Hey Guys,

Ive been having an issue where i am not getting full power under acceleration. This happens only like 40% of the time.

The code I am throwing is 2B53. The code has to do with the throttle body apperently.

I want to try cleaning it out before replacing but cant find a good pic of it online.

Any ideas? Im guessing its on the intake manifold.

Thanks

 

It would help enormously if you told us what car you had.

If it's an R56 S with the N14, the throttle body is on the intake manifold(duh lol), down low passenger side. If you turn wrenches once in a while, getting the intake manifold off to get to it is cake. There's only 1 bolt that's hiding on you, but it can be accessed fairly easily with a long enough extension and the pass side wheel off.

 

A lot of people open the 'User CP' and build a signature so that others may know exactly what they are driving. Real easy to do and only takes a moment.

 

If anyone could put up pictures to provide a little more guidance, it would be greatly appreciated. i'm trying to do a top end cleaning, and I'm not too familiar with the R56 engine setup yet

 

The intake manifold is located under the airbox. Take off the airbox and you will see the intake manifold. The throttle body is located under the intake manifold on the passenger side (USA).

Follow the cold side boost tube from the intercooler along side the top of the passenger side of the engine it will 90 down then 90 to the driver side and then it goes into the throttle body. It's really hard to get a picture without the stuff being taken off.

 

Yea, intake manifold like cerenkov is right below the intake air box. The four ports of the intake mount to the back of the engine and the throttle body sets below.





Throttle body sets right on the passenger side and butts up against the bottom of the housing with that large seal #3



If you have the model and year I can get you the right parts. Check the past threads and did not see a model for you other then your Gen 2.

Thanks

 

thanks guys, very helpful. thats a lot more work than i would have expected just to clean the throttle body out

 

It is, but at least it doesn't have coolant lines running through it like my old car.

 

Welcome. Its not a very difficult job just takes some time. Its worth it in the cold weather due to short trips moisture/ oil vapor build up on the throttle which can cause "cold start problems" on very cold days like we have had here in the north.

 

Hi All...

Here in Vermont we experience a bit of the sub-zero (although it seems to be less every year). My 2007 MCS , just yesterday, after a night at -15 degrees started, sputtered, threw a couple lights...basically a repeat of what others have experienced. My question: to do a quick clean (spray some throttle body cleaner into it) can I just take the passenger tire off, remove the hose, and access it that way? Or do you recommend that I actually take the thing off the car where it can be cleaned properly?

 

A true zombie believer!

Ordinarily you would make a new thread for your specific case, but clearly you came here by way of googling mini coopers and throttle bodies... :D

Not to be ****, but I'd figure someone who choose the username realengineering would know intuitively that it's best to do it proper. ie take it all apart. Clean it all. and while you're there might as well walnut shell or soda blast your intake valves
