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.
