Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

    Have a few leads on refurbishers, but still awaiting an actual email response!! I'm hanging onto this like a pit bull - mainly because as of April I have no more warranty!!
    Bloody hell I hope mine doesnt **** itself. Counting on you to keep us informed

      My aim is to get an answer on refurbishment of injectors from the UK. If this is indeed really the case, then the problem isn't quite so scary. Most TDI's will be towards or into extended warranty now, and that only gives you a year or two more, so we need a solution to this problem. If this is indeed a possibility I will look into the loom on my own car, and investigate the possibility of a silicon insulated upgrade. I'm not venturing in there until there is a backup plan in place, no sense tempting fate!

        If there's anything the rest of us can do who haven't failed yet to get any useful data/observations, be sure to let us know!

          The size of it continues to grow...

          Anyone else with this problem on 2006 2.0 TDi? Injectors...

          on the upside post #27 does say that Audi DO replace the failed injectors with an upgraded type! Post #31 says a different part number for the upgraded injector.

            The Seat guys in the UK have their governments vehicle safety body on the case. Here's hoping some sort of response can be forced:

              I have gotten involved with several UK forums and they are starting to work together on their combined VOSA action. I don't think we have anyone to complain to over here beyond the papers / mags? I am going hunting on the Aussie sites next.....power in numbers!

              These two threads are very interesting reading, seems you can get a loom for $83 pounds, and an injector for $380 odd, FAR cheaper than here.
              Also reading this problem affects the 3.0 Audi TDI as well, seems all the high power PD pizeo injectors were Siemens, and flawed.

                  Hm, I think that so far there is no one who is too much out of pocket when the injectors failed. At least in our forum and if there would be someone, cold you please direct him to post his details in this thread: http://www.vwwatercooled.org.au/f28/...tml#post624276

                  IMO, as long as the VW fixes their injectors on the cars that are not too old (up to 160,000km or 8 years) when they fail, it's not much to complain about.
                  "The newest" technology could also mean "unproven" and lets be honest the manufacturers aren't only the one to blame for the components failures, they're pushed by the environmental laws to reduce the emissions to ridiculous levels, which means to come with the new technology that is not always reliable or has the problems at the beginning.

                    I understand mate, but I believe your Toureg may have these injectors too. Is it Siemens or Bosch ECU?

                    My gripe is the safety issue, read some of the tales from the UK. I don't expect free injectors, but it sucks people are expected to pay even a percentage for non serviceable parts that fail before a reasonable engine lifetime. It's not like it's rare, or only happening beyond 200k.

                      • ...with pizeo injectors I believe! It's the main thing stopping me from upgrading, but hopefully they are Bosch where you can get injector parts over Siemens where you can't. I'm sure they are upgraded, but I am still wary of pizeo technology!

                          I know what you mean. For the similar reasons I don't want to downgrade my T5 to the new T5 4 cyl twin turbo, because so far I didn't have any real failures. The new is not always upgrade to me.

                          Hopefully your injectors won't brake down.

                          • Greg, I thought you said that the CR injectors were OK, even if they use Piezo-Electric actuation, because the injector and loom aren't immersed in engine oil, which the PD injectors need to be.

                              Mark my words I'll be "that guy" when/if my injectors go - if my track record of getting things replaced under warranty are anything to go by.

                                Good point mate, but oil seems to be hardening the plastic insulation on the loom ( as you expect from long term oil immersion ) whereas the Pizeo component insulation seems to be more an internal design flaw. The parts theorised to fail thus far are totally sealed within insulation, and it would appear oil has no role in the actual injector failure from current facts available.

                                I'd think the new CR has better injectors, and the fact they have gone back to Bosh ( with all the spares ) is a good move, and that combined with a second generation DPF makes for a much improved diesel experience, but I'm still not sold on Pizeo technology until the failure mode is revealed.
