P0571 on Volkswagen: How to Diagnose & Fix
Cruise Control/Brake Switch "A" Circuit Malfunction

P0571 on Volkswagen by model: symptoms, diagnosis and fix
The brake light switch at the pedal can malfunction internally or be installed or adjusted wrongly. The brake lights may then stop working or stay on permanently, even when parked, which can drain the battery. On automatics the shifter may refuse to leave Park because the brake signal never arrives. The ECU cross-checks the two brake-switch circuits, so an implausible signal lights the EPC lamp, disables cruise control and stores a brake-switch code. Recall 03V265 (VW WT) had dealers inspect and replace the switch. Because a switch installed incorrectly during 03V265 or 04V096 could malfunction, follow-up recall 06V183 (VW N4, launched November 2006) has dealers install a newly designed brake light switch. Recall N4 applies to certain 1998–2002 New Beetles (A4/PQ34) with cruise control; confirm eligibility by VIN with Volkswagen. Cars outside the campaign with these symptoms still need diagnosis.
Common Symptoms
- Brake lights do not work
- Brake lights stay on with the car parked, draining the battery
- EPC warning light on
- Cruise control inoperative
- Automatic won't shift out of Park
How to Fix
Free recall remedy: under follow-up recall 06V183 (VW N4), dealers install a newly designed brake light switch at no charge. Check the VIN first. If no recall is open, the switch fits into the pedal bracket; it must be installed and adjusted correctly or the fault returns. After replacing it, clear the code and confirm the lights, EPC lamp and cruise all work. Also rule out a blown brake-lamp bulb before blaming the switch.
