Hello, i have this Renault Master 2.3 81kw Sid321 ecu and i have a very strage problem with starter !
Errors on ecu : DF047 Power supply over limit
DF2002 Power supply under limit
DF007 Pressure valve line
DF1427 Bypass pressure valve
With ignition on the car does not supply ecu, and after a short on bypass valve the ecu is supplied and car starts!
