This is actually a good news. would you mind sharing their contact details here so others can also benefit incase they run in to inevitable injector issues.

My 2016 duster awd (32K) on a drive from bangalore to pondicherry (over the weekend) - started throwing warning lights (attached images). The warnings went off and came back intermittently, and the engine pickup started becoming sluggish in 5th gear between 50 -70 kmph. Without any option we ambled for 100+ kms and reached renault vellore. They diagnosed it as a fuel injector failure and it needs to be replaced (28k) further they recommended to get all the other 3 injectors overhauled, get the diesel tank cleaned and the diesel filter changed (total 55K repair). The overhauling and diesel tank cleaning was a 48 hour downtime, so we got the diesel filter changed and the single injector replaced (spent 30K :sadface under running repair).

I had recently filled at a HP facility and i was told the contaminated diesel and the diesel filter that was not changed in the last PMS were the culprit. Now i am getting conflicting recommendations, my local Renault Service is saying the injector overhauling and diesel tank cleaning is not needed, just only put Shell premium diesel and it should be fine.

I asked about diesel fuel injector cleaner to be used and the service center is recommending against it saying it might lead to some premature knocking of the fuel. Any suggestions from others on what preventive maintenance to undertake, sure do not want to shell (3 X 30K) for replacing all the injectors.

Hema diesels contact number and address is available on google maps (099802 00839)

I would not recommend to change the injectors if there is no warning light coming in the car. Hema Diesels in Bangalore is one option where you can get the injectors changed or repaired at cheaper rates (new one costs 20K instead of 28K and if repair is possible, it might be even less). The Renault ASC will usually go by the company recommended measures and will probably cost us more.

One other alternative is - diesel additives for injector cleaning - specially when you go out of station and are not sure about the fuel quality (have not tried this but they seem to work from what I see in other reviews). There are multiple options for this and can be looked upon by simple google search.

Why the injector problem is so common across 110PS variants? What is the reason behind that?

There is an inherent faulty wiring harness issue on some of 110 ps dusters/terranos but renault/dealer are minting money by not replacing the wiring harness. Have heard multiple instances where people have reported multiple injector failures (check Samba’s duster thread and many more) where after replacing the wiring harness the issue does not pop up.


Shame on Renault/Nissan on not doing a vehicle recall and fixing the wiring harness issue. I am in a group where multiple owners have fighting it out even legally.

It seems the wiring harness is the culprit. I feel the Carmakers must have recalled the vehicles.

I've been looking at pre-owned dusters (110ps and AWD). The car seems to meet all my requirements (ground clearance, boot space, decent power, driver leg room for tall people). Most cars have run around 70-90k kms. Should i go for it? Is there anyway to know if i will run into problems? The inconsistency and sudden nature of the issue worries me

Bumping up old thread

Is there any particular series of K9K engine that is more prone to these injector issues?
I recently purchased a diesel Kicks which is based on the Duster. SA at ASC told me that injector issues occur rarely in engines manufactured post 2018.
Engine number of my car starts with K9kR856. I think first lot of Duster had engines from R832 series.

Any help would be appreciated.

Thanks Naveen, I'm having a 2017 Renault Captur, again with the same 110 PS Diesel Engine as in Duster. I got the "Check Fuel Injector" Warning lights first in Feb 2022 on my way from Bengaluru to Hyderabad at 10:00 pm in the night between Ananthapur and Kurnool. Not to mention it was an adventurous night with my wife and two boys.

Initially it was a warning light which soon turned into "Engine Hazard" Red light. We towed the vehicle all the way to Ananthapur at midnight and got the fuel removed and fuel lines cleaned the next day to remove the alert.

After that episode, all was good until we were on our way to Chikmagalur and Jog Falls and we got the same episode near Hassan... This time we ignored the warning and drove on and the lights cleared on by themselves after a while. Had similar incidents on my drive to Kanyakumari last year and a few times within the city as well and we ignored everytime.

Again got this issue yesterday, but this time the engine firing is not proper and the vehicle is sounding like a truck... So logged onto TBHP and saw your message regarding Hema Diesels... Just spoke to Kumar and asked him to send someone with the scanner and a spare fuel injector. I thought I might as well keep a spare injector and learn how to replace it incase this is going to be a recurring problem... Let's see, he said he is arranging to send someone to my place... Will keep you guys posted...

Thanks and Signed the petition as well. Can someone add my number +91-9902156979 to the whatsapp group for the Renault 110 PS Fuel Injector Problem... Btw, I couldn't find Samba's duster thread regarding the Fuel Injector issue...

I'm now wondering the same. I think replacing the wiring harness is possible. Checking the service history for any potential injector replacements might give some idea. The awd is definitely the best duster option especially with the retuned engine.

Been researching about the Renault Duster 110 PS specifically across all forums in India and Abroad for user experiences and known issues. Based on this thread I understand injector failures are more prone to happen on AWD units. Mine is a 2013 Duster 110 PS FWD. I had the Injectors serviced 2 months ago as a precaution since my Duster's done 1.8 lac kms then and the service advisor who I happen to have a decent rapport with suggested this. I once accidentally noticed white smoke when I was backing up on an incline in seconds after the car was started up. The injector repair reduced the problem but I am sure it was actually a dead glow-plug on Cylinder 1 which I also randomly checked while I was doing a thorough Engine Bay cleanup and checkup.

A quick note, if you remove the injectors on the Duster and put them back, coding is to be done whether you change the injector arrangement or not and also more importantly reset the C2I Adaptives as it clears the Injector Needle Pilot Qty and ensures they're adjusted and learned in realtime as you drive. I hadn't done mine immediately, but when I did do it approx. 5000 kms after the Injector Service on the bench, my idle injector knock reduced to almost 95% and sometimes its not even there.

Other thing regarding why my injectors could have lasted longer is that I ensure I filled up at a specific INDIAN OIL only pump whether am in Mumbai or Pune. Even if am travelling out of state, INDIAN OIL diesel has proven to be better ( even cab drivers agree here locally ) and Add-On or Liquimoly Diesel additive is never skipped. I avoid filling up till the additives are in the car and keep them stocked.

Additives are expensive but affordable, Injectors are even more expensive and certainly not affordable.

Here's my experience with my 2013 Duster 110 PS ( FWD ). Its been run for 11 years and 1.91 lac KMS. The car has had no issues till it was used regularly and serviced as per schedule. But not only that, the car was always fueled up for regular Diesel at only an Indian Oil Petrol Pump. Same pump in Mumbai (Kandivali) or Pune (Sinhagad Road). No other locations. And at all fills, Add-On Diesel or LiquiMoly Additive has been used. I can only guess this is why there hasn't been an injector failure on mine. Even if am driving outta state, I plan such that I get to fuel up at Indian Oil's bunkers only.

I had the injectors serviced 3 months ago at 1.80 lac kms based on the advice of a Renault A.S.S. floor supervisor who I had a good rapport with. There wasn't any issue going on with my Injectors but he still insisted I do that for a better life.

He added, Injector Failures are often pointed out to running fuel levels very low. Not sure why but the Continental Diesel Pumps run hotter at lower fuel levels and start eating themselves up from the inside and send debris into the injectors which cause all sorts of malfunctions affecting the Pumps and the Injectors. He showed me the temperature difference in the CLIP Diagnostics tool too as the car with higher fuel levels had lower temperature of fuel and low fuel capacity car had higher fuel temperature. So I ensure my Duster never ever sees a Reserve light and it rarely has.

Based on this thread, I understand that injector failures are more prone for AWD models than the FWD and even on YT, K9K Injector failures are almost always for Continental units itself. And its usually recommended at high mileage to replace or service all injectors.

Another interesting fact. Whenever a Fuel Injector is removed from the vehicle for inspection or service, they need to be put back in and coded even if you don't change their arrangements. And not just coded, the CLIP tool is to be used to reset the C2I Injection parameter adaptives to clear the Pilot Qty of all injectors. I noticed that my Injectors knocked at idle after they were serviced. 5000 kms after service when I did the Adaptives reset the injectors stopped knocking. Idle knock is now only 5% of what it used to be.
