This is schematics to inspect and check wiring and check solenoid and component locations Newer purchase parts before you do diagnostics and inspection of wiring
Hi, i have a 2003 volvo d12 465hp Mechanics said that wiring is getting signal but has an X on solenoid. I have code mid 128 ppid 123 fmi 5 and Mid 128 ppid 124 fmi 5
I wish that volvo wants to give me parts numbee i would replace both epg parts find some aftermarket becouse it is to expensive in volvo.
After months of a couple psi of turbo loss, and a squeaking engine brake, loss of fuel mileage, I finally figure out it must be the epg. My fan clutch has been squeaking as well recently. Yesterday it was raining and I went to use my engine brake to slow down on an off ramp and it just sounded like air with water rushing through it. I then went to leave and I was down below 10 psi turbo and no acceleration at all. I guess this is my epg stuck closed? The psi would eventually return to around 18 psi and have some power but i used to get 30 and had been around 27 for a month. The epg parts are really expensive on this. Is it worth trying to clean it? I havent found any aftermarket at all. Epg 20722238 06 volvo d12. $1000, valve $600... if i block off the intake i just lose my level 1 exhaust brake? Apply air pressure to get it fully opened? Thats what ive gathered reading all these posts. Any help appreciated.
