I have had the following problems with my S80 D5 (12/2002, 84.000km) for a few days: When the engine starts cold, the engine starts badly and goes off immediately after starting. It runs without any problems at the 2nd start. Then, when you drive in the sliding mode and then there is gas, it always jerks short and somehow some power seems to be missing — V-Max is still reached, but the acceleration is somehow not the same as before. Furthermore, the turbo sounds funny. it uses (approx. 1,750 u/min) you can hear in the interior (even when the radio is switched on – at normal volume) a kind of grinding or scraping noise which lasts up to approx. 2,200 u/min, after that it is gone. What do you think, especially because of the turbocharger noise? With the injectors I have already found a lot about the search, but I am certainly not. I could not find anything about the turbo. I already called my workshop today and he also said that e vtl. what of the exhaust gas recirculation could not be correct?!
