Polo Auto Air not thorough and they make costly mistakes

<p>I took my car to them several times initially for a service and then to get the parts they recommended replaced and spent quite a lot of money with them. On more than 1 occasion they worked on my car before getting approval or even letting me know how much it cost. On the last occasion they forgot to put my air filter back in my car (its huge you cant miss it).</p> <p><br />Still, after everything they replaced did not fix my fuel consumption issue. On taking it to a private mechanic, he deduced that they had used the wrong reference points on my cam-belt replacement resulting in a timing issue which was causing a higher fuel consumption and shuddering when idling. So I had to pay someone else to fix something they should've done to start with.</p> <p><br />Although seemingly friendly, they are not thorough and do not give you confidence their work.</p>
