Help Engine light is on code P2062, P2063
 

Hi guys:

I have a 2010 E70 35D. Few days ago, the check engine light came on with the code P2062 & P2063. I have done some research on these codes for days; they are "Reductant Supply Ctrl Circ/Open" and "Reductant Supply Ctrl Circ Low".

Can some one help me on these issues?

Quoting from another site:
"Ok I ended up taking it to bmw, really nice mechanic there tested it for me, gave me schematics, told me the metering valve was pooched, just put a new one in and for the first time in months the check engine light is off!! Yay!!"

Hi Gregg3gs:

Thanks for your reply.
I did read all the articles from your links, and I also found some articles at another forum. Someone mentioned that issue might be the metering unit (1830780720) failed. Therefore, I took it off and checked it today and it was good.
I was lucky; I drove it around my area, the engine light was disappeared by itself. I guessed it might be the connector loose or bad connection.

Thanks again
