Right I really hope some one can help me I have a tdi 130 awx engine in my vw t25 van. When I start it from cold it bellows out white smoke maybey with a blue tint. So I have replaced the green cool temperature sensor and the glow plugs and it still happens. I know the engine is good because when I start the engine with the green temp sensor unplugged the engine runs with no smoke at all. Any help would be appreciated please thanks sam
