<center><img src="http://pictureposter.audiworld.com/27789/error_codes.jpg"></center><p>16795 is covered very well in the archives- since I'm under warranty still, I'll have the stealership replace all the vac hoses, combination valve, and secondary air injection pump.

17887 is a little more tricky. The only thing I could dig up was:

A Bentley search suggested:
- Perform a short trip in Engine Control Module (ECM) (basic setting; display group 8 with ignition on and selector lever in "P" or "N")
- Check hose setup to pump or from the pump to brake booster
- Perform output Diagnostic Test Mode (DTM) in Engine Control Module (ECM) to check whether the vacuum pump runs or is activated

Someone else also mentioned it could be a leaky hose in brake vacuum system.

Anyone have any experience with this 17887 code?

TIA.
