New Car PDI Scope: 250+ Checkpoint Deep Dive
Automakers ship vehicles thousands of kilometers by open trailer. Scratches happen, panels get repainted at dealer body shops without your knowledge, and electronics stay dormant in wet yards. We categorize our 250+ checkpoints across 7 core disciplines:
Metrology & Paint Thickness
Every metal and composite panel is probed with magnetic/ultrasonic gauges to benchmark factory clearcoat versus non-OEM repaint or bondo body filler.
- check_circle12-Panel Micron depth measurement (80-130µm OEM baseline)
- check_circleDetection of transit stone chips, buffing swirl marks & overspray
- check_circleDigital Vernier caliper door and bonnet shutline tolerance audit
Powertrain & Engine Bay
Thermal, static and dynamic examination of engine seals, auxiliary belts, plumbing clamp torques, and reservoir fluid health.
- check_circleEngine oil viscosity, coolant glycol concentration & brake fluid boil point
- check_circleRodent bite inspection across secondary harness looms and vacuum tubes
- check_circleCold crank RPM stability, alternator belt tension and pulley alignment
Underbody & Chassis
Full crawler and mirror inspection of floorboards, suspension linkages, brake lines, and anti-rust zinc coatings.
- check_circleUnloading ramp scrape inspection on front subframe and floorpan
- check_circleSuspension strut dampening fluid leak & spring isolator seating
- check_circleExhaust catalytic converter mounting bracket and heat-shield rigidity
Electrical & OBD-II Scanner
Computerized scan hooked up to OEM diagnostic port checking all vehicle control modules for hidden shadow error codes.
- check_circleEngine, Transmission, ABS/ESP and Airbag (SRS) live stream readouts
- check_circleBattery Health: State of Charge (SOC) & cranking drop voltage
- check_circleADAS camera and forward radar sensor alignment validation
Cabin Fit, Finish & HVAC
Detailed touch, test, and laser probe audit of all interior upholstery, electronic accessories, climate cooling and motorized sunroofs.
- check_circleDigital HVAC temperature differential test at dash vent louvers
- check_circleSunroof track grease, water drainage channel & anti-pinch function
- check_circleInfotainment display dead-pixel inspection and speaker balance
Glass Monogram, Tyres & VIN Form 22
Document and date triangulation to prevent dealers from pushing older stock or replaced windshields due to transport breakage.
- check_circleTriangulation of 6+ glass monograms to ensure factory batch continuity
- check_circleAll 5 Tyre DOT week & year stampings verified against car assembly date
- check_circleChassis metal punch, windshield tag vs. OEM Form 22 Certificate
Used Car Comprehensive Scope: Forensic Verification
Buying pre-owned comes with distinct hazards: structural apron cuts, concealed flood submergence, rolled-back odometers, and slipping gearboxes. Our forensic package safeguards your hard-earned money.
Major Accident & Structural Pillar Cuts
We inspect spot welds, apron sealants, crumple-zone deformation, and A/B/C pillar structural integrity to catch repaired roll-overs or heavy collisions.
- • Running board & rocker panel weld seam scrutiny
- • Front radiator core support replacement flags
- • Boot-floor ripple & non-OEM seam sealant detection
Concealed Flood & Water Submergence
Flooded cars are dried, perfumed and resold. We find telltale microscopic silt, seat-rail rust, under-carpet mildew, and ECU pin corrosion.
- • Seat-belt full spool extraction for flood watermarks
- • Rust inspection on pedal assembly brackets
- • Fuse box corrosion & behind-glovebox mud residue
Odometer Forensic & Mechanical Wear
Digital meter tampering is rampant. We triangulate dashboard odometer numbers with ABS wheel sensor logs and Transmission Control Unit run-hours.
- • TCU/ABS module mileage parity validation
- • Engine blow-by & cylinder compression estimation
- • Automatic gearbox torque-converter slippage check
250+ Inspection Parameters: Method, Threshold & Severity
Below is an indicative excerpt of our technical checklist standard used on every PDI assignment. Each point carries an explicit tolerance threshold and severity score.
