Been using bio (b100 quality fuel) in my w210 320cdi for about 2 months now, I have noted the following, performance is ok and idle can be smoother as normal diesel has higher ignition qualities giving a very very slight vibe at idle probably due to the torque.

But one problem I have noticed is that coming to a stop from a high speed/thrash or temps above 78 degrees c the idle becomes lumpy until 30 seconds after which the car has had time to rectify and establish smooth running.

I am seeking opinions on this theory of mine as I was wandering whether adding a cetane booster might help me acheive perfect idle.
