Unknown white smoke from exhaust.

This is a strange one.
Drove my PETROL C class for about half an hour yesterday no problems, through normal roads. Pulled onto a motorway and accelerated to join traffic... Massive amount of white smoke started pouring from the exhaust. It was like someone had set a fire in the tail pipe.
I pulled onto the hard shoulder, switched the car off for about five minutes. Switched it back on and drove home, another journey of non- motorway driving for about half an hour. I accelerated hard a couple of times, no smoke and was fine all the way home. No error lights on the dashboard and normal temperature / engine performance.
I took it to my local garage this morning, no error lights, no fault codes, everything checked out fine.
Has anyone seen this before? Someone mentioned something about a "re-gen" but I thought this was only diesels. Any information / ideas gratefully received!

Hi,

Monitor your coolant levels in the primary and intercooler systems. See if you notice any bubbling when idle or on revs and if you can notice any drop in levels.
