After a long drive engine felt rough,

Then engine warning light came on. Then some miles on the engine stopped. Breakdown service diagnosed injector 4 failed. Got the car to a garage. All 4 injectors replaced, not cheap. After a short run engine failed again. Injectors were checked by a specialist, found metal contamination. The entire fuel system is contaminated. Cost to clean and repair parts is now more than the car is worth. It’s likely the HP fuel pump failed. Has anyone experienced this? What did you do. Car is heading for scrap now, very sad. Car has done 150,000 so I expected to change injectors but not this.

Thanks

Says who?

How can they tell?

It is possible but I haven't heared of this happening unless fuel was contaminated with water or pump run dry.

Maybe poor bleeding procedure? Id be curious if the initial garage had anything to say about what they found when replacing 4 injectors. Why did they fail?

How much to replace HP fuel pump?

Injectors may be salvageable? Unlikely but worth checking

Thanks for the comments. Original failure was injector 4 siezed open and then a drop in fuel pressure.looks like the hp pump could have been overworked and failed. I’m sure the injectors could be reconditioned at a cost. I could still spend thousands sorting this to what end I don’t know. I really asked the question to see if anyone had this kind of experience with this engine. Thanks

Similar issue on mine. I put my injectors into diesel specialist who cleaned them and tested them. Hp pump replaced for 500 recon'd and full clean of fuel system. New filter and car drove spot on. Mine was a 18 plate

Thanks for the reply, I was beginning to think it could only happen to me! What did it cost to put right? The garage dont really want to do the work saying its uneconomic as the car is only valued at 4K now. The risk is more problems after spending a bunch of money on it.

I had already spent money on the injectors. Reconned fuel pump was 500, and it was another 480 to do it (approx a day) all the fuel lines, rails etc and the tank had to be cleaned. Time consuming - diesel specialist adv me to run it into we buy any car and cut my losses right enough

tank had to be cleaned

I doubt that. Unless contaminated by alot of water.

You'd reckon the filter would take care of any debris in the tank

Can only go on what my experience was

Whats your car worth as scrap? & whats to say any replacement car wont have an expensive issue? A friend bit the bullet and replaced the fuel pump and injectors on Fabia Diesel, that was 30k ago......he had run it out of fuel more than once!!! if the work is done by someone who knows what they doing, it should be fine, your garage sounds like they don't want to do it........ No real need to clean fuel tank unless its been filled with petrol or poor quality fuel. As these engines can do v hi mileages with out issue, perhaps yours have been run dry, filled with petrol or never had filter replaced/not primed properly.

Thanks for the reply, you are right the garage does not want to do the work and I dont want to pay for another set of expensive injectors either in case they fail again. No dodgy fuel however costs will quickly exceed the car value. Its a sad reality

Alan, You've clearly had a bit of "bad do" but if you like the car it doesn't really matter if repairs cost more than it's worth. It's the replacement cost you should be comparing the repair costs to. I spent many hundreds on my old 2008 Octavia until it became untenable because of the need to go into the London ULEZ quite frequently.

In many ways I still regret selling it because its replacement ULEZ compliant vRS has been an absolute sod.....

Yes i get it, mine, a 2016 plate, is on 140k, still on same clutch, as i ve had car from new.... a new clutch and fix leaking cam cover and replace injector seals is close to £2k.... should something like a DPF or worse go and the car becomes uneconomically to repair... mostly due to labour costs which have become ridiculous.... but one does need to look at the replacement car costs and that any other vehicle will also have costs... my plan is to keep this one until it cannot be repaired, touchwood been v reliable, rad aside, the slight oil leak has been apparent for 4 or 5 years... nothing has gone wrong other than serviceable items.
