      Basically the MAP sensor is on the fritz.
      Either do to bad wiring or the sensor is dying.
      Check wiring to sensor; replace / swap sensor if need-be.

      I have the same codes and a couple more.....
      P0238
      P0106
      P0300
      P0301
      P0302
      P0303
      Cleaned the MAP sensor and put new plugs in just to be safe. But it didn't fix the issue!
      It is intermitent, hesitation from the go always around 3000 rpm. MAP sensor makes sense since it feels like the motor is choking due to air or fuel shortage.

      Did the new MAP sensor adress your problems?

      Because you also have misfires on Cylinders 1, 2, and 3.
      Have you checked plugs? Ignition components?

      Put new plugs in and checked all wiring, no issues as far as I can tell.
      Problems are intermittent, I drive sometimes a couple days without issues and for what ever reasons it comes back again. Mostly when it is very cold outside.

      What plugs? Brand, model, and gap spec please.

      Have you data-logged anything with a VAG-COM?

      Champion Irridiums, have to check what model # they are. Should be a stock replacement as per manufacturer recomendations.

      Haven't done any data logging, don't have the capabilities (tools) to do that on my VW since it is not OBD compatible.

      I still lean towards the MAF sensor but don't want to replace it based on a guess.

      Why not a Bosch, or NGK?
      And why not copper (much cheaper!)?

      What scanner tool are you trying to use?

      Not with misfires; the MAF doesn't produce an electrical problem.
      You've got other things stemming to the issue.

      I have an Innova 3110 scan tool for my other vehicles, for the VW I have just a code reader and reset tool without any data logging capabilities.

      About the misfire I just wonder why it works for a couple days without issues and for unknown reason comes back after a while. Since it is on all cylinders it really can't be the coils since the chance is very slim that they all go at the same time.
      Especially since we make the coils at the company I used to work

      You're not missing on all cylinder; just the first three. Cylinder #4 is unaffected.
      Plugs can be a culprit; so can ignition coil wiring, and even a fuel pump relay.

      Just cleaned the TB and the IAT sensor, looked pretty clean.
      Will see if it makes a difference....

      besides the fact that you're in the wrong forum, Champion plugs are crap. those are the worst plugs you can put in a VW...

      Porsche's are not built to be something for everyone, but rather everything for someone.
