Dual-zone electronic climate control is standard, with independent settings for driver and passenger plus dust and pollen filter. Cruise control is optional. Acoustic parking sensors are optional for rear or front and rear. Higher trims add a colour driver's information system and optional CD or DVD satellite navigation with colour display. No factory reversing camera is offered. The cabin has a leather multi-function steering wheel, height-adjustable seats, and through-load ski bag facility as standard on many versions.
Boot space measures 246 litres with the soft top down and expands to 315 litres with the top up. The soft-top box is variable to free up more luggage room when the roof is raised. A through-load facility is available for longer items.
Braked towing capacity reaches 1600 kg on most versions, with unbraked limited to 750 kg. Payload is typically 405 kg. Sport and S line trims offer firmer sports suspension as standard or optional.
The cabin feels solid and well finished with dual-zone electronic climate control standard, a leather multifunction steering wheel, height-adjustable front seats and aluminium inlays. Optional electric multi-way seats with lumbar and heated front or rear seats add convenience. An optional acoustic soft top cuts road noise almost to saloon levels with the roof up for year-round use. Rear seats suit two with decent shoulder room but limited legroom.
Fuel tank holds 70 litres.
Service intervals follow fixed regime every 15 000 km or 12 months, or LongLife flexible up to 30 000 km or 24 months.
Standard safety includes ABS, ESP, dual front airbags, front side airbags, automatic rollover protection, seatbelt pretensioners and ISOFIX.
Galvanised body with 12-year anti-corrosion warranty.
Engines range from petrol 1.8 T and 2.0 TFSI to diesels like 2.0 TDI and 3.0 TDI, with combined consumption figures published per variant such as 8.5 l/100 km for the 1.8 T. Fuel choice is Super unleaded for petrol or diesel as marked, with a 70-litre tank common across most models.
Servicing uses either a fixed schedule with oil changes every 15 000 km or annually, or the LongLife system that monitors oil condition for intervals up to 30 000 km or two years. Brake fluid changes every two years and soft-top plus rollover checks are advised at the same time.
Safety kit is comprehensive for the class with dual-stage front airbags, side airbags, ESP with brake assist, pretensioners and an automatic rollover system that deploys bars behind the rear seats. ISOFIX points are prepared front and rear. No dedicated Euro NCAP rating is listed specifically for the Cabriolet body, though the related A4 range scored well in period tests.
The body is fully galvanised for long-term corrosion resistance under a 12-year warranty. Soft-top care involves regular checks of the electro-hydraulic mechanism and fabric condition to keep it sealing and quiet. Overall ownership centres on following the service indicator and watching common wear items like belts on certain engines.
