At indefinite moments, i get bad throttle response, or should i say that there is no response despite i step on the pedal. The error code given is the P2102 (before a few weeks the P2103 also had come up), any idea what that actually is? Torque says its "Throttle Actuator Control Motor Circuit Low" but i have no clue what that is!

 

It means the throttle isn't opening up when you step on the pedal, basically. Time to check the wiring, and look up if there are any diagnostics listed in the Bentley manual for the electronic throttle.

 

P2103 - Throttle Actuator 'A' Control Motor Circuit High and Throttle Valve Position Control stuck Temporarily are the two I found that are described for that code.

Not a whole lot of information out there in the forums about these 2 codes. Let us know what you find out if/when you do.

 

Auto parts store said I had the same code on my R53 a couple months ago and for some reason I decided to charge my battery. Once it was charged up the code went away. It could have been coincidence but it's worth a shot.

 

I don't think it is the battery because i do have issues while pressing the pedal! The engine will not respond when stepping on it! Of course, if i shut down the engine and wait for 1-2min and start it up again, it will run smoothly!

 

Can someone tell me the Throttle body part number for my 2008 R56S in real oem, cause im mixed up in finding it?

 

Part number - 13-54-8-624-189

 

13548624189 is the newest part number and I PM you the info on the install earlier.

After i remove the air box, is it possible for someone to post a pic of the engine so i can understand where exactly the throttle body is located?!

 

This tech article here should be helpful, specifically figure 1.

 

Replied in the PM with link to intake removal. Then its right below it on the passenger side.

 

Finally i took it to a tech, he removed it and found out that the valve would not open/close when pressed manually with his bare hands! It was the mechanism that was faulty, that's why the valve would not turn when pressed. 2 out of10 times when pressed it would turn, the rest, it would stay stiff!
Replaced it and so far so good.
One question though, is your throttle body plastic or metal and does its say VDO on it?

 

Thank for the update, which one did you get the VDO version or the one from MINI direct.

 

I got the VDO version due to huge price difference! The VDO is plastic, is the MINI metallic?

 

Its plastic also. Just states MINI on it. Same thing. Both linked above.
