Our touran has had intermittent cold start problem. New battery, glow plugs in last month. Sometimes it starts first time from cold, other times it doesn't want to go. It is getting power to the glow plugs. Wife swears she is keeping the glow plugs on most of the time. On occasion she did forget, then when she turns key on and off, puts glow plugs on it just will not start. Eventually will if cranked over enough.
any advice would be much appreciated. Paul
