103kW/125kw TDI PD Piezo Siemens injector failure thread

[Greg Roles]

Please see my latest post #248 in my "serious" thread", I fitted my UK sent "improved" loom tonight, and it was a mission. The Audi sourced code earlier on in this thread is a DIFFERENT part in several ways, and whilst I managed to get it to work, it's obviously an Audi or at least UK specific part.

I'm still glad I did so, for whilst the wiring insulation wasn't as hard as I expected, it certainly wasn't new, and was quite faded, and my old loom was early 2007, and from what we know to date, definately in the era of failing parts.

I took video of the process, but will hold off putting it together, as this isn't something I recommend people do till we find the reason for the pretty considerable differences in looms.

A copy of the UK VOSA letter going out to UK Audi owners....

I like the point 2. in that letter.

...and if VAG group here do something similar, I'll let it be.

I have a 103TDi golf V 106000km, extended warranty ran out 3 weeks ago. Car flat bedded to dealer on Thursday night after stopping in peak hour traffic. It will start and run for about 10sec and stop again. Late Friday I’m told it is going to cost me ~$4800 for 4 injectors and loom.

The 103kw runs the Bosch system, and it's much less likely these will fail, unlike the Siemens in the PD170 / 125kw this thread is mainly about. Bosch parts are available individually, so that is a plus. If you have dealer history on servicing I'd like to hear how VW can argue it's your problem entirely, as the injection system is a NON SERVICABLE PART, and could be expected to last a reasonable lifetime in an engine, say 250-300kms? I'm sure a lawyer could easily argue that in small claims. In the least VW should come back with an offer to part pay ( take the hint VW ), but so too I'd be going straight to VW head office, who are all too well aware of the injector problems out there, and bring their attention to all the things mentioned in this thread, the facebook page, you name it.

I'd be suprised if you car does in fact need all four injectors and loom, that is usually more the Siemens approach, but it may be that the 103 has failed in enough numbers for VW that the only fix is the same "replace it all" solution. Be nice to be able to get the exact fault codes out of VW, but of course they want to keep these issues as quiet as possible to prevent having to payout on their manufacturing flaws. See what they come back with, be nice to hear of them doing the right thing up front.

Of course Greg, once the car is out of warranty they will push to replace everything that may be affected by the fault or cause it (even by a small chance), but hey should it be under the warranty you could straggle to convince them to do the same.

On the topic "reasonable fuel injector life"; I think it is an uncharted territory and you can forget about, that in the past injectors lasted a long time.
1. The diesel fuel has changed and is not the same as in the past.
2. and obviously, it is not the same injector as in the past, so the manufacturer could argue that ever increasing demand on a clean air forced them to speed up some technologies (some invented 1/2 the century ago).

Of course that repeated fuel injector failures before your car reaches 150,000km or even better, well before 100,000km as we see here is not acceptable and VW knows it. I just saw that someone was told that there is 7 Years warranty on the replacement injectors. http://www.vwwatercooled.org.au/foru...tml#post703547

Thanks guys – Austral are addiment that all 4 should be replaced at a cost of $4977!!
Injector to be used is 03G130073GX – so not even a new part. I asked if my car had a bosch system and was told “No it’s genuine VW” – haha. I think the people making the recomendations really don't know about any differences between the 2 (bosch v Siemens)

I’ve contacted VWA and a case has been raised with their Warranty people, so it’s a waiting game now, we are in the position that we can get by minus a car indefinitely so I’m not rushing anything.

[Greg Roles]

I'm watching this case with great interest, be really bad news if the 103 injectors start falling over as well, far more of them out there than the already cursed 125 PD....

There has been at least one other 103kW PD failure reported in this thread
