Please i need help. i have ford focus zetec climate tdci 2007. I have had it 3 week n had nothing but trouble. i need a proper mechanic not what computer says... when it starts from cold alot of white smoke comes from exhaust then it judders wen driving. this only lasts 10 min until cars warm then drives fine even if turn off engine then start back up. i have had new egr valve and manifold fitted which cost me £550 :-(...plus all new filters and oil but it still persists. it is not losing power or water..there is NO engine management light on so a diagnostic computer will not show out.. can someone pls shed light on this?? has anyone else experienced this sort of problem?? someone thinks could be glow plugs but the engine ticks over fine its just the white smoke and juddering when driving which disappears when put foot down... thankyou pls pls anyone help
