Hi,

When I view the readiness for my car (99 a4 2.8 Quaddro, prefacelift) it says Oxygen Sensor Heating, Oxygen Sensor(s), SAI, Evap Emissions, and Catalytic Converter(s) all say "Failed or Incomplete"... But the only error codes I can pull from any components are for the SAI (P0411), and some other random ones involving the blower motor and brake peddle light switch...

The battery hasn't been disconnected since November and I remember last summer all tests (except SAI) passing...

Any ideas??

 

You have to drive the car around for 50 miles or more, so the readiness can reset. its not ready yet as its not in a state of readiness.

if you erased the codes recently, that may be the reason why, the readiness has failed.

 

Good to know, it was the last thing I had checked after clearing a few codes so I'll check again after I've driven for a couple days...
