    Audi A4 Review, For Sale, Colours, Interior, Specs & News

    The mid-sized Audi A4 dates back to 1994, and is one of the mainstays of the German luxury brand's line.

    Its main rivals are other mid-sized luxury cars like the BMW 3 Series and Mercedes-Benz C-Class. An all-new A4, known as the B9, launched worldwide in 2016, and includes a four-door sedan, four-door Avant wagon and a two-door convertible. Prices start at $55,900 for the A4 35 Tfsi Mhev up to $74,900 for the A4 Allroad 45 Tfsi Quattro Mhev.

    The A4 is powered by an array of turbocharged petrol and diesel engines and can be had in both front- and all-wheel drive variants. It's also spawned offshoots like the A5 coupe, the S4 sports sedan and wagon and the potent RS4.

    Audi A4 Q&As

    Check out real-world situations relating to the Audi A4 here, particularly what our experts have to say about them.

    • My recently purchased Audi A4's due for an oil change. Can you advise on the right formula and the key steps I should follow?

      Audi A4 engine oil changes are a critical part of life for this car, as its high-tech engine is complex and precise and will not tolerate dirty or old oil. But even though the engine is sophisticated, as long as you know how to change the oil correctly, it’s a great DIY way to save money for the home mechanic (oil changes are a major income source for the average service centre) and will empower you to tackle more maintenance jobs including, perhaps, a full service. The best advice is to buy a workshop manual and follow exactly the steps as laid out, but essentially, you’ll need to drain the old oil, replace the oil filter, renew the oil and dispose of the old oil in an environmentally acceptable way (many councils operate oil recycling stations). While not a challenging job for a mechanic, the Audi is a complicated machine with lots of components competing for space, so it’s possibly not a job for the completely uninitiated.

      There are several things you need to know before even reaching for a spanner. Those include the type of Audi A4 oil you need, the specifications of the Audi A4 oil filter that will be changed as part of the process, and how often to change oil (often referred to as the oil-change interval). You also need to know precisely what year your car is as Audi varied specifications as the years rolled by. A 2007 A4, for instance, may have different specifications compared with one from 2010, or 2013. Even a 2011 and a 2012 Audi A4 had differences under the bonnet, so be very specific when it comes time to buying the oil and replacement filter. Don’t forget, too, that the A4 has used extensively both 1.8 and 2.0 size engines and, of course, a diesel option which has its own set of specific requirements when it comes to servicing. Again, the workshop manual and the parts interpreter where you buy your oil and filter are your friends. Knowing your car’s VIN can also be a big help in identifying what specific parts you need.

      The correct Audi A4 oil type is (for petrol and diesel engines) a fully synthetic 5W30. You’ll need five litres for a diesel oil change and 5.2 litres for the petrol engine-A4. The correct replacement oil filter is a Ryco (or equivalent) R2748K for the petrol engine and an R2740P for the turbo-diesel.

    • What oil does a 2004 Audi A4 use in the engine?

      I’d go for a fully synthetic engine oil with a viscosity rating of 5W-40. The turbocharged 1.8-litre engine in that model is a pretty hard-working unit and quite a complex engine, so frequent oil changes are critical to its longevity. The brand of oil is not so important, provided you use a quality brand and not the Brand-X stuff sold at supermarkets and some online clearing houses. Don’t forget to change the oil filter at the same time; putting clean, fresh oil through an old, dirty filter makes no sense at all.

    • Audi A3 and A4 2010: Are they reliable?

      Volkswagen is very quick to point out that the earlier transmission woes with its DSG gearbox have been fixed. Certainly, the later versions seem to be better, but the jury is still out on whether the fix has been a complete one.

      In any case, that’s no use to you as the cars made around 2010 are, indeed, the ones that were most affected by these troublesome transmissions. The smaller Audi models were the main offenders as some of those used the dry-clutch version of the DSG. The larger (and heavier) A4 tended to have the wet-clutch version of the same gearbox which wasn’t nearly as problematic. So that should be your golden rule here if you decide to take the plunge: Only buy a second-hand Audi with a wet-clutch DSG. Even then, we can’t guarantee that it will be all sweetness and light, but at least you’re a chance to side-step major problems. Audi actually recalled many of its models to deal with these gearbox issues at the time.

      The other thing to be sure of is that any used Audi you buy has a complete service history with no gaps or late services. These cars use high-tech engines that absolutely require clean oil and filters at regular intervals. A neglected Audi is a very good chance to be a pain in the wallet down the track. Like many second-hand prestige cars, these Audis are often cheap for a reason.

    • Should I buy an Audi A3 or A4?

      It would pay to bear in mind, Tony that there’s an all-new A3 due in Europe next year (Check out Carsguide’s overage of the Geneva Motor Show when it happens) as well as a major upgrade of the A4 that will include new or comprehensively revised engines and mostly new body panels and interior.

      Is the heavily discounted A4 a dealership demonstrator? As that might explain why the A4, even though it’s the bigger car, has had its price slashed, despite having all that desirable kit thrown in. That said, the A4 lives in a market segment (mid-sized sedans) that is not doing terribly well right now (in Australia and elsewhere) so maybe Audi has too much stock of a car that has plenty of competition (Mercedes-Benz C-Class and BMW 3-Series) in a struggling market.

      The bottom line, however, is to buy as much car as you need and don’t make the mistake of buying a smaller, cheaper car when it won’t easily do the jobs you have in mind for it. Again, though, the A3 is a pretty practical hatchback (or sedan) and owners don’t seem to complain that it’s underdone in any major way.
      So, drive them both, and see which one you like to pilot. And then start throwing offers at the salesman and see how much he or she is able to bend on either car. By the way, the virtual cockpit is brilliant technology.

    Audi A4 Accessories

    In standard guise this allroad’s features list includes a new 10.1-inch touchscreen (with Apple CarPlay and Android Auto), DAB+ digital radio, an Audi 10-speaker stereo, wireless charging for Qi-enabled smartphones, Audi’s Virtual Cockpit (a 12.3-inch digital display), smart key with push-button start, leather trim, three-zone climate control, as well as LED headlights, 18-inch alloy wheels, illuminated door sills, and overall tweaked exterior and interior styling.

    It also has AEB with pedestrian detect, lane change warning, rear cross-traffic alert, front and rear parking sensors and a reversing camera.

    But our test vehicle has a few different features and a fair few extras. Our allroad has a ‘price as tested’ of $75,681 (plus on-road costs), because it has Assistance plus package ($2900), which includes a raft of driver-assist tech, such as adaptive cruise control, active lane assist, collision avoidance assist, high beam assist, head up display, park assist (helps to steer the vehicle into a parallel or perpendicular parking space), as well as a 360-degree-view cameras.

    It also has 19-inch Audi sport alloy wheels in 10-Y-spoke design ($1350), instead of the standard 18-inch alloy wheels in 5-V-spoke design, and metallic paint (Mahattan grey, $1531).

    Audi A4 Interior

    The allroad’s interior looks good and certainly feels open and spacious, although the driver’s seat tends to feel a bit more snug as the dash is angled towards that position.

    The new 10.1-inch touchscreen, home for most upfront functions, dominates the dash, in a good way.

    The front seats are electrically adjustable with lumbar and driver memory.

    There are plenty of places in which to put your everyday bits and pieces (including a decent storage bin/arm-rest), as well as charging points, including two USB ports, for your devices.

    Need somewhere to put a cold beverage, mate? There are two cup-holders between driver and front-seat passenger, two in the fold-down centre arm-rest for the back-seat passengers, and bottle holders in all doors.

    Back-seat passengers also get air vents, climate control, mesh seat-back pockets and grab handles. 

    There is a 495-litre cargo space when the rear seats are in use, but that increases to 1495 litres when those seats – 40:20:40 split folding – are stowed away in the floor.
