    Default Do i have manifold flaps ?????

    Good evening boys and girls, i have a 1.9cdti 120 bhp siggy with the following fault code P1901 i have had it on my snap on scanner and it says excessive differential pressure tried no end of times to do a regen went all the way on holiday a couple of weeks ago (120 mile) to campsite in 3rd gear light didnt go out until a stop start (strange i thought). Then on the way home a week later the light came on again with the same fault code, i was thinking along the lines of the pressure sensor but i have asked a VX tech, as i am a skoda tech what his thoughts are and he said the manifold flap will cause this fault, but i was under the impression that onl the 150's had this problem? am i right or wrong i don't know?

    sounds to me like the dpf is blocked & may need more than just a regen

    i've had the dpf soot accumulation checked and that was only 14% so it cant be blocked but i am glad i dont have the flaps, i thinks its time for a remap,
    Oh i forgot to mention i above post i have a tuning box would that cause problems ? i know i am about to get slaughtered but hey ho

    the tuning box could be the clogging of your dpf, the only way to tell for sure is remove the dpf & flush it clean
