Ah, I understand both points.
I. I could only clean 'half' the throttle body on the vehicle ... and ...
2. It's probably safer to unplug the battery when moving the throttle body plate (which, in effect, removing it from the car does).

Thanks.

Throttle body is just a barrel of metal and only air passes through it and may be some gas vapors sucked from the T connection on top of air intake. I do not think it can get very dirty. The cleaning will not achieve anything.

Having said that I cleaned it after 127 K mile. It was fine, did not need any cleaning at all.

Regards,

Now concerning moving the plate in the throttlebody--I have opened it all the way open and held it there very time I cleaned the part--have never had a problem with doing this--thats the way I have done the procedure and it's worked well for me--
Same here, I open it by hand all the time for cleaning. Been doing it about every 9 months since I bought her back in 2000.
As long as you don't let the spring slam the plate closed you won't do any damage to it.

Jim--Noticed that you took the cover off of yours --did you do that to clean the workings? If so, do you use white grease or something like it before closing it back up? I bought a spare back years ago for 20bucks that came off a car with 15k miles--car was totaled and thought it would be a good thing to have a spare someday--Thanks

No grease, I used MAF cleaner on the dual pot that is under the gear that has the spring on top of it. The 4 white wires connect to the pot.
After cleaning it I sprayed on a little Radio Shack volume control cleaner/lubricant.

Thanks for the responce--never had the cover off of the one thats on the car--but did remove the cover on the spare--pandora's box thing I guess--I have heard that if you use another TB that you need to have the car reprogramed to accept the new TB--do you know if that is so or not? May only need to disconnect the bat and touch the ends of the cables to make the car relearn and program the tb again--don't know, but if I need to use the other tb would be good info before starting down the path--Thanks

You need to "reset engine adaption" by going to an Indy or using Ediabas / INPA on your laptop.

Reset adaptions, perform key-on key-off 30 second trick (varies for M52TU versus M54 motors) and you are good to go.

Is it possible to drive at all before resetting those adaptions? My garage does not have any programming available.

This update today suggests an important place to clean periodically:

Spring is here, the rainy season! Its very important Make sure that the water drain tube on the cabin filters are cleared out and free of debris. The drains are small and can get clogged with leaves easily. A Clogged drain on the drivers side will cause the water to back up inside the housing and leak down and puddle underneath the brake booster. The brake booster (sitting in water) sucks in the water and in turn sends it to the vacuum line then gets sucked into the intake naturally by the engine. Has it rained? Is your brake pedal very stiff? Car running rough? White smoke out of the tail pipe? Check the filer drain!! The brake pedal is the dead give away! Don't run the car until you clean out the water. The more it runs the more its sucking water in.

I have a 2000 528i that that wouldn't start. Among many other probs, it had Water inside the intake boots and inside the throttle body which killed it by the way. It was a mystery to me how it got there until today. This is the second time it's acted like that on me. Both times it rained heavily. First time it cleared itself out so i didnt worry anymore. This time it didnt so i Checked and of course the drain was clogged. Cleared the drain, removed the water around the booster and after a little while the everything was back to normal running condition.
