   Hello,
   
   I read many threads related to this error,but I didn´t find final cause of this error.So please if someone has same problem,how did u fix it.
   
   I changed coolant temp sensor,checked the ground wirings,replaced MAP sensor,fuel filter and I have new battery, after change these,my cars runs about 800 km without any trouble no cold starts issues,but it´s back.I´m starting to be desperated.
   
   When I start my car from cold,idles like shit,it´s resonating and vibrating and sounds like old diesel,but after bout 30 seconds it´s fine.It´s very annying and I need to stop and start it again.
   
   
   Any help much apreciated
   
   Michal

   Maybe your coilpack is on the way out, its a common problem on saxos,also check/replace your spark plugs...
