We have a 57 plate V50 D5 and have today received a letter from volvo in a recall envelope, notifing us of a possible fault with D5 engines, with particulate filters. It saies they have had reports of engine oil levels risingabove the max due to overfilling / dilution by fuel. In certain situations this causes engine speeds to be maintained or increased after the throttle pedal is released or car to continue to run after it as been switched off. By coincidence I checked our engine oil level last wednesday and thought the level was high, and oil seemed runny, and engine was cold. The car has only done about 1500 miles since service in jan / feb this year and i havent checked it since that service so dont know if they over filled it or if it is this problem. If it is this problem, surley it has not done the engine much good running with fuel diluted in the oil. Anyone had the same notification, or suspect they have the same problem. Any thought on the damage that may have been done with diluted engine oil. http://www.volvoforums.org.uk/showthread.php?p=680316
附加:國外對XC70空污報告 (有可能是D3/D4取代D5原因) Air Quality Random Testing of VOLVO XC70 Results in Recall and Improvements The EPA's random testing of new automobiles has shown that some importers of the VOLVO XC70 D5 AWD has NOX emissions as high as 0.28 g/km. This exceeds the limit of 0.25 g/km stated in Article 5 of the Transport Vehicle Air Pollutant Emission Standards (交通工具空氣污染物排放標準). After confirming the substandard results of random testing, the EPA annulled the exhaust certification for this make of vehicle according to regulations and has required businesses to cooperate in recalling all vehicles and making the necessary improvements. In order to maintain domestic air quality the EPA has set the Vehicular Air Pollutant Emission Standards (交通工具空氣污染物排放標準). Vehicle exhaust must conform with given standards before they can apply with the EPA for exhaust inspection certification and obtain a license from motor vehicle supervision offices. The EPA also conducts random inspections of new car models to ensure vehicles sold by businesses comply with standards. If new car models fail to pass random testing, the EPA will cancel the existing exhaust certification for that model and require businesses to recall all cars and carry out improvements to prevent those cars from negatively affecting air quality. The 2009 model of the VOLVO XC70 diesel sedan has received exhaust certification by the EU. As Taiwan follows EU emission standards, the cars were eligible for exhaust testing certification from the EPA. From 24 October 2007 to 15 August 2008, a total of 154 VOLVO XC70s were imported. During random testing of new vehicle models, the EPA found NOX emissions of this model in excess of emission standards. The importer has promised to recall all cars of this model and confirm the reason for substandard test results with the VOLVO factory in Sweden. After determining an effective response measure, the importer will inform all owners of this car and ensure the necessary improvements are carried out.
