Civic 1.6 i-DTEC injector failure

Hi. This is my first post. I have a 2014 Honda Civic 1.6 i-DTEC, ive owned it for 18 months. Previously i have owned a 2011 2.2 diesel, since changing to the newer 1.6 i initially thought it was less responsive and powerful. Over the last 6 months i have gradually noticed it has been getting less responsive and the fuel consumption has increased.
last month it was booked in for a service and on the way the DPF warning came on. The garage carried out a DPF regeneration along with the service and MOT, they advised me the car sounded noisy and suggested it was a diesel combustion noise possibly caused by worn injectors.
Two weeks later the DPF light came on again! This time i went to my local Honda dealer, they carried out a forced regeneration and told me the engine is noisy, they have carried out a few tests and suggest the injectors are worn.
The dealer has quoted just over £1400 to supply and fit all 4 injectors and have told me the DPF could be ruined, costing eye watering amounts.
This is something concerning for a 2014 car with 85000 miles.
I have taken the car to a local garage and they have advised me to get the injectors reconditioned and the DPF removed and flushed/cleaned by a specialist company.
The DPF has been removed, sent away and returned back ready to fit.
The injectors and have been sent to "the best diesel specialist in the country" and they have contacted me with some bad news!
The rebuild kit and nozzle that is needed for the serial number/model of injector for these engines is not currently obtainable from the manufacturer. They have had on average 2 sets of these injectors sent in a month for the last year with the same problem and suggested there is or was a design issue with these units.
He suggested to buy new genuine units from Honda as by experience they can be obtained quicker than ordering through him and theres no real price difference.
I asked his opinion on fitting second hand ones as they can be found on eBay for £70-£80 each. I was advised not to do this as it could be a waste of money, they have had people buy second hand ones off ebay, send them to be tested and they are far from perfect. It would also ruin the DPF too.

So, has anyone else had the same issue with 1.6 i-DTEC injectors and what did you do?

I'm sorry that it's not going to answer your question, but what kind of noise/symptoms did you experience? Mine makes quite a racket sometimes on startup but goes when I rev it and also in the heat the car stutters a bit under light acceleration

Shaintaylor.
From speaking to my local honda dealer there is a common problem with 16MY 1.6 I-DTEC engines. the cam shafts wear and have excessive end float causing a rumble noise on start up and low RPM's.
My vehicle has a diesel combustion knock when puling away and under load, its noisy when starting too and it stutters and surges when trying to pull away from junctions. it has slowly progressed and got worse it sounds like a little end knock.

What sort of Mileage and Journeys are you doing out of curiosity?

Can't offer any help on this but this doesn't sound good. Have you been in contact with Honda UK customer services about it? Bypassing the dealer.

Bog standard diesel is the minimum required, buying anything more expensive is a waste of money.

Would you be able to take some videos to compare against mine? Mine is a 14MY with 120K on it, it has made the cold ticking since I had it but has only started spluttering when accelerating since the start of summer... When yours does splutter and surge, does your engine make a rattling noise until it stops? I'll try and get some videos of mine.

Would also be able to describe this rumble when pulling away and at low revs? As I have a new vibration coming from the engine when accelerating but it will be hard to capture on video....

I'm starting to regret trading the 2.2 for this now...

Sorry i cant take video, its currently got the injectors removed.

I was hoping other people had known about this issue and may be able to recommend somewhere other than the dealers for new injectors

That's why I said contact Honda UK direct. In my experience, they take reliability very seriously. See what they have to say. They may even offer to help you with costs as a goodwill gesture.

They don't take their servicing serious. Honda Dealer and Honda UK thought this still had another 3K in it...

Ive spoke to Honda UK on the phone, because my vehicle does not have a fully stamped service book from a honda main dealer they will not offer to help.

I have just bit the bullet and have ordered a set of new injectors as i need the vehicle back on the road.

The new Injectors have been fitted and the car sounds and drives a lot better. It's like a different vehicle!!

Not as bad as i first thought as the garage that did the repair got trade discount on parts. the total with the labour was £1340.

Typically as luck would have it i have since found a set of 4 on eBay that are "as new" and a lot cheaper

Wow. Why the hell are the injectors so expensive. I had a couple changed under guarantee on separate occasions on my 2.2 Accord and they told me the job was about £400 each.
Bummer finding those on eBay too late though.

Yes they are expensive. The ones ive found on eBay have been reduced now too, really rubbing the salt in the wound

On a positive note my car feels smoother, sounds quieter, pulls harder and the fuel economy is much better. Im very happy!!

Good result but at a high cost mate.. I always try eBay first if I need anything major. Half of my Mrs Fiat Punto is off eBay Best one was the throttle position sensor, actually mated to the throttle body and doesn't split £356 Fiat £10 FleaBay and 20 minutes to fit

Yes im actually annoyed at myself, I spent 20 mins every night for a week looking for some injectors but that are all used. typically after i bought new ones some came up on ebay that have only been used in a engine for a few mins. always the way

Don't you have to code the injectors though with the ECU?? Not just a case of replacing them from what I understand..
