Multiple Cylinder Misfires

[Mark_Reso2]

Hey Guys,

I've recently had the Emission Control System light on my dashboard turn on briefly in my Audi A4 Cabriolet (2004, V6).*
It turns on and then off again.

I've read the fault codes but am not that knowledgable so was hoping you guys could give me an idea what I'd have to expect if I were to bring it down to a mechanic. A vague idea whether it's a minor issue or potentially expensive would be great. And whether there is any DIY I could do on it?

When I delete the codes some of them come back usually the 7 below.

The car drives a bit jerky sometimes but overall works relatively alright. I've stopped driving it for now until I find out more.

Looking forward to any help/advice I can get. Thanks guys.

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

Recently when trying to check it I've also had the following code show up instead of the Cylinder 4 misfire:

16825/P0441/001089 - EVAP Emission Control Sys: Incorrect Flow
http://wiki.ross-tech.com/wiki/index...5/P0441/001089

Last but not least occasionally have gotten the following fault codes as well:

18149 - I believe this one means "Clutch Pressure Adaptation: Limit Reached"

18181 I believe this one means "Hydraulic Pressure Sensor 1 too large"

If you require any other information please let me know.
Thanks again!

Just to let you know that it is not all cylinders failing at once. I drove yesterday and it was just 3 of them, then after while more fault codes built up and it was 5 of them excluding any of the other fault codes mentioned above but including the following aforementioned fault code:

16825/P0441/001089 - EVAP Emission Control Sys: Incorrect Flow
http://wiki.ross-tech.com/wiki/index...5/P0441/001089

I'm currently in the countryside and will have my local mechanic have a look next week Thursday as I am busy with work until then so will keep you all updated but any thoughts as to what I may expect or your opinions would be really appreciated.

I will not be driving it anymore until the mechanic sees it.
