I thought I would document my experiences with this issue here for others to see. My 2011 Rav4 Dcat Automatic has a little problem, once it is warm after driving a couple of miles, when I accelerate from standstill in slow moving traffic I get quite a large cloud of white/grey smoke behind me. The sort of cloud that makes people stay further back as it smells like a dirty diesel. The vehicle has 60,000 miles almost bang on. The oil and filter is clean as I changed it last weekend.
