OBD Sensor Codes and what they mean?
My car recently failed inspection for the following reasons:
P0441- Evaporative Emission Control System Incorrect Purge Flow
P1136- No Description Available (Likely Manufacturer Specific)
P0455- Evaporative Emission Control System Leak Detected (gross leak)
P0422- Main Catalyst Efficiency Below Threshold (Bank 1)(5)
The car is a 1997 Audi A4 quattro.
I don't really know cars, so telling me how to fix it won't help me unless it is very simple. I would like to know what needs to be done and how much it will cost.
Any other answers/opinions. Thanks to the person that did reply.
well it looks like you have a leak in your evap system, maybe a canister, or solenoid problem. Most likely it is a gas cap or a hole in a rubber hose. the converter code means you need a new catalytic converter about nine times out of ten.
You need to go to a import repair shop or a audi dealer to get it checked out because your gas mileage should have dropped.
