Hi all,
Yesterday another dealer managed to diagnose the care (not that obvious, it's been converted to LPG, mototmanagement does not respond without certain measures) and the airmass sensor was replaced. It runs perfectly on fuel now but the LPG system keeps on giving the failure led and switches back to fuel. Question that remains is if the airmass sensor got worse slowly causing the missfires. Diagnose did not give any other fault code so now I have to find out what the problem with the LPG is.
Regards from Belgium.
