Hi I have a 2006 1.6 hdi picasso.
When driving the engine light comes on and looses power when I let foot off gas the engine light goes off and is OK again. I tried using vpower diesel and the light never comes on or looses power. I replaced egr valve with a second hand one but hasn't helped. It has errors p0490 p0401 p1162. Only runs in vpower with no light and I don't want to waste money on replacing parts that aren't needed. Any ideas please :/
