Used Audi A4 cars for sale

Audi A4 buying guide

About the Audi A4

There are two different versions of A4 models – a four-door saloon, and a five-door Avant estate. Both options have plenty of passenger space, while the Avant slightly takes the edge for boot space.

If you’re shopping for used Audi A4 models, you’re likely to come across pre and post-facelift versions of the current car. Pre-facelift cars first went on sale in 2016 and carried on until the end of 2019. Used A4 models built from 2020 onwards got a few minor styling and technology updates to keep them feeling fresh.

What versions of the Audi A4 are there?

The entry-level trim for A4 models is called Technik, borrowing its name from the brand’s “Vorsprung durch Technik” mantra. This trim replaced the older SE version. Sport is the next step up and adds larger alloy wheels, a slightly more aggressive body kit and leather sports seats up front.

S Line is Audi’s even sportier trim and competes with Mercedes’ AMG-Line and BMW’s M Sport. At the top of the range sits Black Edition.

A popular option is Audi's Comfort & Sound pack, which adds keyless entry, a 360-degree parking camera and a brilliant Bang & Olufsen sound system. It typically increases the resale value of a car where it's fitted.

What features does the Audi A4 have?

Audi has long been known for building excellent cabins and the A4's doesn’t disappoint. Audi’s infotainment system is one of the best in the industry, with all the functions you’d expect and an intuitive, responsive interface. All post-facelift versions get Apple CarPlay and Android Auto as standard so you can easily and safely interact with your smartphone on the move. A digital instrument cluster – again, one of our favourites – is also standard on new-shape cars.

While it’s no van, the A4 makes a great practical choice for family buyers. The interior is large enough for five adults, and there’s enough room in the back seats to manoeuvre awkwardly shaped child seats into position. Boot space is strong on both the saloon and Avant estate models but the latter is a better choice for carrying dogs or bulky cargo.

Is the Audi A4 a good car?

The A4 looks and feels premium both inside and out, comes packed with tech, and is effortless to drive so, yes, we think it's a pretty great car.

If you're looking for a used A4, you'll probably be cross-shopping it against an equivalent BMW 3 Series or Mercedes C-Class. For us, we think the BMW is sportier but a little less comfortable, while the Mercedes is softer at the expense of handling, so the Audi represents a neat middle ground between the two – a great all rounder that's easy to drive no matter the situation.

Audi A4 engine range explained

Audi A4 35 TFSI petrol

The entry-level petrol choice for the A4 is the 35 TFSI. This is a 2.0-litre turbo four-cylinder with 150hp, which can complete the 0-62mph sprint in under nine seconds. Average economy can rise as high as 47mpg if you drive gently.

Audi A4 40 TFSI petrol

If you’re looking for a little more punch from your A4’s engine, check out the 40 TFSI option. This turns up the boost on the 2.0-litre engine to 190hp, dropping the 0-62mph time to less than eight seconds. Later cars have 204hp and a 0-62mph time of slightly over seven seconds.

Audi A4 30 TDI diesel

A4s have long been a favoured weapon of choice for high-mileage drivers, with the 2.0-litre diesel engine choices remaining a popular choice for several generations. The entry-level 30 TDI makes 136hp, which can still accelerate this model to 62mph from rest in less than 10 seconds. Average economy can crest 65mpg if you drive with a light foot.

Audi A4 35 TDI diesel

Most diesel A4s come equipped with the 35 TDI engine option. This boosts power to 163hp, dropping the 0-62mph time down to less than nine seconds. Average economy stands at around 60mpg if you can resist using the extra power.

Audi A4 40 TDI diesel

For buyers that want the long-legged range of a diesel but crave a little power under their right foot, the 40 TDI option might be just right. Here, the 2.0-litre diesel makes a strong 204hp, which is enough to get the 40 TDI to 62mph from rest in around seven seconds.

Audi A4 S4 TDI diesel

The king of the hill among A4s is the S4 TDI. This wades into battle with a mighty 3.0-litre turbodiesel six-cylinder engine making nearly 350hp. Combined with the standard automatic gearbox and quattro all-wheel drive, the S4 TDI sprints from 0-62mph in just 4.8 seconds – just a stone’s throw from the kind of performance you’d expect from an out-and-out supercar.
