The Audi A4 is a premium saloon that goes toe-to-toe with the BMW 3 Series, Mercedes C-Class, and Jaguar XE. Exceptional cruising refinement, impressive interior build quality and a generous standard kit are all major pluses. The latter includes Audi's superb Virtual Cockpit digital driver's display, along with a slick 10.1-inch touchscreen for controlling infotainment. The relatively frugal engine line-up includes petrol and diesel models with a 2.0-litre capacity and varying power outputs, but as yet, no plug-in hybrid model. It's available with two- or four-wheel drive, although the quattro models are expensive, and is offered in Sport, S line, and Black Edition trim levels. It's a polished all-rounder that has few flaws. Read on for our full review of the Audi A4 saloon.

The Audi A4 is a premium car that demands few compromises from its owners. Now in its fifth iteration, the latest one is very much an evolution of the previous model's approach, which has seen the A4 locked in a fierce battle for control over company car parks and suburban driveways for 30 years.

This competition with its closest rivals - the BMW 3 Series and Mercedes C-Class - has turned all three cars into incredible all-rounders, with stunning interiors, low running costs, and impressive on-board technology.

Traditionally, the 3 Series was the driver's choice, the A4 had the nicest interiors and the all-weather security of four-wheel drive, while the Mercedes struck a nice middle ground. Now however, the differences are more subtle, with exterior design and brand image playing a bigger role.

The strangle hold these three models have on the premium company car market has made it very hard indeed for solid left field alternatives such as the Volvo S60 and Jaguar XE to get a look in, despite each having their own likeable qualities.

First launched in 2015, the current model was given a major facelift in 2019. The makeover included fresh styling that cribbed notes from the larger A6 and A8 saloons, and a paired back engine range.

Both the 3.0-litre V6 diesel models and entry-level 1.4-litre petrol were dropped, leaving buyers with a choice of four-cylinder 2.0-litre petrol and diesels, each available in two states of tune. All of the engines are smooth, flexible performers with competitive running costs, and the more powerful diesel model comes with four-wheel drive.

The interior remains a real highlight, with a modern and minimalist design that features high quality materials throughout, seamlessly integrating the impressive array of new on-board technology.

Buyers can choose from three trim levels: Sport, S line, and Black Edition. Even the standard Sport comes amply equipped, with a spec-bump compared to the old SE that includes sat-nav, heated seats, a 10.1-inch touchscreen, and a 12.3-inch set of digital dials that Audi calls its 'Virtual Cockpit'.

Add to this long list a set of front and rear parking sensors, cruise control, and satellite navigation, and it seems hard to understand why anyone would need to upgrade to the pricier models, apart from their increasingly sporty exterior styling kits.

For a four-door saloon, the A4 is pretty practical too, with a decent boot, folding rear seats that split 40/20/40 and room for four adults to travel many miles in relative comfort. However, family buyers and those who need to regularly carry more should opt for the A4 Avant estate, a roomier version that we've reviewed separately.

The A4 excels on the motorway, where its hushed engines, supple ride (as long as you avoid the stiff sport suspension) and excellent cabin refinement make it a relaxing companion on longer trips. It handles winding roads with strong grip and reassuring poise, but several rear-driven rivals are a bit more fun in this regard.

Its premium pricing (it's expensive compared to the mechanically similar Skoda Superb and Volkswagen Passat) is offset by decent residual values and low running costs, with the cleanest 2.0-litre diesel models capable of achieving well over 50mpg in real-world conditions.

Has Audi changed the timing belt renewal interval?

"Has Audi changed the timing belt renewal period for 2018 A4 1.4 TFSI?"
The timing belt interval for certain Volkswagen Group engines has been increased to 125,000 miles, but according to many readers this has not been communicated directly to customers and has only been explained to them when in communication with dealers directly. There is no harm in having a timing belt changed ahead of the recommended interval - in fact if you plan to keep your car longer term, we would recommend changing it at five years or 60,000 miles for complete peace of mind.

Are both the Audi A4 TFSI 35 and TFSI 40 virtually the same?

"Are Audi A4 TFSI 35 and A4 TFSI 40 running cost the same (mpg, tax, emissions, insurance ) ? Apart from HP 150 and 200, all data i see varies. Some suggest 35 is cheaper to run, others suggest there is no difference, in which case what is the point of splitting the same engine? "
The Audi A4 35 TFSI and 40 TFSI use the same 2.0-litre turbocharged four cylinder engine, just with a different state of tune to provide 150 PS in the 35 TFSI and 204 PS in the 40 TFSI, as well as additional torque. As far as the official figures are concerned the 40 TFSI is slightly better with a claimed fuel consumption of 45.6mpg compared to 43.5mpg in the 35 TFSI, as well as fractionally lower CO2 emissions. In the real world this may not translate to a significant difference in terms of economy, the VED rate will be the same (assuming both are under the £40,000 premium) but you may find insurance costs are slightly higher for the more powerful 40 TFSI version. The reason Audi use the same engine in two different guises is that it is cheaper to build many examples of the same engine with few or no mechanical differences while offering the customer a choice of power outputs and charging a different sticker price.

Can I claim for an oil leak on a car I bought in 2017?

"Back in 2017 I bought an Audi A4 1.4 Sport TFSI for £13.5k which had 48k on the clock. The dealer gave me a three year warranty and a fresh MoT (No advisories) A few weeks later, a tyre pressure sensor fault code popped up, I had also started noticing drips of oil on my driveway. I took the car in and told the service department about both these issues. They told me that the mechanic forgot to reset the tyre pressure sensor but they couldn't find any leaks. Now there is pretty big leak with a very noticeable stain on my driveaway and the rear underside tray under the spare wheel is completely soaked/stained. I took the car back in and they're saying that it will cost me out of my own pocket for this oil leak as It's not a mechanical/electrical failure, they're telling me that only mechanical/electrical failures are covered under warranty. Is there anything I can do to fight this?"
Although the car was sold with a clean MoT, this is not a guarantee that there are no problems with the car and is only a snapshot of the condition of the vehicle of the day of the test. If you bought the car in 2017 with a three year warranty this would suggest that the warranty has expired, so unless you took out an extended warranty this is unfortunately something you will have to pay for from your own pocket. However, if you do have an extended warranty we would argue that until the cause of the leak is determined they cannot say for certain that it is not a mechanical fault, which would be covered under warranty.

What is the running-in period for an Audi 2.0-litre petrol engine?

"How many miles does it take to run in an Audi 2.0-litre petrol engine?"
Assuming your Audi is brand new, the recommended running-in period is 1500km (approximately 1000 miles). During this period you should avoid using full throttle or maximum engine revs, as well as avoid labouring the engine at low engine speeds, particularly when cold. You should also avoid towing during this period. Even after this period is past, waiting until the engine is fully warm before using all the available performance will help its longevity.
