Injector help - Refurb of not!?

[Camperworx]

I have a 2019 T6, 2.0tdi startline.
Bought 4 x new injectorrs for my van and the mechanic installed them but the engine is worse than before.
On install, he said that the part number is grinded off the top of the injector and the=at they must be reconditioned. The supplier got really angry for me accusing me of suggesting that, and that they are new genuine injectors. But would the part number be ground off?

 

[St6]

The part numbers would be shown on each injector,as these numbers need to be updated using software to the engine ecu.if they have been grinded off then suggests they are not new .and you really need the numbers off injectors so they work properly.

As @St6 says, each injector should be coded to your particular van, did the new injectors come with the codes?

 

[whodat]

Could be that someone returned them to the supplier and even if they were checked by the supplier - at first glance they might have looked like they were genuine returns.
Still - doesn't help you.

No doubt they could have been returned prior to installation but now they’ve been used you can’t expect the supplier to accept them back.
As others have mentioned they need coding.

The deviation code on each injector needs setting in the engine ECU....

Something majorly wrong ig a grinder has been near them, recond or otherwise.

It won't run properly without the specific injector coding.

Who do you trust more, you mechanic or the supplier.?.... Without any proof either way looks like you have a problem.

Did you no let your garage source the new injectors?

Either way.... You need to have your original ones reconditioned.

Or buy another new set.

Bty.... Why? What was the original fault? HPFP failure?


Example below....

Can you get some pics of those injections with grinder marks?

Just for reference?

Quite normal for part number to be removed. Reason being, it'll be the genuine part but being sold under a different name.

I know my own injectors had the vag details removed, but are just genuine with out the VW tax!

We also see it on loads of other stuff we fit on all makes and models.

I'm sure a lot of the tradesman on here will see things like this too in their walks of life

So the adoption coding is still shown?

So you can still code them into the engine ECU?

What bit is removed then?

The part removed is the VWAG followed by the OE part numbers

Youll see from the pic below.

All coding numbers are still intact

Why the number has been removed appears to be cleared up. To remove it with a grinder sounds like piss poor workmanship,

 

[Dellmassive]

I'm being stupid, I still don't get it.

If the OEM part was manufactured by the third party company, ie Bosch or Delphi and stamped with all relevant information to be used as OEM for say VAG.

Why wouldn't they just produce the same thing but not stamp it with the VAG info and just have Bosch or Delphi info?

I'm don't get why they would produce a product and then remove the part number afterwards to sell at a discounted price through the patent part market?

I must be missing something.

Sorry this is just a side question and won't help the OP, I'm just curious.

Obviously @Dundee_Kev knows exactly what he's doing and sees this regularly,

The only time I've seen info removed is normally on stollen parts..... But we're saying these are not stollen parts, these are genuine patent parts from a reputable retailer?

 

[Sasquatch]

They probably sell it to the aftermarket for a similar price to that which they sell them to VW, but VW are greedy barstewards and will whack an eye watering mark up on the part because it's "genuine VW."

Meanwhile aftermarket sellers will still make a handsome profit, just not as anally invading as VW dealerships do, hence the price differential for the same item.

The VW mark up on parts is criminal. They get unpainted bumpers in bulk for less than a hundred Euros apiece and simply move the decimal point one place to the right when reselling.

 

[Bigsidavies]

Sometimes it's just the logo removed and not the part number. I've seen Pagid brake pads with the Audi rings removed and these are sold as OEM aftermarket, but at the normal aftermarket price, not the Audi eye watering price. That was years ago on my S4.

Isn't it just a simple case of cost and time spent on the production line?? If they need to alter the line and print so many without the oe details, it costs time.

Make a thousand and ask the oe how many they want, then Delphi get the left overs to do what they like with?

 

[Sasquatch]

Or maybe they needed a few to finish an order so took some VW branded ones and crudely did the deed? Whom knows?

maybe. . . who knows.

another one of life's great mysteries.


back to the OP.


@Camperworx - whats the update?

 

[DXX]

Maybe it’s the injectors that fail VW test parameters but still too good to re-work / scrap?
