Hi All,
I have a peugeout 3008 1.6 ehdi diesel, 2012 plate with 150k miles. A common problem are the diesel injectors failing and need replacing. One of my injectors have failed so what's you opinion on:
1) Buying OEM (very expensive) or buying aftermarket (much cheaper)
2) Just changing the faulty injector or replacing the whole set
3) My mass oxygen sensor meter also needs replacing. Again, OEM or aftermarket?
Thank you for your help in advance
Always Stick with OEM Stuffs (Peugeot Genuine Parts) when you replaced Fuel Pump, Fuel Injectors, Fuel Pressure Regulator, Catalytic Converters and any kind of sensors Stuffs (including MAF Sensor, Oxygen Sensor, etc.)
And also change the Fuel Filter Extremely Very Conservatively on any kind of Diesel-powered Vehicles
When you do replacing the Injector, replaced them all at once along with Fuel Filter and do both Fuel Pump Pressure and Volume test before you decide to changed the Fuel Pump along with Fuel Pressure Regulator
Whats the difference in price between OEM and the Aftermarket injector off hand ?
£100-£200 for aftermarket vs £350 OEM
Wel...heres what I think..You have a suposed one injector problem. Okay if you buy the one after market injector...HOW bad could it be as opposed to the suppose bad injector now in place..? It's a gamble of sorts but worth a try in my book. If you install the new injector and NOTHING changes then the original injector may still be good..of course the true test would be to swap it out for another and see if the code changes to the new location. Other may not agree to my strategy and I'm not saying their wrong either...its just that sometimes HOW we get their is on a different path...as long as we get to the right fix..all is well.
Insanity is doing the same thing over and over and getting the same result. Throwing parts at it will never cure the root problem.
If the OEM injectors keep failing....replace the failed one with the cheapest available.
Then research and find why they keep failing...do they fail electrically...because of too high voltage, too long/short of voltage pulse (injectors don't get constant voltage, only a small pulse each time they are to function), or are they failing mechanically due to debris is the fuel system or other internal mechanical issue ?
Diesel injectors are lubricated by diesel fuel. Infrequently used diesel engines can have injectors and pumps seize internally due to lubrication (diesel) running off and high humidity causing rust. It take a microscopic bit of rust to wreak havoc.
Poor or contaminated diesel fuel can cause issues...again, poor lubrication. USA sells ultra low sulphur diesel fuel. Sulphur is a lubricant. The result is called "stiction"...poor lubrication causing tight tolerance components to stick (seize). There are additives for that problem.
For the most part, the aftermarket does a good job on fixing the problems of OEM specs.
Generally speaking, for crucial components, If I am 100% sure the aftermarket part is the OE maker, I go with aftermarket. But sometimes I don’t have enough info, so I bite the bullet and go OEM.
