Hi. I know here is so many posts about this problem but just can not sort my one.
I've got mazda 6 2006 2.0 diesel 143 bhp.
Took it for oil change to local garage. 400 miles later dpf light start to flash and 30 sec later eml as well. Engine in to limp mode.Tried to reset it connecting pin in fuse box according to tricks and tips website. Done everything as it says. Glow plug light flashed as it has to. But bloody dpf and eml still on. Took it to another garage. Mechanic plug it to his computer and said dpf need to be cleaned. But he run the car on first gear on high revs and got my power back but still with dpf flishing light. Unfortunately 3 days later car went back in limp mode. So I took dpf of and clean it. Loads of black rubbish come out from it. I fix everything back tried trick with pin again. Glow plug light flashed as it has to. But unfortunately nothing changed. Just don't know what else to try. Mazda garage will charge loads of money for visit to them.
