Hello dear Volvofans, now comes: Volvo V50 2006 Year of manufacture Engine: Diesel D5 Gearbox: Automatic Km: 25000 already has the third engine after two engine damage due to oil dilution! 1. Engine damage and change was at approx. 23000km (only engine change) 2. Engine damage and change at 25000km (motor change + injectors + turbocharger) Has anyone ever heard of this? OIL RENEWAL ! I suspect the oil dilution comes from the automatic regeneration of the particulate filter and the The vehicle always seems to try to regenerate the particulate filter. Volvo is currently testing and testing! It is not an isolated case … check your oil level before changing the oil! The oil is very thin and smells like diesel. To the engine damage it is actually only at full load on the highway. Volvo has no explanation yet…do you have a? are you aware of other cases? Thank you and greetings Grisu86
