1999 Audi A6 Quattro Q&A
1999 Audi A6 Quattro Question: Secondary Air Intake Carbon Deposits
My '99 A6 has been well taken care of for the last 99,000 miles by me! The 6,600 prior it was driven from Alaska to Washington State with a photo of a mail order bride in the ash tray.... men are lonely in Alaska! Anyhoo, the engine light came on recently and my friendly Audi dealer tells me it will cost $3,000 to clean the carbon deposits out of the secondary air intake system. One of the technicians suggested that I use a gas additive to try to clean out the system... the auto parts dealer suggested a Mass Air Flow Sensor Cleaner. I now possess a can of this spray but have no idea how to use it. Can any one describe where I should spray this stuff? It is my last resort before I have to try to pass emissions testing in October.... don't want to dump 3 grand into an 11 year old car. Any suggestions welcome! - kcsaudi
