Do they even get dirty? Nothing but filtered air goes thru them no? I know oil and what not can make its way into the intercooler piping but I don't think it can make its thru the intercooler, up the charge pipe and into the throttle body.

Afraid it does, and then onto the inlet valves in a DI engine.

What engine?

Dealership told me my throttle body were dirty... They charged $395 to clean it... I rather do it myself & saved..."N54"

[phil200tdi]

Take off charge pipe.

Spray TB with carb cleaner, open/close whilst cleaning. Wipe with lint free cloth.

What problem are you trying to solve?

Idle not smooth when in neutral

Throttle body having a film of oil on it won't cause rough idle. Caked on carbon on your intake valves will do so.

You can get a new one for that price

It's amazing how not just dealerships but businesses in general rip people off like this. They just want to take people for as much money as they can get out of them. I feel bad you paid 400 for a throttle body cleaning, I mean that's ridiculous.

[amr_e90]

Yea that's kinda retarded that u paid 400 for a simple 10 min job with absolutely no supplies used or parts ordered. People get there carbon off there valves for 400 dollars

Thanks for advised good members

The throttle body never gets dirty, just gets a coat of oil on it which is normal.

I believe it's noted somewhere not to manually open and close the butterfly

[mweisdorfer]

I would use seafoam and run the engine. There is a DIY on that. I creates a huge amount of smoke.

[stormtrooper7]

I have an N52 and am just doing this now. Is the butterfly flap supposed to be completely closed or is there a little gap?

[Robdub89]

I know this is an old topic but don't use carburetor cleaner to clean your throttle body. They make throttle body specific cleaner for throttle bodies for a reason. Carburetor cleaners are too harsh and can mess up sensors and other seals
