hey i have a 2001 Audi 1.8t A4. it has about 88000 miles on it. i have a check engine light on.. i went to autozone and the error codes that came up were:
P0402 &
P0411
Any help is greatly appreciated.. Thank you!!

if any1 can reccomended me some help without gettting ripped off its truly appreciated.

 

secondary air pump issues. i had the 0411 code. in my case it was the kombi/combi valve. was dirty and wouldn't open. sprayed some p.b. blaster in there and let it sit. no problems since. it could be your vacuum lines, secondary air pump, or kombi valve.

 

You can try spraying down the kombi valve with brake or carb cleaner, and if it doesn't work...

Get the SAI blockoff plate from Integrated Engineering, get your SAI codes tuned out by k0mpresd from a couple of the other Audi forums. He's been slow lately, though, so be prepared to be without your ECU for ~2 weeks. Only $50, though (if he hasn't increased it). Much cheaper than a new SAI pump or kombi valve. Anyway, lastly, block off the hole in the airbox - I used two fender washers, a bolt+nut between them, and some RTV to make it airtight

 

does any 1 know any good mechancics in nyC?
