VCDS ABS Pump Test: Insights from Ross-Tech Forums

A manual transmission vehicle consistently displays an automatic transmission error within the EPB module. This issue arose during a recent taxi inspection, causing the vehicle to fail. The car has passed previous inspections despite this error being present for two years. The vehicle’s history includes a prior accident and insurance total loss, suggesting potential wiring modifications or module replacements performed during a private repair. The ABS module wiring exhibits signs of tampering, raising concerns about its integrity and potential contribution to the problem. While the EPB functions correctly and brake caliper operation is normal, the persistent error message needs resolution for re-inspection compliance. Previous Passat models required ABS module coding to specify brake, engine, and transmission configurations using PR codes. This raises the question of whether similar coding procedures apply to this vehicle and if incorrect coding might be the root cause of the error. Clarification on ABS coding procedures and potential solutions are sought to rectify the issue. The immediate goal is to eliminate the error message and ensure the vehicle passes its upcoming re-inspection.
