An awareness of a growing importance of quality and reliability of products against competitive international markets tends to improve the quality of all of the processes that make up their activities and to generate products of an increasing quality and reliability [1]. This analysis of quality and reliability is systematic and independent of the action in the field of quality assurance and reliability of products carried out in order to check whether these activities and their results are consistent with planned ones and if they are effectively used to achieve the objectives [2]. The aim is to carry out an analysis of Audi engines malfunctions, to be specific A6 model, types C6 and C7. The essence is based on verification that the new generation 2011 model has boosted the reliability of assembled engines. This topic is of particular importance, because it raises the aspect of actual quality and durability of new engines during their three years of operation. The available literature has no signs of related examination. The analysis of the reliability consists of four major stages: 1) structural and functional analysis of objects 2) qualitative analysis of the problem, the aim of which is to identify all possible factors affecting the reliability of the object 3) quantitative analysis of issues, leading to the estimate of measurement reliability, 4) draw conclusions [7]. The study 20 used Audi A6 cars was to compare randomly selected 10 vehicles C6 generation coming out in 2004, and another 10 vehicles C7 generation presented in 2011. In order to carry out a separate analysis of malfunctions of engines, in each type the cars were chosen in such a way, that the 5 of them were equipped with spark-ignition engine and another 5 with compression-ignition engine. The data of these faults was read from service programs such as Autostacja and ElsaPro on the basis of submissions in an authorized Audi service in Wroclaw.
