damn, that would've been the simple one to rule out :grin:

that code is specific to cylinder #1 .. wouldn't hurt to pull the plug out just to check it's condition.

Yeah can do.  Is there such sensor a a knock sensor but on each cylinder?  Engine runs fine by the way, just lose power (safe mode) when i get this code.

The knock sensor is doing it's job, but it can only adapt so far before it reaches it's limit. Usually it's a spark plug or coilpack that causes this - try swapping coilpacks 1 & 2 over and see if the fault code goes over to the next cylinder too.
