Help - metal filings throughout fuel system!

[MarkGArgyle]

Hi all,

Looking for advice especially from BMW dealership folk if possible. 2014 F31 320d, 66k miles out of warranty and BMW services from new. Long story short; high pressure fuel pump let go filling system with what I describe as iron filings, blocking injectors and causing a breakdown on Saturday. No clue why this happened and BMW confirm no outstanding recalls for this issue.

Car will be taken to my nearest dealer (60miles) for diagnosis but after the following;

1. Rough cost to replace injectors, rail, fuel pipes, tank etc at a franchise?

2. I want BMW to take (significant) responsibility for this with goodwill - anyone had this issue and result?

3. Best way to secure #2 happens (was looking at a <1yr X5 so already taking to the sales guy to support)

4. Any other advice to get it sorted for least possible cost with future warranty in the event that bits are missed and I have the same issue in a few month?

People of Pistonheads please help me secure my children get some Christmas presents this year!

Thanks

Mark

Thanks for replies and some good advice there; reinforces what I thought but good to know I am on the right track. Will come back and update how I get on for others.

Short update - fuel system is condemned and BMW want >£8k for replacing everything from tank through to injectors....

They will take a fuel sample for analysis and come back next week before discussing with BMW.


Merry Christmas

It’s normally the high pressure pump that starts destroying themselves and throwing out metal swarf - which is already after the filter - only place for the swarf to go is the common rail, reg valves and injectors.
They do have gauze strainers on the volume control valve and the pressure valve so would guess the amount returning to the tank and low pressure side would be quite small

This....

Suspect it is the HPFP which produced the swarf that blocked injectors and caused the breakdown in the first place

Final update; independent testing showed a problem with the diesel and as a result neither BMW nor insurance will cover it so it is out of my pocket. After a negotiation with BMW they knocked a grand off, will throw in the brake fluid service and gave me a surprisingly fun 118i for the duration.

Lesson learned, I would have been gutted if the insurance wrote it off as it is a great car with low miles so will just keep it for another year until the X5 comes down further in price or the new X3 is released.

Thanks for input all...

In regards to this and having the injectors replaced has anyone done this and the car run fine afterwards? I have the same issue with my car bmw want 10k to fix the HPFP went on me and now left with a price to fix worth more than the car.

OP here I paid approx £7.5k and it ran like new afterwards. Traded it recently for £10k with 70k on a 14 plate
