Idle actuator R1200RT

(1/3) > >>

Albert:
I have a R1200RT from 2009.
I am not sure yet, but I think there is a problem with the idle actuator.
Does anyone know or have the experience, if the new model 2010 idle actuator partnumber 13547714408, work on the 2005-2009 model R1200RT and replacing number 13547672966?
I read on another bmw forum that it is possible to fit the 2010 model on de 2005-2009.
The first one is Swiss made and €50 less. The last one is made in Mexico.


Any help would be appreciated.

Thank you,

Albert

The Idle Actuator differences between models (not just 1200RT) which has been identified is the shape of the brass knob at the end of the actuator shaft

The fact VDO changed production location to Mexico would not likely to be relevant

Whether the newer 1200RT one can be used on the older 1200RT I dont know but with the Idle Actuators I have seen the shafts have been replaceable

Albert:
Thanks for your reply.
I am gonna investigate this further.
I will let you know about it.

If there is somebody else with a suggestion...

Thank you.

What are the symptoms that make you think the idle actuator is faulty?

Albert:
I have this problem for a long time now. And it is becoming worse.
Between the 1000 and 2000 rpm is the motor not running well. When I steady the throtte handle somewhere between this range, the engine falters.
I very rare occasions, the idle drop off to 800 tpm, while waiting somewhere.
Sometimes when I start the engine, de machine is very rough idling. It is possible to drive, and above the 2500rpm its no longer noticeable.
But the best solution is, to kill the engine and wait for a while. And the start again. Mostly the problem is gone.

The Throttle positon sensor is replaced 2 years ago, and there is 15000km driven. So I don't think that's the problem.
I removed the throttlebodies, and clean them, also clean de idle actuators.
I also mounted new oxygen sensors.
The problem is still there.
I noticed, that when I perform a calibration of de idle actuators with the GS-911, the problem is gone for a while. But it don't last long, the last time it did this the problem was already there the next day.


So I think there is not much left, except the idle actuators.


What do you think about it?
