I have a mk2 ford focus tdci 2.0
Monday night my car died, but started first time with a jump but spewed out lots of white smoke which cleared after about 5 mins idling and 500m driving. I did not notice any unusual noises during this drive.
Anyway put a new battery on from ford (farther in law works for quicko) started up first time no smoke no lights on dash. Took it for a drive and there is a whistling noise when I accelerate which was not there before I changed the battery. There was no performance issues, or smoke when I drive it now.
I am working for the next 4 days so cannot get chance to have a good look in day light as I work 12 hour days.
Is there anything I should be looking for in particular before I take it to a mechanic?
Oh just to mention serviced last March by a friend all filters and oil changed including fuel filter and blanked EGR
