2018 AUDI S4 PREMIUM PLUS VIN WAUB4AF4XJA003929

The Audi S4 Premium Plus described here left the factory in 2018. The gearbox is automatic. Power comes from a 3.0-litre petrol engine with six cylinders, rated at 354 hp. Every figure for this car is given as it appears in the source data.

At the time of recording, the car had covered 72,774 miles. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. The number on the clock proves little by itself; earlier figures logged at services and inspections are what make it believable. Title paperwork often notes the mileage at each change of owner, which makes it a useful cross-check.

In the source data, the main issue is minor dents and scratches. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since. Some damage shows its consequences only later: corroded connectors and electrical faults can surface months afterwards.

A key is on file for the car. Months of standing can leave a car with seized brakes and perished tyres.

According to the source data, the car has 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 is the sum of what has happened to it since it was new, and most of it has left a trace on paper somewhere. From the outside, a car with a repaired accident and a car without one can look identical.

For the engine, the service history matters most: oil changes, filters and the timing belt or chain are the entries to look for. 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.

A VIN never contains the letters I, O or Q, which could be mistaken for digits; its 17 characters identify the maker, the model and the individual car. The VIN of this Audi S4 Premium Plus is WAUB4AF4XJA003929. 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.

What a history report can list depends on what has been documented about the car: registrations, mileage readings, damage, branded titles and theft reports. Paperwork is only as complete as the people who kept it, so a report with few entries lowers the risk without removing it. 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.
