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 Nexon 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.
For the relevant engine, confirm suitable oil, oil filter, air filtration, fuel-system filtration and coolant. Petrol ignition components such as spark plugs and coils differ from diesel injection and applicable glow components. Factory-CNG servicing needs trained handling and the correct gas-system guidance. Belts, engine mounts, seals and sensors are inspected as appropriate; they are not a compulsory bundle for every Nexon visit.
Poor acceleration can have intake, fuelling, ignition, sensor or transmission-related explanations. On turbocharged versions, relevant connections and supporting components may also need assessment. Tell CarTech Hub when the symptom happens and which warnings appear. Major engine repairs or an overhaul require findings that justify the scope, not just a stored code.
Radiator, water pump, coolant hoses, fan and thermostat checks are important when temperature behaviour changes. Do not open a hot cooling system or continue driving with a serious temperature warning. A diesel's applicable emission-system warning should be assessed under its correct manufacturer guidance; deleting emission equipment or guessing a reset is not a responsible repair plan.
Pads, discs, rear braking components as fitted, brake fluid and ABS data are considered for a brake complaint. Steering changes or uneven tyre wear can lead to checks of lower arms, ball joints, stabiliser links, bushes, struts, shock absorbers and wheel bearings as applicable. Loose or damaged components need repair before an alignment is used to finish the job.
For AC service, distinguish compressor or refrigerant-circuit issues from cabin filter or blower concerns. Electrical assessment can involve battery health, charging, starter operation, wiring, fuses, relays and sensors. Parts are ordered after fitment and fault confirmation. A sensor-equipped variant can also require procedures unavailable in a simple general scan, so confirm the workshop's capability first.
The fitted system changes the investigation: manual clutch actuation and friction parts, AMT controls and actuators, and DCA-specific procedures are separate considerations. Supply the exact transmission details so fluid, mounts, seals and driveshaft findings can be interpreted against the correct arrangement.
