Where is the seal between the intake pipe and throttle body?

Emry · Aug 22, 2015

I saw someone had resolved the 16825 fault code with swapping the seal between the intake pipe and throttle body.

Could someone show me a pic to locate this seal? It may help resolving my code too. A part number would also be good to have.

It's called the throttle body gasket. If unbolt the throttle body from the manifold, you can't miss it.

Not sure if that is. I have changed the TB gasket before. It's a flat thin sheet. But the seal is different:

Audi B5 A4 FWD V6 30v Engine Intake Pipe - 078129949C - Throttle Body Seal - ES#283685

Oh, I missed the word pipe... On the 1.8T I don't think there is much of a seal; there's a lip on the TB I think that the hose clamp has to clear, but I think that's it.

OK then it eliminates the possibility of vac leak from there. what else do you think I should check for 16825 fault code?
