Poor service

I went to Oudtshoorn Renualt and spoke with Rikus and informed him that the warning light came on. I also informed him that a few weeks ago the same thing happened and that it was an air leak. The mechanic who worked on the car said that it can happen again. I wanted to show him where the problem was previously, but he insisted that he needed to do a diagnostic test. He came back and said that the test found inlet air circuit fault. He said that the car engine was too hot at the moment and asked me to come back in an hour. Apparently, he inspected the air circuit and found that the boost pipe between turbo and intercooler has been modified and that the inlet air pipe was not fitted correctly. He said the pipes would need to be replaced. He also said that they do not have a pipe and that I must drive back to Pretoria and take it to Renualt. I informed him again that the previous time the clamp came loose and asked him to go through the clamps to make sure that it is not the same problem again, because I needed to drive back to Pretoria and if the clamp was getting loose, it would get worse. He was not helpful or willing to carry out my request. Unfortunately, this was not the 1st time that I experienced poor service from a Renualt dealer. Previously, the Renault dealer in Pretoria informed me that it is necessary to replace my turbo (cost of more than R45 000.00). Luckily, I took it to a private mechanic and he found that it was a crack in one of the parts, which caused an air leak and it cost me +/-R6000.00 to repair.
