  • XC70,V70,XC90 D5 Diesel Pump expected life

How likely are owners going to need a replacement high pressure diesel pump for a d5 around 250k, assuming perfect service history?

What issues influence diesel pump life expectency? Frequency of Fuel filter replacement, Quality of fuel in ones area, secondary systems such as health of intank pump, Fuel pressure regulator etc?

Some believe its a life of car component. If Volvo builds the car to last for 7 years then many markets will be testing that assumption.

For example: The mechanical high pressure diesel pump (run off the crank) on a renault 1.5L dci has an average life expectancy of 180-240k according to internet lore and local turkish mechanics surveyed.
All in the quality of the diesel and if regular fuel filter changes have happened generally. Any known specific issues on the d5 pumps anyone?

I haven't heard anything reliable no.

Its not hard to find reviews or customers reporting on bad experiences with dealerships or models of car. The full facts are almost never included so we hear a component fails regularly without seeing a fullservice history. eg: I had a 'make/model' and the transmission kept failing (neglecting to mention he hauls a 2.5 ton boat ever weekend)
I have replaced a few lift pumps this year on xc90 d5's. Sometimes the wiring in the sender burns out, other times the pump loses flow and cant keep up supply to the high pressure pump. That said, it was not on any regular customers cars so unsure if maintenance was correct or maybe they run the tank almost dry regularly. We change the fuel filters at 45k.
I have yet to see a high pressure pump failure. Its important to prime the high pressure pump when you change the fuel filter as most damage occurs when the high pressure pumps is run dry
Running petrol by accident is a killer of any diesel pump. Followed by bad fuel. Most car diesel owners don't get the shitty low quality diesel from an old servo. More with small trucks. Filtration is important and depending on area the fuel tanks can just be old and rusty.

Otherwise, injectors are more likely to age and die.
Is it difficult to delete the swirl flaps.

Are they as pointless on an xc90 as they are in BMWs?

Will they cause catastrophic engine failure when they go?
Legally no. And egr is not a huge issue. Just a maintain item.
They don't fail like the BMW thank God
You can remove them but it's a bit different and not as easy, my vote is just fix them as they don't fail that often and it's not that expensive

Egr is an easy clean once a year thing (I do mine on Australia day each year now)
