Re: Colour me surprised
I too had a 2008 Toyota with a D4D with the DPF fitted (a T-180 Avensis). And yes, MPG would peak at 38MPG, usually averaging about 33MPG. Much worse than the older Avensis with same engine, but without the DPF. Unimpressed.
In hindsight I think the problem was a gradual build up of soot in the EGR valve/Exhaust manifold - strip it and clean this and people claim that MPG > 40MPG can be achieved. Should have been a service item?
So were Toyota being incompetent, and/or unethical towards their customers?
VW engineers clearly were competent but highly unethical with their cheat devices.
