E 220 1994 white smoke
I have E220 that is in good condition.
I was visiting a friend and everything was ok. Then when I'm leaving I tried to switch it on a pop sound and it turned off. Tried again and it worked. When I drove home it was a very short distance and I noticed a white cloud coming up from the exhaust. I tried to smell it but I noticed nothing. I turned it off for half an hour and came back to check for Engine oil and it was OK. On the proper level
Coolant and it was OK on the proper level and I opened the engine oil cap to check for any mixing but I noticed nothing
I need a solution for this crazy problem and I need to know what could be the problem ..
Thanks
