My MAF plug wires are PIN 1 - blank, PIN 2 - black/light blue, PIN 3 - yellow/brown, PIN 4 - purple, PIN 5 - green/brown. I checked the harness side of the MAF plug to determine which wires go to the IAT sensor, but my wire colors do not match Bentley manual (this car was built in November 2006 - late production). Fault code reads P0113, but just want to ensure that it is the MAF before I replace it if possible. Turbo now somewhat works at higher RPM, but no/low power at low RPM. Used my brake bleeder on the vacuum port of the N75 and watched the rod work with vacuum applied. Cleaned MAF sensor, cleaned grounds, looked at wires (even removed plastic covers at plugs) including peeling back the looms, checked vacuum lines, but nothing obvious to me. Replaced Boost Pressure Sensor and cruise works now, but still no power. Went to Autozone, ran test and came back with code P0236. Here's how I got here: Noticed cruise control did not work one morning, and then immediately noticed no power. New user, first post, just purchased VCDS to identify codes and obtain assistance in this respected forum.
