Vanos replaced knocking noise afterwards ...need help please.
 

HI guys
Engine was idling fine with a little of hesitation not alot got code p0012 ....so I swap maf sensors a little better
Code says intake solenoid so swaped boths solenoids and got the exhust now..! so that means that the solenoid is the culprit. So off I go to get a new one ..and replaced it ...turn on the engine and hear this clack clack clack noise from engine like out of time ....my question is did I install them incorrectly . :dunno: is there a way to install them. ....is there certain angle orientation or is not all the way in ....thanks in advance. .....2004 e53 4.4is sport. :dunno::dunno:

Did you buy the right sensor? Some sensors can not be swapped from one side to the other.

Both from the same bank 1 I put the intake one to the exhaust and viceversa. ....both look exactly the same ...
Thanks...

I think the only way to screw up the install is to not push them in far enough. I remember when I did mine had to give some good pressure to get them to click in all the way. Kind of a weird angle too and can be tricky to do. That would be my first guess
