Knocking on Piston 3 1.8t AGU

V3 BETA TESTS
1

Hello,

I have knocking on primarely Piston No. 3. I changed:

  • Sparkplugs for new ones
  • Injectos for bigger and different ones (used ones though)
  • (changed from 4bar pressure to 3bar fuelpressure)
  • Interchanged the injector cables on 3rd and 4th
  • put new fuel pump and filter
  • put fresh fuel

I don’t have fuel prssure sensor

Can mybe someone have a look at my stuff?

Or maybe someone has an Idea for me to try?

Thank you

I would say that this mixture is too lean!

3

which lambda target would you suggest?

Never mind. I just broke one of the latches of the black connector. New one will take 3-4 days to deliver. So it has to wait.

Try 0,82-0,83 at 0.8bar!
