Hello Elk-Gemeinde, I have complained in other contexts about my Dickelch. Then everything was quiet, except for the following: I would have liked to have heard something from the experts below you, if motor oil from the plastic tube next to the oil tank – I believe it leads to the compressor – drips down on the lower engine cover and of course also the bottom of the tub. Who has gained experience so far? In particular, it is also up to me to the specialists Z of the “90-er”. The story: XC90D5 Executive 185 HP with toos. Options. EZ December 2006. Already for the first maintenance in 2007, I reported the beginning oil pollution. “You have to keep watching it”. Maintenance 2008: It had become worse. Small amounts of oil on the lower engine cover. I wrote a note for my master and enclosed photos. The bells were pulled on the said tube. At the same time I closed an extension warranty over 3 years. maintenance 2009: the same, only again worse. Oil also again on the cover, note, photos and on both sides comments. maintenance 2010: again a little more oil on the cover, drops on the pipe and under the oil pan. note, photos and the comment: “You have to wait for the further development”. That made me angry, but I have another year until the expiry of the warranty extension. On 08.11. I have already, with regard to the next and last inspection in December, mei a new note with the listing of all the proposals and the latest photos sent to my dear master. His reaction, but only to my telf. demand on November 17: He noted on his report: “Dense engine”, so he told me. So what to do? Who can help? I would be pleased. Greetings to all Doeffi
