Hello, I inspected a Santa fe 2008 diesel(automatic). 70000km on the clock. It is a real beauty. I noticed white smoke coming from the engine dipstick. Is it a big issue? Also it was a bit sluggish in the test drive compared to the other santys i drove. Is it related. Can this smoke problem be corrected? What would be the likely cause? Should I buy the vehicle? Sorry new to forum. And thankyou very much in advance.
