My E350 started to miss a little on medium revs (around 40mph) but no warning lights. I sent it to MB dealer and they diagnosed blocked EGR valve, which they replaced. Since then the same fault occurs randomly and my fuel consumption has increased even with careful driving. Today I accelerated hard up a steep incline, kickdown was OK but there was very little power, as speed increased slowly after maybe a minute or so power built quite rapidly but nothing like it should. Could this be turbo related?
Still no warning lights showing.
