Another Injector Thread / Question

A6 All/ S6 All
#1

Alright here we go. I just talked to my buddy who runs parts at audi dealer and used to own a C6 V10 also. He said the injectors FAIL and must be replaced, they fail un-related to carbon. Is this true?

I have almost everything ready to re-do my engine:

  1. Walnut blaster
  2. Walnut shells (fine grit)
  3. New IM
  4. On the way JHM spacers, SAI DEL, heater bypass, etc
  5. Have yet to purchase - O-Ring kit for injectors

I was planning to ship the injectors out to be ultra-sonic cleaned and flow tested. Now I am stressed that I need to buy new injectors.

What did you guys do?

IMO $1,700 for injectors doesnt make sense. Checking my repair history I see they purchased 06E998907 meaning the injectors are original when the put in the new engine 07l100031ax, I assume the old one blew up because of a failed injector (s)!!! :-[

I was getting some flashing CEL occasionally, usually the codes were for misfires on 8 and 4, sometimes 7 and 2, random, go away when warm. Also got some codes once while driving “hot engine” for P0171, P0174, P0175 “system too lean” bank 1 and 2. I assumed these all to be Carbon / IM related. I think some air may be sneaking into the IM through the broken IM flap hole…

I put in new injectors at around 80k miles. It fixed all misfires, which I had been chasing for a seeming eternity. Spent under $1k for 10 new Hitachi injectors (the OEM) on FCP Euro w lifetime warranty. When car gets to about 150k miles or so, I will do reseal like eng92 and get new injectors from FCP Euro under warranty.

IMO, if you’re going to keep the car, get new injectors. The oft repeated argument of JHM flow matching the injectors is not compelling to me. The cost of getting them cleaned is close enough for me that new makes sense.

Yea I assumed this to be the consensus. I will not cut corners. Ok so,

By chance, when you ordered these, did they come with the o-ring kits or should I purchase those as well / separately?

#4

I’m almost certain they came w all O-rings. Send them an email. They are very responsive. Also, mine were drop-shipped from Hitachi.

OMG and i dont ever say OMG!!! lol

FCP just lowered the injectors from 107 down to 83 each. Same price as rock auto!!

I sent the FCP guy on AZ a PM asking him to match the price and maybe that is why they are lowered?

Anyhow, money saved, lifetime warranty. My day just got a whole lot brighter :slight_smile:

  • Edit -
    Got a PM from FCP:

Peter,

We went ahead and updated our pricing. You will now see HIT-FIJ0033 listed at 82.99 each.

Best,

That’s a solid update there.

#7

Excellent news, and a purchase you won’t regret.

#8

Was back up to $104 per yesterday

#9

sell sell sell! who wants to invest in the fuel injector market with me? ;D

#10

I know right. What I have seen is that bosch injectors don’t seem to hold up as well as the Hitachi. The failed injectors are not just singled out to the 5.2 V10

#11

Interesting. In both cars i own (C6 A6 3.2 & the S6) they all had hitachi stock

#12

I removed all my OEM injectors and all were hitachi with audi logos stamped into them…
