BMW E46 3 Series M3 Throttle Actuator S54 Replacement And Intake Manifold Removal DIY

Hello Subscribers! Please remember to like and share this video. In this video I show you how to replace the throttle actuator on an E46 BMW 3 Series M3 with the S54 engine. This is a complete video showing you how to perform this repair. There is additional value if you need to remove the intake manifold for any repair as I go over the complete steps to remove and install the intake manifold as the throttle actuator sits under the intake. And I add some tips and tricks to get the job done as easily as possible.

Thanks for all the effort in filming all the awkward angles of this not-so-easy job.

[@AskTheCarExperts]

So true 👍 I hope it helped. It was a pain. Not going to lie, a lot of the filming is a pain because I do it all myself most of the time 😀 Thanks for commenting.

Awesome..

[@worldsails2000]

Nice walk through. Did you go with an OEM or after market throttle body? I have an S54 as well and will need to replace mine soon.

[@AskTheCarExperts]

Hello, I did purchase it from my local dealership. I know in the US market this gives a 2 year parts and labor warranty if it where to fail. Also since the job is a bit of a pain I thought going OEM would be the safest bet. I hope my video helps when it comes time to replace yours.

Good Job! Any calibration needed after the install?

[@AskTheCarExperts]

Hello, Just cycle the key off an on and the throttle will do a relearn. No extra step needed.

[@nenorv11]

Thanks

[@nenorv11]

Copy that. Thanks.

Did you get any fault code readout for the actuator? Was the EML light on? Thanks!

[@AskTheCarExperts]

Hello, Yes the EML light would come on and there was throttle faults intermittently. Often with a key cycle the issue would stop but after a few weeks the symptom was getting more frequent.

[@comecorrect8365]

⁠@@AskTheCarExperts were u getting limp mode?

[@DBMOEtv]

Did you have to run INPA after?

[@AskTheCarExperts]

No need to run any additional test plans. I would cycle the key on and off with out starting first and then start the engine.

[@comecorrect8365]

How did you set the set screw on the actuator? Count threads?

[@AskTheCarExperts]

If you have to replace the linkage then that would be a good idea.

[@comecorrect8365]

Did your actuator come preset? Ig it could also be called a stop screw its the tiny allen on the actuator.

[@tim4722]

What was the reason for replacement? Fault code 107?

[@AskTheCarExperts]

The issue was throttle position faults. At first it was intermittent then turned permanent.

Does causes limp mode

[@AskTheCarExperts]

Hi Adrian, Yes it can cause the vehicle to go into limp mode
