Overview

Oil Pressure Fix 0.4 is a file-based utility for ECU calibration specialists working with selected Bosch MD1CS004 and MD1CP004 firmware used in VAG applications.

It locates patch areas through context-aware pattern scanning instead of fixed addresses. Existing firmware files can be loaded through drag and drop or a file selector, processed with the designated oil-pressure-control patch and reviewed through the operation log.

Compatibility depends on the exact software identifier and binary layout. A complete supported-version list is not available; ECU-family membership alone does not confirm support.

This is an offline file editor, not an OBD diagnostic or read/write interface. A separate compatible ECU programmer is required. Retain the untouched original and validate the output and required checksums before programming.

The patch does not repair mechanical oil-pressure faults and must not conceal a genuine low-oil-pressure condition.
