Injector Control Pressure too low
Hi Guys,
I have 2017 XC 90 D5. I was really delighted with the car until the engine cut out on the road a month ago. After cutting out the engine was turning over but failed to start after that. It has been in the main dealers since. The diagnostics computer in the show "Injector Control Pressure too low. *About 2 days prior to problem arising I noticed a very minor vibration/ struggle when the car was cruising at about 1500 RPM. It was enough that I noticed it but not enough to really effect the driving or cause me concern. No unusual engine sound.
2 Injectors were thought to be at fault but when replaced, the fault persisted. The other 2 injectors are now being replaced.
Question: Speed Test
1. Could all 4 injectors suddenly fail in a car with relatively low mileage of this age?
2. Is the car cutting out at 50mpg symptomatic of injector problems.
3. A non volvo mechanic (but highly regarded) suspects its no injectors but the fuel pump.
Any ideas/ views?
All help appreciated
