Audi RS4 B7: Buying guide and review (2005-2008)

Audi RS4 B7: Buying guide and review (2005-2008) Classic and Performance Car

The Audi RS4 story started in 2000 with the B5 version and it set a template that remains as compelling now as it was over a decade ago: sure-footed quattro drivetrain, relentless performance, a quietly sinister aesthetic and the sense that 100 years from now, this car will still perform with the same deadly combination of speed, stability and sheer grip. 
The second-generation car, the one we’re looking at here, could scarcely have been more different in many respects. Out went the estate-only configuration, the heavily turbocharged engine and a bit of the sense that the RS4 was just a skunkworks project. However, those changes were resoundingly offset by the star feature of the B7 RS4 when it was launched in 2006: a normally aspirated 4.2-litre V8 that revved to 8250rpm and produced 414bhp. 
It was as if some rogue BMW M engineers had seen into the future and decided to get out before the turbos arrived, infiltrating quattro GmbH and living out their wildest engineering dreams. One or two might have even made it into the chassis department, because Audi’s usual 50:50 torque split was tweaked so that 60 per cent of drive went to the rear wheels. 
Saloon or Avant, this RS4 was something special, with a sensational six-speed manual gearbox and a chassis that coupled Audi’s usual stability-first DNA with some real fluency, adjustability and entertainment. It cemented the RS4’s legendary status, showed us that Audi had the ability and desire to take on BMW head-to-head in dynamic terms and plain just made us happy. 

Which Audi RS4 to buy? 

The B7-gen RS4 first appeared in summer 2005, though UK sales didn’t get into full swing until early 2006. It was available as a saloon and estate (Avant) and also as a rather unhappy cabriolet (best avoided). It bowed out barely two years later when the B8 version of the A4 appeared. Given such a short production run, it’s surprising just how many you can find in the classifieds, but that’s enduring proof of the way it gripped the petrolhead imagination. The B7 RS4 was simply the best drivers’ Audi since the Ur-Quattro. 
Beneath the flared arches and aluminium front wings and bonnet, the spec remained essentially unchanged throughout the run: 414bhp 4.2-litre all-aluminium V8 (basically the same unit that would propel the mid-engined R8 that followed soon after), six-speed manual gearbox only, rear-biased four-wheel drive, those DRC reactive dampers to provide added tautness in corners, and a Sport button to sharpen throttle response and open bypass valves in the exhaust. There was an optional Sport pack, which made the car sit a little lower and ride a little more firmly and which added ‘active’ side bolsters to the front seats.

Common problems

• A lot of cars suffer a build-up of carbon around the inlet valves. Not every car is affected, but it’s a common problem after around 60,000 miles. 
• You get oil from the breather system in the inlet tract. Direct injection means there’s nothing to wash it off the back of the valves. It’s basically a good day’s work to decoke the heads. 
• Telltale signs include an engine light on the dash and embers coming out of the exhaust (noticeable from a following car at night). Avoiding lots of short journeys will delay the inevitable build-up. 
• The V8 is otherwise reliable, but some ancillaries can need attention. The two side water radiators are vulnerable to corrosion. Look through the ducts in the bumper for seeping pink antifreeze. If you can get the car on a ramp, also check the oil cooler and pipes for corrosion and seepage. Replacement means taking the front of the car off, and parts alone are over a £1000. 
• Service intervals were officially every 19,000 miles, but a good specialist will recommend 10,000 miles or annually. 
• Drivetrains are robust but beware a heavy clutch – replacing it takes around eight hours. 
• The Dynamic Ride Control dampers are prone to leaking. You can keep replacing them, but many owners go for Bilstein coilovers, which retain the standard ride height. 
• Bushes and ball joints in the suspension last pretty well but may need replacing around 80,000 miles, depending on the life they’ve had, so listen out for knocks and bangs from front and back 
• Bouncy suspension means the DRC’s gone. There is a drivetrain clonk, but that’s just Audi AWD. 
• The brakes are massive – 365mm vented and drilled discs at the front with eight-piston, four-pad calipers. A full set of discs and pads is around £1500 just for the parts, so if they’ve been recently replaced, that’s a big tick. Vibrations through the pedal mean a bill’s looming. 
• The driver’s seat outer bolster may show signs of wear, while the swollen arches are prone to stone-chipping.

Summary and prices 

The B7 RS4 still enjoys a strong following and prices have levelled out, meaning there’s plenty of support while depreciation is no longer an issue. Running costs can be, though, so be aware of the potential for hefty bills and take care to find a car that’s been well maintained. 
Scan the classifieds and you’ll find a vast range of prices. At the bottom end there are high-mileage cars with multiple owners – usually private sales – for as little as £15,000. Don’t necessarily be put off by a high mileage, but an inspection by a specialist is likely to be money well spent. At the very top end, pristine, low-mileage, one-owner cars are advertised for as much £35,000. But around £20,000 gives you a fantastic choice of average-mileage cars with only one or two owners and excellent service histories, and that’s where we’d be looking. It’s worth noting that you’ll pay £250 less road tax a year on cars registered before March 23, 2006.
