Kog Posted July 15 Author Share Posted July 15 Hi catalyst symbol came up blinking then by time I got to garage stayed on so added some Dpf additive drove at high revs for 30 miles then cat symbol went off along with traction symbol now I’m just left with blinking glow plug light and after research and speaking to several mobile Dpf mechanics they suggest it needs cleaning so thought it might be worth a gamble at spraying some cleaning foam down wich ever pipe it is also change fuel filter to rule out cheapest first Quote Link to comment Share on other sites More sharing options...
