Hi,
I recently posted a newbie post and asked about Trajet error/trouble code u0d00.

Well, through a process of elimination I seem to have tracked down the fault. Whether or not this is the code for that particular fault I don't know, but the fault is fixed and all is well after a LONG trial and error day.

Fault Code (error Code or Trouble Code u0d00 was showing on diagnostics but no reference to this anywhere.

Trajet 2.7 V6 Petrol with LPG conversion. Idlle on LPG was lumpy. On petrol much worse and spluttered and backfired, could not pull itself along. On open road at revs the LPG performance was about 80% but petrol bad. On level it would barely hold revs but no power or acceleration. On incline just slowed down and died as if petrol blockage or similar. Replaced Plus, leads petrol filter but nothing at all made difference.

Last resort unplugged the Mass Air Flow meter cable and car ran perfectly on LPG and petrol. replaced cable and it died again. Don't know if the u0d00 code is relevant to this fault but it certainly was the problem on my Trajet.

Mass Air Flow meter replaced...like a new car again! Thanks to anyone who tried to find out this fault code.

I hope this info is of some use to other Trajet owners in same situation.
