We have a 65 HSE luxury. In September my wife was driving the car and white smoke started coming into the car. So thick she had to pull over. Pressed the button and got a mechanic out. No fault found. Went to local dealers again nothing found. This week I was driving and the same thing happened I noticed that stop start although on was not working the car filled with white electrical smoke and I had to pull over. Looked under bonnet and cannot see any source. Very worrying and now don't want to drive it. This is our second car so am worried and wonder if any of you have experienced this. I have read posts about adblu and exhaust and don't think it is this. Any help would be appreciated
