Diagnose the fault. Not just the code.
Specialist DSG and S tronic diagnosis for Volkswagen, Audi, Skoda, SEAT and CUPRA, with selected other dual-clutch transmission enquiries. We test hydraulic, electrical, pressure-control and clutch-control faults before recommending repair or replacement.
Pressure actual: 31.8 bar
Status: PRESSURE LOSS
Start with the vehicle. Then identify the transmission.
The same model can use different DSG families depending on engine, build date and drivetrain. This finder gives the common families, then we confirm the exact unit before quoting parts.
Find your DSG / dual-clutch platform
Select the make and model for a guide to the transmission families commonly fitted. Exact fitment is confirmed from VIN and transmission code before parts are quoted.
Fitment guide only. A model name does not guarantee a particular gearbox. Engine, build date, drivetrain and market can change the transmission fitted.
Specialist pages for the vehicles that use them.
DSG is Volkswagen Group terminology. Audi commonly uses the S tronic name. Other manufacturers use their own dual-clutch systems, which are listed separately rather than incorrectly calling them DSG.

A dual-clutch 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.
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 pump, accumulator, pressure leakage and internal hydraulic faults.
Mechatronic Replacement
Correct unit identification followed by required coding, basic settings, adaptation and road testing where applicable.
Repair Assessment
Assessment of whether a mechatronic repair is technically appropriate versus full replacement.
Clutch & Adaptation Analysis
Clutch travel, bite point, temperature and adaptation data assessed to separate mechatronic faults from clutch-pack concerns.
Post-Repair Setup
Correct scan-tool procedures, coding, basic settings and relearn processes after relevant DSG repairs.
Core DSG mechatronic platforms.
Different DSG families have different clutch systems, control architecture and failure patterns. Correct 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.
Model-specific DSG & S tronic guides.
Dedicated pages now cover the most common Volkswagen Group models we see, with transmission-family guidance, common symptoms and the diagnostic process for each vehicle.
Brand-specific and technical DSG guides.
The theme now seeds a full set of SEO articles covering Volkswagen, Audi S tronic, Skoda, SEAT, CUPRA and the major DSG fault patterns.
How DSG Transmission Identification Works
Why VIN, transmission code, engine and drivetrain information are used together to identify the correct gearbox family.
After a DSG Repair: Recheck & Verification
Why post-repair scanning, adaptations, road testing and leak/pressure verification matter before the job is considered complete.
Used DSG Mechatronic Units: What to Consider
Compatibility, software, coding, adaptation and unknown history can all affect a used mechatronic replacement.
DSG Service vs DSG Repair
Routine fluid/filter servicing and fault diagnosis are different jobs. Here is what each is designed to achieve.
DSG Fault Codes: Why Codes Need Testing
Why diagnostic trouble codes identify an affected system but rarely prove which physical component must be replaced.
DSG No Drive: Where Diagnosis Starts
The checks used when a vehicle selects a gear but does not move, or intermittently loses drive.
DSG Loss of Even Gears
Why one clutch or selector path can drop out and the diagnostic checks used to separate possible causes.
DSG Loss of Odd Gears
How a dual-clutch transmission can lose one gear path and what the fault pattern can tell us.
DSG Harsh Shifting
Why harsh shifts can come from adaptation, hydraulic control, mechatronic faults, clutch condition or mechanical wear.
