BMW S54 ITB REBUILD: Individual Throttle Body Service and Maintenance

[@SeriouslyEpic]

You are a good human being.

[@stewartsimpson2236]

Great video!! 👏👏 On my car there is some corrosion on the rotating rod; From watching this it would seem I could remove the rod by removing the bolts going through it while leaving the throttle bodies attached to the car to clean it? If I could that would be brilliant thanks 👍👍

[@mauricem7143]

Finally! A proper video on this 👏👏👏

[@OnlyyDans]

Glad I could help 🤝🏼

[@michael9218]

Excellent video! It would be very helpful to show how you cleaned out and lubed the roller bearings. This would seem to be very important if your throttles are sticky throwing a code. Did you shoot them in place with a cleaner? Can the bearings be removed with a pick?

Best in the business! 🤝🤝

Thank you for the excellent video. Where in INPA is the option to open the ITB's for measurement?

[@OnlyyDans]

Sorry, I misspoke in the video a lil bit. You can activate the servomotor via DIS or MoDiC. You can use INPA to read and clear adaptations (Select "Clear adaption values selectively" then F3 key is "Throttle Valve Adaptation"). In DIS under OPERATIONS you select Engine Control > Then under Engine Control you select Actuator, then Actuator DMS. This will communicate with the DME. After that, select optin #3 which is Service Functions, and then #8 on the next screen which is "Set el. throttle valve controller full-load stop". Just follow the instructions but it'll say to make sure the key is in position two

I really like the level of detail you give to this rebuild. I just finished rebuilding the itbs last weekend and only now I came across your channel and saw this video. If you can answer 2 questions, it would be great because I'm confused and I'm afraid I've done something wrong. Each itb(2-6) has 3 washers, 2 identical and 1 very thin. You said that the 2 identical ones are directional. What do you mean because I didn't see any difference, they are perfectly flat, not conical. Am I missing something? If you put a light behind can you see the light on the other side on the edge of the flap?Thank you very much and I hope we will see more good videos like this in the future!

[@OnlyyDans]

@@87wlo sorry I didn’t see this sooner. Believe it or not, I’ve taken apart older ITB’s and newer ITB’s and there’s very slight differences between the two. If your washers aren’t directional, then you’re good to go. As far as the light, cylinder 1 is always the furthest open (doesn’t seal perfectly, and this is normal). If you’ve followed all my instructions with the throttle set screw and adjusted them properly, and they’re within spec then you’re good to go. The computer and engine will run in the factory parameters without issue

[@Voges2023]

Can you show your vapor blasting and zinc plating process?

[@OnlyyDans]

@@Voges2023 I’ll do my best next time

[@db74ful]

Great video, I’m just about to do this on my S54, do you ever match mark the ITB’s to the head for better flow?

[@OnlyyDans]

@@db74ful not worth the time since the throttle plates are still the same size. If you buy Dinan bodies, they’re ported with bigger plates to compensate, but expensive. S54 head already has a really nice cnc’d intake port, I doubt porting the backside of the housing will give you any benefits worth the time and labor

[@db74ful]

@@OnlyyDans thanks for the comment, I’ve had the head’s been polished and ported so it may be worth offering them up just to have a look see, but you maybe right. I’ll look at those Dinan bodies.

[@rubenabascal2a]

Mate, do you know where to find the throttle body plate screws?

[@raduorban]

👌🤌👏

Do you rebuild for customer I have a set that I would like to get rebuild

[@felixchristensson2603]

Hi do you change bearings or leave them in?

[@OnlyyDans]

@@felixchristensson2603 I couldn’t source the right spec needle bearings so I do my best to clean these out and prep them with grease

[@robgill48]

@@OnlyyDans Did you need to protect the bearings during vapor honing?

[@OnlyyDans]

@@robgill48 absolutely! The more debris you get in there, the harder it is to clean out. You want them as smooth as they can be

[@felixchristensson2603]

@@OnlyyDans Thank you for the reply

[@NicholasWood1]

@@OnlyyDans if I could piggy back off of this, what did you use to cover the bearing to protect while spraying. Thank you for the video it’s dope. I’ve learned a lot from your s54 build videos

[@jasonherskind8912]

What do you charge for this service?

[@OnlyyDans]

Depends on the condition because that will equate to time. Also if I'm purchasing sensors or anything else it would affect the price point as well

[@TheFoxSaid]

@@OnlyyDans How many hours roughly on this particular one if you weren't filming?
