Hi  
 
I’ve got an R reg, 1997, 1527 CC Peugeot 106 diesel with 80,000 miles.

When it’s started from cold it runs really rough, missing and coughing
out blue smoke.  
This only goes on for about 10 minutes until it’s warming up then it
runs perfect, no smoke or anything.  
 
I have changed the fuel filter, oil+filter and there are also no air
bubbles in the fuel line.  
The power is smooth and fine when warm and it doesn’t rattle or
anything.  
 
The cold starting device, attached via cable to the water hose, works
and returns fully when the car is warm. It also opens fully when cold.

 
Thanks in advance  
 
Andy
