Help with explaining diagnostic values
 

Hello..

So, i have a 523i e60 2008 model that are sometimes when the engine is cold not just right.
The rpm drops up and down and the car (engine) starts to shake..
after a little while it stops and the engine is going like normal, around 650-700 rpm.

What is exactly the rpm value the engine is suppose to run on ideling ?


A friend of mine took a diagnostic and got these results :

current kilometer reading: 135391 km

Can anybody please take a look at this and give me their opinion on what the problem is ?

Thank you :)

Edit: i have more tests results if its necessery,

The last one I also had with the same symptoms. I changed my spark plugs and all was ok. The first one is also interesting because of the cat converter. I would change the plugs then clear codes and see which ones return.

I'd erase the existing diagnostic codes and drive it till the next malfunction. The codes above could be long gone, and rather misleading.

Thank you for the replies.

i can see on the service reports that in mai the coils was reaplaced due to the same problem i am experiencing now..
The plugs and all filters was also replaced..

but what about the lambda and nox sensors ?
since its only ( i think so) when its cold, could the sensors make this kind of trouble ?

the logs are deleted and i am having a new diagnostic on thursday..
Hope something good will come out of it.
