Pre-Delivery Inspection (PDI) refers to the final comprehensive quality check and feature activation carried out by authorised dealership technicians according to manufacturer standards before a brand-new vehicle is handed over to its owner. It is essentially a comprehensive "health check" for a new car—systematically ensuring that no damage was sustained from the factory floor through transit and storage, while switching the vehicle out of transport mode into normal operating mode. For car buyers, the PDI checklist serves as official proof of the car's pristine handover condition and a vital document for future warranty and consumer claims.
1. Why a PDI Is Absolutely Crucial
Between rolling off the assembly line and reaching the showroom floor, a new car undergoes long-distance transport and weeks or even months of storage. Hidden issues like paintwork scratches or undercarriage scrapes can happen along the way, while extended storage can cause battery drain and tyre pressure loss. Crucially, new cars leave the factory with "Transport Mode" enabled for safety—limiting speeds to between 30 and 80 km/h, while disabling features like navigation, air conditioning, and active safety systems. Failing to deactivate this mode via PDI leaves the vehicle functionally restricted, and driving it under these conditions could damage key components and compromise road safety.
The PDI process is designed precisely to rectify these issues, activate all electronic systems, and generate a VIN-matched inspection record to ensure the car delivered meets the manufacturer's operational standards.
2. Core Checkpoints of a PDI
A thorough PDI typically covers the following four main areas:
| Category | Core Inspection Scope |
|---|---|
| Exterior & Bodywork | Paint flaws and colour mismatches (some marques inspect 50+ points with a paint depth gauge), verifying manufacturing dates on windscreen/windows and tyres, panel gap alignment, and setting tyre pressures to spec |
| Engine Bay | 12V battery health, fluid level checks (engine oil, brake fluid, coolant), and inspecting wiring harnesses and hoses for chafing or damage |
| Undercarriage | Lifting the car to inspect for underbody scrapes, engine/gearbox oil leaks, torque marking alignments on bolts (to check for tampering), and high-voltage battery casing integrity (for electrified vehicles/EVs) |
| Electronics & Road Test | Deactivating transport mode to enable all onboard electronics; checking cold-start idling smoothness; testing the air-con, lighting, audio, and head unit/infotainment; short test drive to assess transmission smoothness, steering alignment, and braking response |
The number of checkpoints varies between marques; for instance, VOYAH uses an 8-category, 88-point PDI checklist, whereas mainstream brands typically inspect over 40 items. Once finished, a formal "PDI Checklist" is produced, detailing the status of every single item.
3. Buyer Rights and Practical Advice for PDI
1. PDI is 100% Free of Charge
Carrying out the PDI is a dealer obligation, with the cost fully subsidised by the principal manufacturer. Any attempt by a salesperson to charge a "PDI fee" is completely unjustified.
2. Be Present If Possible
While most 3S/4S centres run a preliminary check upon receiving stock, buyers have the right to observe the final PDI before handover. Being there in person ensures the technician takes extra care and helps catch any defects on the spot.
3. Demand and Verify the Inspection Sheet
During collection, always ask for the original PDI checklist stamped with the dealership's official chop (or at least snap a clear photo), cross-check the chassis number (VIN) against your vehicle, and verify the mileage (typically ≤50 km). Once you sign off on the delivery form, you are accepting the car as-is, making it extremely difficult to hold the dealer liable for cosmetic issues like paint chips discovered later.
4. Address Defects Immediately
If any cosmetic defects, malfunction, or fault codes turn up during the check, raise them with your sales advisor on the spot. Minor flaws should be rectified with goodwill compensation; for major issues (like gearbox faults or structural defects), you are fully entitled to request a replacement unit.
4. Cautionary Real-World Cases
In 2019, a newly delivered Li Auto model suffered an acceleration cutout right after entering the expressway because the handover team forgot to deactivate "Logistics Mode" during PDI, crippling vehicle power at cruising speeds. Founder Li Xiang later publicly acknowledged the oversight in their PDI protocol. This incident highlights that PDI omissions do not just ruin the ownership experience—they pose severe, immediate safety risks on the road. Similarly, the high-profile "Xi'an Mercedes-Benz bonnet protest" stemmed from a careless dealership PDI that overlooked a serious pre-existing defect before handover.
Ultimately, the PDI is the final and most crucial quality control barrier before taking delivery of a brand-new car. It is both a dealer's duty and a buyer's right. Insisting on witnessing the PDI, checking the report thoroughly, and keeping a copy on file upon collection are essential to protecting your interests and avoiding being handed a "lemon" from day one.
