when we say it disappears when its warm i would suggest that is in excess of 50 miles, I had this and to expel 2 litre of condensation in all 3 boxes on your exhaust takes more than 5 mile trip, As has already been suggested it common and normal far more than other cars to have grey vapor from exhaust over the entire winter its normal and just what the car does,........................... over 50 miles on occasion when you do that journey i believe the exhaust will be clean and nothing will come out exhaust once its been on a truly long journey
lots of 2-5-10 mile journeys used 1-2 times a week and you will have these symptoms all the time
If it all seems under control..............your not going fast enough !!
