Well the code is back on my 2004 Allroad for the SAI. A couple years ago I did the rebuild that Halik wrote up in 2008 with about one year's success. Now I've got -70 and -80% flow and can't pass the readiness test to get new tabs. (The pump does blast a goodley amount of air when hooked direct to the battery). I did patch one of the hoses between the pump and the comnbi valve with galvanizing tape when it cracked. Wondering if anyone has advice on where to tear into this issue first? (Also wondering if the "System Not OK Result Lambda Control" error is worth freaking out about.)

i eventually pulled everything sai related out on my allroad
you might be able to get away with that in your location, if we knew where that was . . .
if you need parts, i still have most of the parts and plumbing boxed up ready to ship
