I have a 2009 seat Ibiza 1.6 TDI sport. When running to temp it’s billowing white smoke from under bonnet. I’ve now had 3 different garages take a look, as well as RAC out and no one Knows why. It’s not losing any coolant whatsoever. I’ve recently had the EGR done due to a previous coolant leak, and then head cover gasket done as they thought that was causing the smoke by oil leaking down back of engine. It’s still smoking with no leaks anywhere apparently?!
I’ve also noticed today the exhaust is blowing dark thick smoke on revs and is stinking, but totally different from the bonnet smoke.
