Emission Control System lit up?

[MarkReso]

Hey Guys,

I've recently had the Emission Control System light on my dashboard turn on and stay lit in my Audi A4 Cabriolet (2004, V6). 

I've read the fault codes but am not that knowledgable so was hoping you guys could let me know if the following is doable.

Please find the fault codes listed below with a link to Ross-tech:

17645/P1237 - Fuel Injector for Cylinder 1 (N30): Open Circuit
http://wiki.ross-tech.com/wiki/index.php/17645/P1237

16825/P0441/001089 - EVAP Emission Control Sys: Incorrect Flow
http://wiki.ross-tech.com/wiki/index.php/16825/P0441/001089

18010/P1602/005634- Power Supply B+ Terminal 30: Voltage too Low
http://wiki.ross-tech.com/wiki/index.php/18010/P1602/005634

This fault was also read under ABS but not related to Emission control system I believe:

01826 - Sensor for Steering Angle (G85); Supply Voltage Terminal 30

I'd really appreciate it if you guys could let me know what all this means, and how much it would set me back?

Thanks guys, much appreciated.

Some of these codes may well be historic, and the usual route is to have them cleared, the lamp turned off, and observe any reappearance.
Usually it's catalytic converter / lambda sensor issues that set things off.
A main dealer isn't needed to do this, but I'd hunt a garage down which is known to be good at diagnostics, if you can.

Thanks so much for your reply John, very kind of you.
Ah I see, that makes sense. As you can tell I'm very new to this.
I'll clear the codes and fingers crossed it won't reappear.
Will let you know how it went and thanks again for your fast reply and helping out.

After clearing the codes and driving for a bit the ECS sign didn't light up again and after rescanning no faults were found. So I'm going to observe a bit more and hope it won't pop up.

Thanks again John. You really helped me out.
