Injector cleaning

[LiamR172]

My brothers 172 was running on 3, turned out to be an injector so we replaced it with a new one, then another went so replaced it too..

And another has gone now so I'm guessing the 4th will follow.

Can we get the 2 faulty ones cleaned, how good is the cleaning service, will they be 100% working after cleaning?

Or best just buying another 2 new ones?

I'd buy another 2 new ones for piece of mind.

Yeah replace all 4 with genuine renault only from a reputable dealer, and maybe try selling the old ones to someone who wants them to clean them. That's what I did :up:

Something's causing them to fail

Once replaced fit an inline filter, job done

No idea mate but I'm in same boat and it can't be coincidence. Mines been fine for over 10 years then suddenly it's needed 3 injectors in a year.

Dirt in system, fuel filter, fuelling, lambda ?
