When i'm driving little bit faster, about 120 km/h then after 2-3 minutes i will get error message: "power reduced serv 45" and engine stalls, like one cilinder does not work. i turn off the engine and start it again, then engine failure lamp is on. but engine works well. if i drive above 120 km/h then everything is fine.
i went to service and they said, gas regulator ( i dont know how to name that part) and it will cost me 900 USD
service codes on my display: engine system serv. urgent 77 and engine system 44
volvo service error codes, after i paid 100 USD ecm-9150 and ecm-9160
can anyone help please? even if i need new part then probably its better to order it from US than here (Estonia).
I hope to get this problem resolved quickly
