HELP! My 2001 Audi S4 will not pass emissions......I've had the O2 sensors replaced, vacuum hose leaks fixed, coolant temp sensor replaced, and new spark plugs......Still won't pass. The diagnosis codes are 1127, 1129 and 0300. What would you do next?

Thanks!

 

Those emission results would help... you can figure out things from them.

 

0300 is a random misfire code. most likely the coilpacks. the other two refer to you running rich in both banks. i would think this is due to a boost leak, vaccuum leak or a really dirty/clogged air filter.

do a boost leak check.

pick-up some coil packs.

these are the oem ones:

Audi B5 S4 2.7T > Engine > Ignition > ES#8037 Ignition Coil - Set Of Six - 058998105

third party:

Audi VW Ignition Coil (Set of 6) - Karlyn STI 058905105X6 | FCP Euro

Also clean out your MAf with some Maf cleaner. hope this helps.
