A4 S line buying guide

[YoYo_Man]

Hi guys,

I'm looking to buy an A4 S Line (2008-2009) model. Hopefully a 2.0 TFSI or TDI. Budget is about £7500. I've never owned an Audi before, my car history includes: Peugeot 306, Ford Focus, BMW 3 series and currently got a Honda Civic.

• What are main things to look out for?
• What mainly goes wrong on these cars?
• Do these have a chain or cambelt? If belt, when is recommended change?
• How reliable is an Audi automatic gearbox?
• Anything else I should look for...

Thanks in advance
