Tell us which warning light came on and what your car was doing at the time. We’ll confirm which scanner checks your vehicle supports, explain the findings and agree on the next step with you.
Diagnostic information updated 29 October 2026 · Independent multi-brand workshop
Tell us the vehicle’s year of manufacture, variant, engine or fuel type, and the exact warning message. Different versions of the Punch may have different control units and require different diagnostic access.

This is a model-specific enquiry page. The workshop can confirm which checks your model year and control system support.
CarTech Hub uses LAUNCH Scan Plus X and XTOOL Compass for scanner-assisted fault finding in Sawkuchi, Guwahati. Share your car’s make, model, year, fuel type and warning message so we can confirm the relevant scanner coverage before your visit.
Ask about a Scan Plus X check when reporting a warning light, starting problem or electronic-system concern. We first confirm communication with the relevant control unit and the diagnostic functions available for your vehicle.
The installed software, vehicle year, engine and control unit determine which checks are possible. Code reading, live-data checks and service functions are confirmed for the job before work begins.
LAUNCH official vehicle-coverage resource ↗XTOOL’s Compass information lists fault-code reading and clearing, live data, freeze-frame information, actuator tests and reports from scans before and after work. Availability depends on the vehicle and supported system.
We use the relevant information to investigate your complaint and explain the next check. XTOOL lists Compass and Compass Master configurations separately, so optional hardware and programming access are confirmed for each task.
XTOOL official Compass product information ↗We accept scanning enquiries for Indian, Japanese, Korean, European and other car brands. A brand or model listing does not confirm access to every control unit. The vehicle’s ECU, software version, licence, security access and any required accessories affect the work we can accept.
Ask separately about service resets, adaptations, coding, programming, ADAS calibration or EV high-voltage work. These need the right equipment and procedures; they are not automatically part of a basic scan. A fault code helps direct an investigation and does not by itself prove which part needs replacing.

CarTech Hub first records the warning and the driving conditions in which it appeared. On supported vehicles, the technician reads the engine, ABS or airbag control module and checks whether its fault codes are current or stored. For an engine complaint, freeze-frame data and sensor readings can show the engine’s operating conditions when the fault occurred. For ABS, individual wheel-speed readings can help isolate an inconsistent signal. An airbag warning calls for a restraint-system assessment using the manufacturer’s procedures. The technician explains any further tests and discusses the repair estimate with you before you approve the work.
A fault code is one clue. The technician compares it with the symptoms you describe and the condition of the vehicle before recommending further checks.
Share the vehicle details, warning message, recent work and the conditions in which the issue appears.
We check whether the scanner supports the system you want tested and agree with you on what the initial assessment will cover.
Available codes and data guide further electrical or mechanical checks. A stored code alone does not justify replacing a part.
Discuss what is confirmed, what still needs testing and the estimate before approving further work.
Where appropriate, repeat relevant checks and review the original complaint. Clearing the warning light alone is not a completed diagnosis.
The directory has 765 model entries across 36 brands, including earlier generations and variants. Choose your car and tell us its model year, fuel type, variant and warning message. The workshop will confirm which control units it can check and which repairs it can undertake.

Coverage depends on the model year, control unit, software and access requirements. Tell us the symptoms or warning message so we can check whether the relevant function is supported before you visit.
A code records a condition detected by the car. A technician may need to inspect wiring, power supply, mechanical components or operating conditions before recommending a replacement.
Programming and calibration are separate jobs. Before booking, ask what hardware and software access the work requires, whether a trained technician is available and what the work would cost for your vehicle.
Bring your vehicle details, a description of the symptoms, relevant service records and any earlier scan report. Tell us about recent battery work and whether anyone cleared the fault codes.
Applicable engine oil and oil filter, air filtration and fuel-system parts are chosen for the actual engine. Spark plugs and ignition components can be relevant to petrol and iCNG combustion operation; injectors and gas-system hardware are not ordered by badge alone. Engine mounts, belts, sensors and cooling components deserve inspection when the schedule or complaint calls for it. Never treat CNG lines or cylinder hardware as a casual home repair.
Manual clutch concerns can lead to checks of the actuation and correctly matched clutch plate, pressure plate and release bearing. On an AMT, supply voltage, faults, actuator operation and any required calibration are considered alongside mechanical condition. A shift warning does not prove the gearbox must be replaced. CarTech Hub should explain the available transmission diagnostic scope for your Punch.
Brake pads, discs, fitted rear components, fluid and ABS-related information also require examination if braking changes. A warning can arise from different causes, including sensor or wiring damage, so the estimate should identify the finding rather than add a complete brake overhaul by default.
In humid Guwahati traffic, distinguish low airflow from poor cooling. Cabin filter, blower operation, condenser condition, compressor control and leak diagnosis answer different AC questions. A refrigerant top-up without identifying a leak may leave the original concern unresolved. The engine cooling fan also has its own role and should not be confused with the cabin blower.
Battery condition, charging output and cable connections are sensible starting points for an intermittent start. Alternator, starter motor, fuses, relays, switches, sensors and wiring are considered where the tests lead. Electrical repair information explains why fault finding should precede expensive assembly replacement.
A wheel that looks round can still need competent assessment. The impacted tyre, rim, bearing and relevant steering or suspension parts should be checked, with damage or looseness addressed before alignment; a photograph cannot establish that the affected corner is safe.
