I have a check engine light on my audi, when I take it to a non-audi mechanic I am told that the computer reads the catalytic converter and the transmission. Any advice you can give me on a cheap fix would be appreciated. Thank you!

Hi there,

I would like to know what the exact code are, so I can make a more exact diagnosis.

P0421, P0431, P0741.

Anything you can do to help would be great.

There is also the following emissions recall for my car: Vacuum supply within secondary air system is lost when secondary air vacuum hoses disconnect from system control valve. The rubber vacuum hose connectors split and separate from vacuum connection on the valve due to heat dissipation in that area.

Not sure if this has something to do with it, anything you can do for me would be great. Thanks!
