Hi, could someone explain these codes for me?
The DME codes i mean.

 

what are the problems your facing?

 

Good call, because you can have a boatload of benign codes but if your car is running OK, don't worry about them.

 

im having problem with rough idle

 

the first 2 codes, dont worry about it. you didnt have the ignition on when you read the codes?
rest of the codes, the valve one i dont know. but the other could be your NOx sensor that needs replacing

can you tell us a bit more about the car? model/year maintanance done?

 

I'd definitely check for vacuum leaks, before doing anything else.

 

It’s a 2008 has 254xxx Km on it now. Bought the car last year and I wish i hadn’t. Changed almost everything that can be changed. Coils,injectors ,high pressure pump, spark plugs, gasket dont remember the right name for it right now but was really expensive. And more.

 

only after I got the code for the Egr valve the rough I idle started. And it’s really bad like the whole car is shaking and like it’s almost dying. But don’t get any engine light or loss of power only the idle problem. Was at the shop today told me it had to reset the adaptions will drive and after work if it gets better. I had the code 30E9 to begin with but after reading a forum people said to just encode a new catalytic converter and the code was gone soon after the nox codes began and after that the egr and rough idle
