hi iv got vectra 2.0 dti on 2003 plate and its using alot of diesel i get around 90 miles to £20 and it is smoking alittle on acceleration , has had new head and gaskets due to broken glowplugs and new diesel filter , also had diagnostics but no codes do notknow what else to do
just keep plugging away, my folks have the very same model, borrowed it today very smoky on startup but its at 112k serviced only when its undrivable and it seems indestructible, throw more diesel at it and forget about it. carefree motoring
i know the dti engine is pretty bad for egr going which for some reason is connected to the manifold and when fails you have to replace the whole lot. It could be anything thou until you get the fault codes read.
Diesel leak off pipes go brittle and snap. Each injector has a leak off pipe that it connected by a T piece, these often cause poor running / smoky startup / bad MPG. Replace with some new T pieces and silicone pipe.
thanks for replies had new leakoff pipes and t pieces and was timed up ok , i will give it a service and see how it goes if no better will scrap it as spent to much money on it
Give it air and oil filters, new oil, redex diesel treatment in the fuel and keep driving till it dies. My mates just done the same and still weighed it in for £150 after it died.
