    TBH I haven't noticed, but I'm going to look tomorrow. I guess the engine is under more load with the air con on so it needs to burn more diesel and creates more smoke.

    maybe so........if you stand outside and rev it you'll notice,and also leave it on idle and you should see smoke if you look carefully,or if you boot it alot more than usuall

    I guess those with a DPF will smoke less too, just to confuse matters.
