Hello, yesterday the warning light which is referred to in the manual as “warning lamp exhaust gas cleaning system” went to my V60 D4 MY13. The manual recommends to use the service of a contract workshop. I then went to the. The workshop master said that he could not do so much, which did not satisfy me. After a little drilling he let himself be persuaded to hang the car to Vida. He might say it will be a quick shot. After about 15 minutes he came again and said he could not find anything in the short time. I should come back again if he had more time. My question if I could drive the mindlessly was answered by him with yes. Then I did not have it based on it. Is it indeed so difficult/long-term about the OBD interface to read out the errors of the steru equipment? Or is there possibly so many error messages that the master needs to read about these hours? Or is there perhaps even no error message at all? There was no message in the display at all and start/stop is still going on. Also the car drives in the end? Does I have some kind of warning?
