Coding Engine Control Module (A4, A6 & S4)
Connect VAS 5051 or equivalent scan tool to Data Link Connector (DLC). DLC is located behind cover under left side of steering column. Turn ignition on. On scan tool, select vehicle system 01 - ENGINE ELECTRONICS. From selection 1, select diagnostic function 07 - CODE CONTROL MODULE. Press "Q" button to confirm input. Following scan tool instructions, access ECM coding information. Enter ECM code as necessary. For ECM coding options, see ENGINE CONTROL MODULE CODING OPTIONS (A4) or ENGINE CONTROL MODULE CODING OPTIONS (A6) table.
As an example, a properly coded ECM for an A4 model with Front Wheel Drive (FWD) with traction control (ASR/ESP) and 5-speed automatic transmission would read 16501 on the VAS 0551 scan tool.
