Hi everyone.

I need to replace some injectors on my Cayenne Diesel.
Any suggestions for part number.
I got quote from Porsche dealer and it is so expensive. Like $1200 each.

Thank you in advance.

I would suggest you ask the question at a VW dealer. Same engine in the diesel Touareg

I have the same exact vehicle, so following this thread... How did you come to the conclusion that you needed to replace injectors?
Can they be done individually, like replacing a single faulty one, or do they recommend replacing them all at the same time?

I've seen some areas for coding the injectors in my Launch tablet, so I guess I have one of the necessary tools if/when I have to take this plunge...

Keep us posted, as I don't see anything about this in the how-to area.

Not sure if this is the correct one, but maybe a start:

EDIT:
Porsche Factory part No (old): 95811012820
Porsche Factory part No (new): 95811012821

The part linked above shows an equivalency to the old Porsche part number. The new part number could mean lots of things, like a different manufacturer, or a different material somewhere, and doesn't necessarily mean a functional change.

EDIT2: BOSCH 0445-117-032 appears to be the generic part.

Assuming your car is out of the diesel gate warranty? If it is still in warranty, and you need injectors, they should be covered.

If you are able to have the down time, remove them, send them to an injector cleaner and have them calibrated...much cheaper than new...if you can wait.

This is interesting... Time to do some reading..

Or even better, an indie VW/Audi TDI mechanic. OP, maybe post your location and someone can make a recommendation?

Hi,
I replaced two of my injectors a few months ago as i was getting lumpy running with ticking and hissing from the engine bay which is indicative of the injector seals.
I bought Bosch Injectors which were £210 each ($285)
If you do this yourself you will need new seals, copper washers and stretch bolts (single use)
Pretty straight forward although some of the fuel line bolts can be awkward to access. Car is now running like a dream.

I also bought a few other bits to help with the job -

We have replaced 5 or 6 faulty injectors and glowplugs on our Q7 TDI under the dieselgate warranty. Dealership refused to replace any besides the one currently causing the fault, which was "Cylinder x contribution/balance" each time. A mechanic buddy with a TDI Touareg swears by a diesel additive that apparently prevents this from happening. I will definitely start to use that once the warranty is up (about 9 months left) but in the meantime happy to have it covered by the warranty. Price out of pocket I think would have been around 1700 each time

What's the additive he or she recommends?

It is Liqui Moly Super Diesel Additive. Can't vouch for it yet but after looking, I may go ahead and spend the 11 dollars to try some

I think I've probably put a bottle of some sort of additive in nearly every tank since I got the vehicle. I've always heard US diesel isn't up to par with the standard in Europe, so I figured I'd play it safe.

I'm currently using Stanadyne products:

I've been adding Power Service Diesel Kleen or Fuel Supplement (depending on the season....)

Ah yes, that is the other one I like to use since I can get it locally.. Good stuff.
