There can be faults and problems with any make and model of car,if you have a read through the A4 B6 threads you will get the idea of the main types of problems reported but this does not apply to all, some can be classed as lemons i suppose and also problems can arise from driving styles/lack of maintenance etc.. As long as the one your thinking of buying has a full service record it should be fine with only 40 k on the clock
