Diagnose the fault. Not just the code.
Specialist testing and repair pathways for Volkswagen Group DSG mechatronic systems. We diagnose hydraulic, electrical, pressure-control and clutch-control faults before recommending repair or replacement.
Pressure actual: 31.8 bar
Status: PRESSURE LOSS
Mechatronic work built around proper diagnosis.
A DSG fault can originate in hydraulic pressure control, solenoids, internal electronics, speed or position sensing, clutch adaptation, wiring, power supply or mechanical transmission faults. We test the system before deciding the repair path.
DSG Mechatronic Diagnosis
Full fault-code interrogation, measured values, actuator checks, hydraulic pressure behaviour, clutch data and electrical supply checks.
Hydraulic Pressure Testing
Where applicable we perform controlled pressure testing to confirm accumulator, pump, pressure leakage and internal hydraulic faults.
Mechatronic Replacement
Replacement pathways using suitable genuine or approved units, followed by coding, basic settings, adaptation and road testing where required.
Mechatronic Repair Assessment
Assessment of whether a repair is technically appropriate versus full replacement, based on fault pattern and internal condition.
Clutch & Adaptation Analysis
Clutch travel, bite point, temperature and adaptation data assessed to separate mechatronic faults from clutch-pack problems.
Post-Repair Setup
Correct scan-tool procedures, coding, basic settings and relearn processes carried out after relevant DSG repairs.
Common DSG mechatronic platforms we diagnose.
Different DSG families have very different failure patterns. Correct gearbox identification matters before parts are quoted or ordered.
From symptoms to an evidence-based repair plan.
We do not use a “scan and quote complete replacement” approach. The vehicle is assessed as a system so the recommended repair matches the actual failure.
Fault history & symptom confirmation
Review warning messages, drivability symptoms, prior repairs and when the fault occurs.
Full DSG & vehicle scan
Capture DTCs, freeze-frame information and related vehicle-system faults.
Measured values & hydraulic behaviour
Assess pressure control, clutch position, temperature, sensor data and relevant actuator response.
Electrical & mechanical checks
Where indicated, test supply voltage, grounds, wiring, connectors and transmission condition.
Repair recommendation
Only after diagnosis do we recommend repair, replacement, clutch work or further mechanical testing.
