Diesel DPF recall
I've just received a recall letter, describing that with DPFs, under some driving conditions 'engine oil levels may rise'. The recall is to check the oil level + a software update. According to my letter, it affects S60/V70/XC70 & XC90, 2006 to 2009.
When they say 'oil level may rise', I assume they actually mean 'fuel may enter the sump', which I think I've read about elsewhere with DPFs.
Anybody know what it's all about? Is it some bodge to try and paper over the cracks in DPF technology, or is it a worthwhile improvement?
