Difficoltà erogazioni bassi regimi

[Pavide]

Ciao Ragazzi,
Sono alcuni mesi che ho parecchi problemi con la mia golf...
Circa un anno fa ho montato l'impianto a gpl BRC (iniezione gassosa mista, 80% gas e 20% benzina) sulla mia auto e, dopo circa6 mesi sono iniziati i problemi.

La prima volta, entro in autostrada e affondo per superare un camion e parte spia motore ed EPC tagliando potenza e costretto ad accostare, dopo spento e riaccensione, torna ad andare tutto regolarmente ma con spia motore ancora accesa.
Vado da chi mi ha montato l'impianto, amico di famiglia, e verifica delle mancate accensioni.. decidiamo di cambiare le candele e se spariva ma invece, da allora, sempre peggiorando, la macchina ha dei vuoti di erogazione, anche al minimo, e spia motore lampeggiante.
Così decido di lasciare l'auto in un service vw, auto ancora in garanzia, e dopo varie prove non capiscono il problema e mi consigliano di sostituire testa con valvole o l'intero blocco motore... stesso discorso di Ospite per intenderci...
Però, visto che ho l'impianto, loro non intendono far nulla in garanzia... ritiro la macchina e, visto che il problema sembra essere calato, la tengo cosi finchè non ho news più serie.
L'altro giorno ho fatto un check della centralina col cavo VAG e infatti ho notato questi errori...
