Clearing Porsche-specific codes with Durametric

[wyovino]

MY2000 C2 Tiptronic, stock intake. Probably the original MAF

 

I have a few questions regarding codes that I found while using a Durametric.,

 

1.  I see a P1671 Porsche fault code 407 - Control unit faulty Signal implausible.

Last year I forgot to reattach the MAF connector after doing some maintenance. I got a CEL for ABS and PSM and quickly found and corrected the problem.     Could this be related to that event?

   

2.  Tiptronic codes  - 3 years ago I brought my car to a transmission shop recommended by my trusted Indy because I felt a bit of slipping in 4th gear.   They replaced the  valve body and did a full filter and fluid service.  They told me that one of the clutch packs is leaking and that eventually I'll need a rebuild., but it's      not that bad now.  It hasn't gotten any worse and I think the service actually helped a bit.

 

    The Durametric is showing these Tiptronic codes.

       82 P1823 Pressure regulator 3

       81 P1818 Pressure regulator 2

 

Do you think these are residual codes from earlier problems?  These codes don't show up under normal ODB-II interrogation. If I clear them to see if they return, would that reset my system readiness status? I have to get my car inspected in a few weeks and don't want to mess around with the readiness status.

I don't think either of those codes would result in the car failing emissions inspection.  I would wait until after the inspection then clear the codes and see if they come back.

P1671 OBD-II Diagnostic Powertrain (P) Trouble Code

Seems the codes are for the transmission, and not related to emissions.

Thanks.  I'll wait until after the inspection to clear them.
