Hello forum, as from the user @A346 in the thread “Mayday-Mayday, super lead-free instead of diesel fueled?? Well note now a new thread which fits more to the topic. In the old thread I mentioned that I am not satisfied with the running quietness of the V6-TDI at all. Some users had expressed the suspicion that because of the high mileage the engine bearings may have passed. Since my vehicle was recently in the workshop the workshop could get an overview. Conclusion: The bearings are not necessarily in mint condition, but need change they are also not at all. Perhaps the previous owner had already had something done. No idea… I have experimented with an oil additive in the last few weeks and can already record a small success (Xado Test) The additive has developed after about 2000 km the full performance according to the manufacturer and can hardly feel any idleness in the course of an oil change again. This oil change is now and I wonder if I can reach something with a special oil? So the background is still the outside temperature.
