mike.gamble Posted January 31, 2018 Report Share Posted January 31, 2018 I’ve just removed and cleaned the egr valve on my 1.0 Lupo and refitted it as I had a warning light on the dash. however, since re-fitting I’ve noticed my exhaust is steaming when being driven. It’s not a case of it’s cold and needs to warm up, it’s there after a few miles and it never happened before. It starts and runs fine and I can’t work out what’s causing it. I’ve refilled the header tank and it doesn’t seem to be loosing any coolant. Any ideas? Quote Link to comment Share on other sites More sharing options...
mk2 Posted January 31, 2018 Report Share Posted January 31, 2018 Hydrocarbon + oxygen = water + co2 in cold damp weather, it's normal. Usually a sign that your engine is running well. Quote Link to comment Share on other sites More sharing options...
mike.gamble Posted January 31, 2018 Author Report Share Posted January 31, 2018 Really? shouldn't that stop after a few miles when the engine is fully warm? Quote Link to comment Share on other sites More sharing options...

mk2 Posted January 31, 2018 Report Share Posted January 31, 2018 In canada when the outside temps are like -40c, the exhaust gas goes straight to snow! Ok, so really small snowflakes, but it basically comes out like white dust! Quote Link to comment Share on other sites More sharing options...
