Does this sound right?

Hi all, not much experience of modern diesels but my mate has a 2011 Diesel Honda Accord, it was running badly so he took it to a Honda dealer and they said the injection pump has gone rusty and this rust has destroyed all the injectors.

Quote for repair:
Injection pump - 1500
4x Injectors - 1600
Labour 6 hours - 360 (Spanish rates cheaper than UK)

Total cost 3460 + VAT = 4,200€ so just under 4k GBP

Does it sound about right and is it worth shopping around for those parts or are they just generally very expensive components? Also will all four injectors definitely be destroyed by the rust. I'd normally say he need sto avoid the main dealer but if the parts prices are that expensive everywhere he won't save hardly anything paying 40€/hr + VAT at a normal garage instead of 60€/hr + VAT at the dealer so might as well just do it there...

Don`t know how the inside of an injector pump can go rusty , unless the car as sat for years and moisture has built up internally causing the corrosion.

I would imagine that pumps + injectors can be rebuilt by a specialist and fitted by a local garage , you may not save money in labour costs but he certainly will on parts.

FWIW i would always seek a second (third) opinion before making such an expensive decision.

Thanks, I'm telling him to get 2nd/3rd opinion - but he's an "always use the official garage" type of guy and needs his car. I think he's only not gone ahead with it because he doesn't have the money so it's a bit of a hard sell so I want to advise him well. Myself, I'd get a second or third opinon becfore spending 120 quid on two tyres!!!!

Apparently it's normal for this - the translation of the problem is "metal corrosion/filings", so maybe not "rust" but some other type of corrosion or wear? For sure this guy would only have ever used pump diesel and not veg oil/unknown water content stuff like I do. He also uses his car every day or weekly at least and does big mielage (15k miles pa) so it shouldn't be from moisture through underuse...

I was interested so did some Googling,seems poor quality fuel and/or repeatedly running the tank to nearly empty could be a cause.
Something for all you oil burners to remember,try not to let the tank go to less than a third full.

But surely the fuel filter should be stopping all of this crud getting into the pump.

The pump disintegrated and put the crud into the injectors... Or atleast that's what Honda said. It's the crud from the disintegrating pump that's the problem, not bad fuel. I suppose the question is what caused the pump to disintegrate in the first place but I got a quote for him from another garage and they said it's quite common for diesel fuel pumps to break at 100-150k miles.
