P1511 code after changing DISA Valve

[Charllow]

Hi guys!
I recently changed my DISA valve because the older had 170 000 km and was completely out.
So I bought a new disa valve, assembled it and plugged the connector but now I have 2 errors codes: p1511 and p0174.
I never had those errors codes before changing the disa valve so I think I did something wrong while changing it.

Did you encounter this problem before?
Thanks guys

P0174 is a Lean running code, usual cause is an air leak in the vacuum system, check all rubber hoses and intake bellows for splits or cracks that will be letting unmetered air into the engine. P1511 is a Disa Valve malfunction code control circuit electrical. Since you have had the Disa out and replaced check its connection and make sure the wiring is clean and intact, also make sure that its O ring is seated correctly and is sealing. A smoke test would pinpoint any air leaks if you can't spot them visually.

Hi, While my vehicle is away I have been setting up a rundown of things to fix/supplant on the BMW and just to give it a general check up. I chose while I appreciate utilizing INPA I needed to give a shot ISTA. After doing an underlying sweep I saw I had some deficiency codes. larger part of which can be disregarded and simply should be gotten however 2 stood apart to me. 002AA8 DME: Variable admission framework, servomotor actuation 002AA9 DME: Variable admission framework, servomotor 2 enactment The codes have sprung up beforehand and am presently simply further investigating it. At the point when I originally introduced the 3-Phase IM I had referenced it felt a piece need gloss (this was a while prior however just have yet on under 2k km since). Would its most reasonable justification be I was misled on buy and got a unit with awful DISA valves and would it be a good idea for me to investigate supplanting or reconstructing?
