We hope you found the inaugural Inside Line on the Ford Focus as useful as we did. We’ve been swamped with technical information from every corner of the market, all of which you can see here, but more is always welcome.

This month we turn our attention to the popular Audi A4. In particular, we’re looking at the model which began production in 2008 and is still being used today (although the car did receive a facelift last year). Available in saloon, estate,  and Allroad Quattro body styles, the A4 came with seven different engine options split into three diesel and four petrol units.

The most popular model is the 1.9 TDi SE, of which there were 11,000 on UK roads last year. Also popular is the 1.8 petrol unit in SE trim, where 9900 were on the roads in 2012 according to the website

Rest assured you’ll find all the information needed to fix these problems here and online.

Next month we’ll be looking at the Peugeot 308 (2007-). To get your advice included contact or
