I know the weather is cold and damp but my 280 seems to emit steam vapour from the offside pipe for too long.

 

I did a fast motorway run and vapour was still wafting out after 30 miles today - can't say it's done it previously - but then again I've not been looking.

 

Should I be worried do you think?

 

It wasn't doing it when I got home but the exhaust was well hot!

Always pours out of both mine in weather like this, especially with the flaps open. Wouldn’t be worried about it.
