About this file

Description

VW GOLF PCR2.1 03L997557 M 03L906023A 03L997557M 9978 DUMP is an original (stock) ECU file for the VW GOLF CAYC fitted with the PCR2.1 engine control unit. It matches hardware number 03L997557M and software number 03L997557M 9978. The file was read with FLEX and is supplied exactly as read from the unit, byte for byte.

Typical use: restoring a damaged or corrupted ECU to factory software, recovering after a failed flash, or as a clean base before any modification. Before writing the file, confirm that the hardware and software numbers printed on your ECU label match the numbers above; writing a file to a unit with different numbers can damage the ECU.

After secure checkout the file is available for instant download from your AutoECUFile account, and it stays there for later downloads. Need another version of 03L997557M 9978, or a file that is not listed? Send us a file request and we will source it for you.
