Im having trouble with my parents car at the mo and im having trouble getting to the bottom of it
noticed that coolant had gone from the header tank after plooms of white smoke came from the exhaust, the car was running fine but smoking like dot cotton. After a bit of diagnosis the egr cooler was at fault replaced it and got it running. it was still smoking but no coolant was being lost, took it for a drive and it felt down on power and still smoking
I started it up this morning and no smoke took it out and when it got up to temp would smoke again more so on idle?
I must add the temperature has not risen above normal once
