When going to Copenhagen airport, the motorway ends at a roundoubout.
So you drive at a speed of 110 km/h (70 mph), take the foot off the
accellerator to slow down and finally stop at the roundabout, waiting
to get into it.
A year ago on a foggy/rainy day at a temperature at 5 C (40 F), I
drove that way in the morning rush hour, and when stopping at the
roundabout, the engine went out and couldn't be started.
Well, that wasn't funny, because there is only one lane into the
roundabout, and I blocked that. Imagine the concert of horns behind me
(and I was already in the last minute to catch the plane).
After some 10-15 minutes, it could be started, and the engine ran
smoothly again. No problems since.
Until today. Exactly the same weather conditions and exactly the same
roundabout. Fortunately, there was no cars in the roundabout, so I
could roll aside. And I was not in a hurry this time. So I tried to
start a couple of times while listening to some good music, and after
10 minutes I started and drove away.
An hour later on my way back, exactly the same happened at the exit of
My theory is, that the sudden high vacuum in the intake causes some ice
build up due to the very humid air and the relatively long time it
takes to slow down, and the 10-15 minutes is the time needed to melt
Has anyone else experienced this, and if so what to do about it ?
