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 knew what I'd have to expect if I were to bring it down to a mechanic.

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

17645/P1237 - Fuel Injector for Cylinder 1 (N30): Open Circuit
17645/P1237 - Ross-Tech Wiki

16825/P0441/001089 - EVAP Emission Control Sys: Incorrect Flow
16825/P0441/001089 - Ross-Tech Wiki

18010/P1602/005634- Power Supply B+ Terminal 30: Voltage too Low
18010/P1602/005634 - Ross-Tech Wiki

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
01826 - Ross-Tech Wiki

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

Thanks guys, much appreciated.*

 

If anyone else has this problem I did the following as some codes read may have been historic:
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 hopefully Ok.
This seems to be the procedure to check ...
