!

@@SimpleCarGuy What p/n should I use for the coils ? My car is 2014 N63TU. Eldor brand cost close to $300 for 8 coils.

[@SimpleCarGuy]

[@SoulDrawn]

The one thing I've come across is the two screws on the airbox. You could just yank the thing off without having to do those screws because they attach the heat shield to the stock airbox; the little ball joint things hold it on

[@PaulBroni]

Mine was the same way. No screws to remove the box.

[@BMW4631]

Hello Thanks for posting! great video and i own a 2014 550i M sport so when i get to that point i know where to look for info. Just on a side note tho, i still own a 2008 550i sport and my first change of the plugs came at 126K miles and it only slightly improved sharpness of throttle (none of them had failed up to that mark). Also at 163k miles today i only had to change 1 ignition coil out of the 8 and the car is still running strong, touching wood :) (PS: i have a brand new oem spare ignition coil in the trunk in case it sarts misfiring while on a road trip...)

[@SimpleCarGuy]

Thank you for watching! If you have any questions about your F10, let me know. Are you sure your 2008 didn’t have plugs and coils changed before you got it? (Unless you got it new) I had a 2008 335xi coupe before and had to change plugs and coils around 70k as well.

[@BMW4631]

SimpleCarGuy yes 100% those plugs and coils where never changed before. The car looks new inside out. I did change the water pump at around 100k miles and besides the stem seals and the alternator bracket the car was bullet proof. Let’s see how the 2014 stands up to the test of time... i do know that i have the N63 TU installed so hopefully i’ll get lucky on the reliability side. I keep my fingers crossed :)

Thank you..we have a 2011 X6..two weeks ago we got the "reduced engine power" and the shake..turned the car off/on and everything was good for a week..got another "reduced engine" message and shakes..BMW said it needs all 8 coils and 8 plugs.. Plugs are $45 each ($885 parts and labor) Coils are $143 each ($1,675 parts and labor) Oddly enough they just changed 2 coils last year Any videos or tips on crank-case pipes (connecting line)...OR..Turbo inlet seal (gasket)

So I did the work and my car is still shaking. And scan still reads misfire? Did an oil change cause it was suggested. What else can you recommend?

[@SimpleCarGuy]

Did you clear the codes? If you had a misfire, replaced the parts but not cleared the codes, it’ll continue to deactivate that cylinder. If that doesn’t help, it’s your injector 9/10 times.

[@Loso3280]

Yes the codes were cleared. And it still came up as a misfire. So you may be right about the fuel injector unfortunately. Is that a hard fix? Do you have a video on that?

[@reaperproductions8]

Misfire in 6 and 2 on my 2013 550i xdrive and would go into the drive train malfunction mode so replaced all (8) coils and spark plugs and after the 1st start up it came up right away the drive train malfunction that is so went to maybe try to just remove codes via code reader at local shop and it showed (2) “Permanent” Codes or PDTCs. In those two cylinders 6 and 2. After I replaced the coils and spark plugs perfectly fine. So now it’s obviously to fuel injectors. I assume I would just need to get the (2) for the two misfire locations rather then doing all (8)?. Also, how to video for this? Replacing a fuel injector at home ?

[@SimpleCarGuy]

Since you have replaced the ignition coils and the spark plugs, cleared the codes and got the same codes again, the most likely culprit like you said are the injectors. As far as replacing all 8 or just the 2 that are giving you trouble, that really depends on how you want to handle it. If you are doing it yourself, I would probably just do the 2 and if more go bad in the future, just do those at that time. If you are paying someone to take it all apart, it would probably make more sense to get all 8 done so you aren't paying twice for the same job. I dont have a video on this engine, but I did replace injectors on my BMW Z4 which is somewhat similar: kzbin.info/www/bejne/f4CZqainl6hppK8. Of course you'd need a different removal tool.

Hey Bud, I've done all of the steps. Changed 8 Spark Plugs. But the car is shaking. Do you have any recommendation?

[@SimpleCarGuy]

Did you change the coils? Usually coils are the issue, people do spark plugs just because you are already there and it’s cheap in comparison. If you haven’t changed the coils, you can switch the coil from the misfiring cylinder and see if it moves with it. Then you’ll know for sure.

[@mikegusenov1020]

SimpleCarGuy last time i changed coils was like a year ago. Should i still change it?

[@SimpleCarGuy]

I would switch the coils like I mentioned to see if the issue moves to that cylinder (I assume you have a scanner). If the problem does not move with the coil, you might have injector issues.

[@SimpleCarGuy]

Will it last to 150k? Sure, but how much work will it need to get there is kind of hard to tell. The TU version of the engine is MUCH more reliable as long as the oil has been changed every 5-7k miles and not 15k miles like BMW recommends. My buddy with an n63tu X5 has the valve seals changed under warranty as the car started to smoke a little. Other than that, I haven't heard any horror stories.

It was the first time as far as I’m aware. I got the car with 30k miles so I don’t think any of that work was done. If I were you, I’d definitely wait at least another 10k miles and then change it. If you get any symptoms, light misfire pulling hard on highway or anything like that, replace sooner. Thanks for watching!

[@NYCBrappVlogs]

I just subscribed to your channel. I have the same car. I recently started having problems & check engine light. First one was Dmtl fuel pump leak. After driving for 2 days. I did a burnout fresh tires I got then after it went into limp mode & start to show drive train malfunction in the engine. I drove it for a little to park it and start smoking from the engine but the car wasn’t overheating. Put the computer on it the error codes were running a code saying running lean & all cylinders misfire. It starts back up without a issue but it goes back into limp mode & sometimes shut off on its own. However I noticed a air seeping sound from the engine when it’s being rev. Please can someone help me find out what could be the issue here

[@SimpleCarGuy]

Have you done the spark plugs and coils yet? At the very least I would swap them around to see if the code move from one cylinder to another. If it does NOT, it's most likely the injector. Thanks for subscribing!

[@NYCBrappVlogs]

SimpleCarGuy it’s all cylinders that’s having the misfire. But no I haven’t done the spark plugs nor coils yet.

[@SimpleCarGuy]

In that case I would think it’s the HPFP, but it’s difficult to say without seeing the car, resetting the codes and seeing what comes up first etc.

[@NYCBrappVlogs]

SimpleCarGuy ok but wouldn’t a HPFP error code appear?

[@SimpleCarGuy]

Not necessarily, it could be mechanically bad and not electronically. I had the little plunger break on mine once. No codes for the pump.

[@kirkcampbell9276]

Is Bosch a good coil to use in bmw?

[@hochh6978]

BOSCH are good for sure. Anyways, make sure you test misfires under high load. You can check them by using CarScanner app and a OBD2 adapter plug. If you don't have misfires on the 4th and 8th cylinder, you're good to go, otherwise, I'd swap the coils with the cylinders that don't misfire and see if it's the coils that don't give the stable ignition.

[@trencher7]

Are you supposed to change coils every time you change plugs??

[@SimpleCarGuy]

No, but usually when plugs go, coils are too far behind. So, it’s easier to do both at the same time. If you are trying to save some money, then you can just change them one at a time when the engine starts misfiring.

[@gochuy1]

I did everything step-by-step I bought the same spark plugs and coils and when I turned on my car I get a drive train mount function. Please help 🙏🏼
