Car is 2007 E90 335i.
146k km.
Bone Stock.....NO Mods.

I had a DME issue.
Replaced DME MSD80 to MSD81 and coded to CAS and Key and VIN.

Everything was working fine....for about 2 days.
drove car lightly....
Then with INPA reset adaptations on the following:

Lambda Control
Fuel Control Valve
Octane Number

Now at Half Throttle not WOT I get a 30FF Half Engine Reduce Power and 2 Post Cat Lambda Codes at the same time.

Vacuum lines look good.
what else can I check?

Replaced All vacuum lines.
No more codes. And full WOT.

Found a weird hole in the vac line behind rear Turbo.
So glad I replaced all the lines.
Front and back are PITA.....but doable and only by feel.

Now to find better lines than the rubber lines I used.
Smelling rubber in cabin.
