Audi 90 FAQs
Check out real-world situations relating to the Audi here, particularly what our experts have to say about them.
Does the Audi A3 have Apple CarPlay & Android Auto?
All Audi A3 variants in the current Audi Australia line-up feature both Apple CarPlay and Android Auto connectivity. Audi A3 Apple CarPlay works wirelessly, while the Android Auto Audi A3 fitment still requires a cable to connect.
Some owners like to upgrade their car’s stereo and, in that case, the advice would be to go for a head unit that allowed wireless Android Auto as a worthwhile improvement.
The Audi system is not a simple retrofit to older Audi models thanks to the high degree of integration within the car’s controls and the system itself. That’s not to say it couldn’t be done, but it would probably not be cost effective compared with an aftermarket unit for an older car that still offered the desired functions.Show more
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.Show more
Are the engine internals the same in the 2.0-litre turbos from Audi, VW and Skoda?
You’re right, there’s a lot of commonality between the various engines from Skoda, VW and Audi. There are many examples of engines from these brands that all use the same basic bottom-end (crankshaft and pistons) architecture. And yes, in some cases, the main differentiator is the turbo-boost pressure.
But that doesn’t mean that’s the only difference; differing boost levels require different engine management, so the electronic control of the various engines can be very different. There can also be hardware differences such as the actual turbocharger unit and fuel injectors. That’s why it’s not quite as simple as raising boost pressure to arrive at a higher output. Revising engine management to do this requires somebody who really knows what they’re doing. Even then, a moderately powered version of an engine might not have the oil-cooling or strengthened internals of what appears to be the same engine with a higher output.
The VW-Audi group is not the only manufacturer to take this approach, of course, and many other car-makers use the same strategy of producing a variety of different engine tunes from the one basic unit. It’s a great way of differentiating models within a range and, of course, saving money in terms of research and development.Show more
