Hello guys,

I have a problem with my  406 hdi yr 02. In fact when I am on the 4th
gear, i can push upto 130-150 km/h however when I step up to the 5th,
the car either stays still, no increase in speed or if i am on a
sloppy road, the speed goes down drastically. I have had the injectors
changed, the air intake cleaned, the diesel pup and filters changed
but still no change. However I have a yellow indicator light on my
board and have a Antipollution error on the display.

Anyone ahev an idea...?

Thanks in advance ;)
