Secondary air system in 40v motors - electric air pump: anybody knows about faults?
ECU shows a fault code: 17831, 17819 - air flow of secondary air system too low in both banks .
Air pump of that system has a filter.
Is it possible to clean one?
May be anybody knows how to take out that air pump?

I had a different cause, though most likely it's a loose hose.
Had the same codes. Dealer found VAC Rod for intake not operating: Inflet Manifold Remove + Reinstall: Faulty design, found one of two of the intake manifold's vacuum diaphrams broken. Found the rollover valve in the intake manifold had seized. Removed the intake manifodl. Replaced the intake manifold.

Yes, its are bi-xenon. Audi calls its "xenon plus"
Option
8ED - bi-functional headlight with gas discharge lamp, for driving on the right;
8Q3 - automatic headlight-range adjustment dynamic (self-adjusting while driving)
