I had my Focus TDCi in for a service today. When I collected it, it was
running roughly and billowing white smoke out the exhaust. This cleared
after they revved it for a while and appears to be normal now, with a clear
exhaust. The rough running was due to air in the fuel system resulting from
the fuel filter change, but I am a little concerned about the white smoke!
Does anyone reckon I have any cause for concern, or is smoke normal with air
in the system?
Thanks for any advice.
