Anyone have any experience with CEL code 411. My neighbor downloaded the code with his scanner. He told me it had to do with the secondary air injection unit that feeds the diverter valve. What have you guys seen?
i had that code, it ended up being a vacuum hose that ran from the little valve thats above the airbox to a valve on the backside of the intake manifold (of couse, this was on a 2.0). If the vacuum hoses are fune, and the air pump runs when you first turn on the car, it will probably be that valve above the airbox. But 90% of the time, it will be a vacuum hose.
I bought the VW New Beetle Haynes Repair Manual for 1998 thru 2005 and am kinda disappointed. Since it covers so many years I couldn't find any information on the specific problem I was looking at (Tiptronic).
