merhaba arkadaşlar aracımda bir hata veriyor yazılım var aracımda stage 3 downpipe var .bu haliyle n75 i baglayınca arac direk limp moda düşüyor 0.5 bara .bu sorunu aşmak için bende mcb kullanmaya karar verdim.mcb ile 1.1 basınca ayarladıgımda arac gayet saglıklı yuruyor ama şöyle bir sorun oluyor.Araç 1.1 dedikten sonra 1-2-3 viteste 4500 rpm i geçtikten sonra 07 bara kadar iniyor.vitesa attıgında 1.1 den başlıyor yine ama 4 viteste 1.1. basınca oturup gidiyor düşme olmuyor.aracın wesgate hortumunu söktüğümdede yine 1.1 bar basıyor ustunu basmıyor.hava kacagı aradım ama bulamadım.elm 327 ile lft ve sft degerlerine baktım ikiside 0 hava kacagı olma ihtimali cok az.maf sensörümün fisini çektim rolanti saçmalaması dışında halen aynı gidiyor.elimde volvo nun orijinal arıza tesbit cihazı vida da var onla baktıgımda ECM-6806 hatası veriyor.gazlamadıgım sürece hata vermiyor ama sıktıgımda yine aynı arızayı yazıyor.bu basınc düşmesinin sebebi nedir.birde bu hata koduna baktıgımda olasılıklar sunlar dıyor vida
284: ECM-6806 Turbocharger (TC) control system flow fault. Flow too high/low. Permanent/Intermittent fault, B6284T
Diagnostic trouble code (DTC) information
Condition
If engine speed (RPM) is above 3500 rpm and the engine is operating at a high load, the control signal to the turbocharger (TC) control valve is at maximum and the boost pressure (from boost pressure sensor) is lower than a designated value (approximately 20 kPa (2.90 psi) under normal boost pressure - signal too low).
If the air mass (from mass air flow (MAF) sensor) is higher than a desired value (signal too high) it is interpreted as a fault and diagnostic trouble code (DTC) ECM-6806 is stored.
Substitute value
reduced boost pressure
Possible source
Signal too high:
-air leakage after turbocharger (TC)
Signal too low:
-hoses between turbocharger (TC) and turbocharger (TC) control valve respectively turbocharger (TC) control valve and pressure servo are loose or are blocked/damaged
-faulty turbocharger (TC) control valve
-faulty boost pressure control (BPC) valve pressure servo
-sticking boost pressure control (BPC) valve
