Question type: Maintenance & Repair

Hi, I just acquired a bmw E90, drove it same day no issues driving but noticed a bit of
smoke come out of bonnet twice. Took it to the machanic, oil changed and coolant water
replaced.Got home parked and in the morning decided to open radiator and found milky
color around it and gushing out while i opened it after it had ran a lilttle.Checked oil all
good as it was serviced same day of purchase and no noticeable oil leak on the floor.
Now I have to drive over 2000km back home. Is it best to drive this car? I don't want
dramas on the way. Pls help

You should never open the expansion tank while warm. BMW coolant will dry a milky white. Why did you open the cap, was it leaking? I suspect the expansion tank would need to be replaced as they develop hairline cracks over time. I wouldn't drive it till you had it replaced. Surprised the mechanic didn't replace it.

No it wasn't, was just curious as whether oil is getting into the coolant, which produces the milky color. Its been repaired now as gasket will be changed, I have to leave tomorrow. Anything else I can do?
