HI folk, need help: My Peugeot 406 HDI (2.2 liters, manual circuit) Year of construction 2003, KM Stand 177.000 has a new incontinence problem: the gearbox seems to lose oil. Anyway, the gearbox in the left area is wet, the car smells like oil (even in the interior !). The Peugeot workshop said that the oil would probably come from a defective Simmerring to the drive axle. Now I have (for logistical reasons, I have a free workshop of indirect proximity) the question Sim The oil that can be seen on the left side of the transmission is clean. So no engine oil. Strangely enough, the plastic/rubber hose below the air filter box is also oily – also here is clean, clear oil. Odorously, I also do not type on engine oil. Someone a tip where the sauce could come from? Or could it be oil residues that are still before the dew. I’ve already told the free workshop that an engine wash would have been helpful…would that have been done? But I have to make sure that the switchgear is tight…..the stench is annoying, and at some point when there is no more oil in it, the gears will dissolve…. Functions are doing well at the moment. Thanks in advance for qualified tips! Greeting Andy
