2005 AUDI A4 2.0T QUATTRO VIN WAUDF68E25A481077

This Audi A4 2.0T Quattro was built in 2005. There is an automatic gearbox, with all-wheel drive. Power comes from a 2.0-litre petrol engine with four cylinders. The specification is taken from the source data.

The record gives the mileage as 152,723 miles. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

When the car was recorded, it showed front-end damage. Two cars with the same damage label can be very different: one needs a few new parts, the other major work.

A key was noted with the car. Condition notes are a snapshot: the car may have been worked on, stripped of parts or left standing since.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. A car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

A cold start, the colour of the exhaust smoke and any oil leaks tell a mechanic a good deal about how an engine has been treated. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. Automatic transmissions, CVTs included, are expensive to repair, so the test drive should include pulling away from a standstill and a stretch at motorway speed. A car with all-wheel drive has extra differentials and often a transfer case, which an inspection should cover alongside the engine and gearbox.

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. This Audi A4 2.0T Quattro has the VIN WAUDF68E25A481077. 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.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. 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. A history check on VIN WAUDF68E25A481077 is the place to start.
