Heidfirst 1,014 Posted January 17, 2013 Share Posted January 17, 2013 that consumption is way too low.any signs of coolant use?I would be tempted to bung a can of BG244 in & see if that helps at all. Quote Link to post Share on other sites

Sooty 34 Posted January 17, 2013 Share Posted January 17, 2013 It sounds to me as if you may have injector seals leaking.The dark grey is symtoms of excess fuel into the cylinders.Does it only do this on cold start and on very cold days? Quote Link to post Share on other sites
igormus 19 Posted January 17, 2013 Share Posted January 17, 2013 grey smoke is the sign of ofer fueling and restriction of an air from turbothe possible reasons are:- air filter- air in fuel system- turbo needs service- poor injection due to injector tips wear down- bad quality of diesel- over loading of the car- lack of control sygnal on the injector solenoid coil-- etc- etc Quote Link to post Share on other sites
