Hello. I have problem with peugeot 508 1.6hdi 115km 8v, after change bsi and ecu, i wrote the correctly vin number and injector codes, but engine making noise and much more consumption have from before, in diagbox i found learning injector and i did few hundred km and is this same problem, when i look in diagbox info last learning is from 200000km ago, and still need a learn, maybe it is problem becouse charging voltage is not this same all the time ?
