Ford Mondao 2010 TDCI white smoke!??

[Hunter1994]

I have a 2010 Ford Mondao TDCI that has recently started blowing white smoke. The car had a engine malfunction error on the dash for a long time. It has 479,xxxkm and drives great. Problem is just today I had the codes finally reset and that removed the error message but since that message has been removed it is now blowing white smoke at idle. It has never done this before and seems odd that as soon as the codes are cleared it started blowing smoke.
