Hi, I was having trouble replying. I either sent you a few responses (my apologies) or none of them went through. Please let me know if you got it.

Thanks

Hi, I sent you a few emails with no reply over the course of a few weeks. I installed the simulator on my 328i I am still getting code p0412. What can I check? I double checked all connections two times. Is it possible I got a bad unit?

Thanks

Having this same problem, everything is installed correctly but code keeps coming up + additional air temp code that wasn’t there before
