So, if Audi's right and A4 allroad customers aren't buying this car to go off road, just why are they buying it? Image perhaps? The plastic cladding, redesigned grille and under-bumper section, side sills and tough-looking wheel arch extensions certainly lend it a purposeful air that's continued inside where shiny sill plates, special upholstery and various unique dashboard applications give it a slightly more rugged ambience. You'll certainly feel rugged if you drive it on a muddy farm track, then get out, since the lower parts of the doors collect mud from the 17-inch tyres, swiping on your legs with every entry and exit.
Basically of course, this car shares the standard A4 Avant cabin design, which means decent amounts of space, classy design and levels of build quality that rival marques are still doing their utmost to match. Providing you're only transporting four adults, there's plenty of head and legroom at the front and at the back. Luggage-wise, the well-shaped 490-litre boot is a decent size and features a useful reversible floor, one side offering a wipe-clean surface for muddy boots and dogs. The rear seats fold down to increase luggage space to 1430-litres but it's a pity that they don't fold completely flat.
It's highly unlikely that any A4 allroad model will have been used off road to any great extent but it's worth checking the sills and the areas around the axle just in case the previous user got unwisely carried away at some point. Otherwise, the issues to look out for are just the same as those that apply to any other fourth generation A4 model from this era.
Reliability isn't generally an issue for this model line. Many models will have done high mileages in the hands of overworked sales reps but that shouldn't necessarily put you off. Look for a fully stamped-up service history and keep an eye out for uneven tyre wear on the more powerful models.
The most common problem with A4s occurs in some area of the electrical components; e.g., the brake lights stay on, the trip display burns out in a few spots, or the power window motor might burn out. These repairs are not very expensive, although having to replace a bad circuit for the taillights would be pricey. We'd steer clear of an A4 with trip display problems too, because replacing that screen is expensive.
In the highly unlikely event that some sort of engine problem presents itself, it would be expensive to repair because of the quality of the parts. On an older very high mileage car, you should have the timing belt replaced if it hasn't been already; should it not be replaced and it breaks, you expect a hefty bill and the engine compartment would be in bad shape if this were to happen. Have the brakes checked as well; the car in question might need new pads/rotors.
(approx based on a 2012 A4 allroad 2.0 TFSI) A clutch assembly kit will be around £250 and an exhaust system (without catalyst) will be about £300. An alternator should be close to £150 and a radiator around £170. Front brake pads are around £75, rear brake pads will be £50.
It'll be good news for potential owners that the modest changes made to give this car some modicum of off road ability not only failed to disrupt its admirable on-road composure but actually in many ways improved it. The A4 allroad's springs were lengthened for extra off road ground clearance, with an added 26mm of travel upfront and 13mm at the rear. The by-product of this is a huge improvement in ride quality over a standard A4 Avant. Firm damping and a 20mm wider track that compensates for the increased ride height mean that bodyroll is well contained too. New model buyers who were planning to throw the car round a bit on tarmac had the option of specifying Audi's 'drive select' vehicle dynamics system, a multi-function software system able to control everything from the suspension to the gearbox and from the steering to the throttle mapping, via 'Comfort', 'Auto' and 'Dynamic' settings.
Audi reckons that very few of this car's customers ever take it off road but those that do find themselves at the foot of a steep rutted track may well find themselves wishing that the Ingolstadt engineers had fitted the larger A6 allroad's model's reassuringly clever height-adjustable air suspension, at least as an option. Still, with 180mm of ride height - 37mm more than a standard A4 Avant and just 20mm shy of Audi's fully-fledged Q5 SUV - improving both approach and departure angles and stainless steel under-body protection, you quickly find that this car has enough capability to deal with anything but situations you shouldn't have been in in the first place.
It helps here that the ESP stability control system has been re-engineered for off road conditions, incorporating an ORD Offroad Detection system that monitors the level of grip available at each wheel and allows an extra degree of wheel slippage in muddy or low traction situations to help the car maintain forward momentum. In these conditions, the ABS won't cut in quite so easily, allowing the wheels to lock up earlier, so building up a dirt buffer in front of the tyres that will stop you quicker.
The engine range is loaded with familiar Audi units. A 141bhp 2.0-litre TDI option was offered but the majority of buyers chose the 168bhp 2.0-litre TDI diesel, which has a 6-speed manual gearbox. The other diesel alternative was a larger 237bhp 3.0 TDI variant that boosts torque from 350 to 500Nm. Pulling power of this kind is just as well, given that any allroad model must carry around 35kg more than a standard A4 Avant quattro. Like the 208bhp 2.0-litre TFSI petrol variant (this the sole petrol option), the 3.0 TDI engine comes with Audi's clever S Tronic twin-clutch 7-speed semi-automatic gearbox which, if you're quick with the steering wheel paddles, will get this particular A4 allroad through the 60mph barrier in a brisk 6.4s, half a second quicker than the petrol variant.
If you're after a true multi-purpose vehicle, want an executive feel but don't need massive amounts of space, the temptation is to look at the various SUV options. This 2009 to 2015-era Audi A4 allroad model though, could actually prove a more agreeable everyday companion for many drivers. Residing somewhere between a compact executive estate and a compact SUV, it aims to balance road-going competence with light off-road ability. Factor in the big boot and Audi's quality interiors and you have what should be a convincing product. And an eminently sensible one.
