Hi,

2 days ago while I speeded up to 100km/h and slow down after I realized that huge cloud of steam (or fumes) came out from the back of the car (I bet it was steam since it was rather white and didn't stink).

When I arrived at a car park, I tried to speed on Neutral to see if this cloud will appear again but it didn't, however engine can get max to 3000 rounds/min.

Also there is no 'hard speedup' which should be (I don't know how it's called in english). Like turbine do not catch on.

What it may be?

 

Any codes?

 

Over month ago there were 1 or 2 times "Engine requires repair" -- or something simmilar (it was in flemish language) but it disappeared and never appeared again.
