Check injection and emergency run and FAP problems

hello, with my scenic II 1,9dci with 130 ps the problem, that this today as well as a few days ago with the report to check injection went into the emergency run. the first time the report went away after a restart, but today the report did not go away, but it came additionally the report FAP must be regenerated. because of the filter I went on the highway and drove forever with constant 120. after over 10km the emergency run and thus the report to check injection went away and after another 5 km then disappeared also the particle filter message. at the end of the tour there was finally no message available =) I would be interested, why does the current constantly check with the message injection into the emergency run? I thought of the glow pins, but the car starts immediately at the second turn, so I don’t know if it can be because of it. am really stunned:-( thank you already =)
