Hi all. Can anyone help with this one? My scenic 1.9 dci dynamiquehas been having a problem picking up power. When it gets to about 2000 revs it seems to jump into action but when going up hills it seems to lack power. I have taken it to 2 garages now and the renault garage thought it was egr valve. So I paid them to clean ita nd put it back but they said that was fine and do not know what it is. They also checked the turbo pipes and turbo spins freely.Without letting them have it all day and pay a fortune for them to discover the problem does anyone have any ideas? By the way the light that looks like a coil( that heats the bulbs I believe( sorry im a woman!) keeps coming on. Please help.Thanks Lisa.
