Hi all I have a smoking prob with my freelander 2 TD 4 is fine when driven solo. But when towing blowes black smoke when changing up and i mean allot of smoke. Have used it to tow for last 2 years with no problem has only been like this for last few months. Also now on these cold mornings it is very lumpy when idling, it is still good on fuel and has no loss of power any ideas many thanks Dave
