Hi all
I will be taking my throttle body off in the near future in order to change my CCV valve has anyone had any experience in cleaning the throttle body I have read some horror stories with people breaking it while cleaning and having to relearn the throttle body to the car, has anyone had any issues as I want to clean it while it out may as well really, but at the same time I don’t want to break it.

Throttle Body
I removed my throttle body recently whilst replacing my CCV. Cleaned it inside and out with petrol and a clean cloth. Mine was fine after. I think you'd have to drop it to seriously damage it. Make sure to fit a new gasket.

Thanks for the reply I did think it would be okjust wanted to ask round, also where did you manage to get a gasket for it I’ve looked and can’t seem to find one.
Cheers

You can get new gaskets at bmw:

But usually the gasket is still ok. They use viton gaskets and dont age that much; at least thats my opinion and I had my TB off countless times.
Obviously it wont hurt fitting a new gasket
There is no 're-learning the throttle body'
