Very lucky to have a very well spec Audi, the Sat Nav is excellent, though will need to buy new updated disc.
Finding the factory fitted solar sunroof works really well, now the UK weather is starting to warm up. Initially thought that this was just a gimmick. Have found that if you have anything dangling from centre mirror, the alarm goes off when stationery, due to the air being circulated around car. Rear window blinds also help to keep car cool.
Engine with Multi-tronic gear box very smooth, with plenty of punch when used in sport mode, or manual option. Had to have gear box oil changed at 40k, costs around £175 and now even smoother gear changes. Average around 40mpg on long trips with average speeds around 75/85mph. Just maybe could to with another 20/30 bhp to help pull heavy engine.
Handling is generally fine, with car riding on 235x40x18 wheels/tyres. Very relaxing on long motorway journey's. Cornering is good and should improve when replacing cheap existing tyres with x4 Michelin Sports shortly.
Leather seats very supportive and love the full electric operating options. Very easy to get comfortable driving position back after my wife has used the car.
Service intervals have got me slightly miffed. Previous A4 tdi's have managed to get 20,000 min between service intervals on long term service. When I purchased this car from an Audi dealer, they claimed that car had just been serviced by them and computer would calculate next service once car had settled down. Most of my driving is long motorway miles and looks like will only get around 14k before needing long term service, when other reviews claim 20,000 plus.
The cabin is very bell built, as per normal Audi high standards. Doors all clunk shut with an air of quality and interior has plenty of life left.
