2016 AUDI A6 PREMIUM PLUS VIN WAUFGAFC5GN021448

This Audi A6 Premium Plus is a 2016 model, finished in black. The engine is a 3.0-litre petrol unit with six cylinders. Power reaches the wheels through an automatic gearbox.

The recorded mileage is 194,062 miles. The mileage is high for the car’s age, so the suspension, brakes, seats and steering wheel deserve a close look. Gaps of several years between logged figures deserve attention, as does any reading lower than the one before it. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

In the source data, the main issue is mechanical damage. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since. Whatever the cause, a diagnostic scan of the car’s electronics shows fault codes that a visual check misses.

A ‘runs and drives’ note means the car moved under its own power when it was checked. A key is on file for the car. Running condition describes a single moment, and standing or work done since can change it.

A clean title is on file for this car. A clean title is a good sign, though it says nothing about wear, maintenance or how the car was driven.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

For the engine, the service history matters most: oil changes, filters and the timing belt or chain are the entries to look for. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. 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.

The ninth character of the VIN is a check digit calculated from the other sixteen, so a mistyped or invented number does not add up. This car’s identification number is WAUFGAFC5GN021448. The number in the car’s documents should match the one stamped into the body and the one on the plate at the base of the windscreen.

What a history report can list depends on what has been documented about the car: registrations, mileage readings, damage, branded titles and theft reports. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. A VIN check and a physical inspection answer different questions: the first says what happened to the car, the second what condition it is in now.
