2009 AUDI A4 PRESTIGE VIN WAUMK78K19N041602

This Audi A4 Prestige is a 2009 model, finished in black. The car runs on petrol. There is an automatic gearbox, with all-wheel drive. Every figure for this car is given as it appears in the source data.

A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

In the source data, the main issue is mechanical damage. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. Damage rarely stays where it is first seen: an impact can reach the mountings and airbags behind a panel, and water or fire the wiring and electronics.

A key is on file for the car.

The car carries a clean title. A clean title is a good sign, though it says nothing about wear, maintenance or how the car was driven.

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. A clean, polished car can still hide a serious accident, a flood or years of hard use.

On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating. Drive to all four wheels means more to maintain: differentials and couplings have oil of their own, which some manufacturers want changed at set intervals.

A vehicle identification number has 17 characters: the first three name the manufacturer, the next six describe the model and its specification, and the last eight identify the individual car. The VIN of this Audi A4 Prestige is WAUMK78K19N041602. The VIN usually appears at the base of the windscreen, on a door pillar and stamped into the body, and all of them should match the documents.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. Before going any further with this Audi A4 Prestige, it makes sense to look up VIN WAUMK78K19N041602.
