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

[jazd]

I've found the guys in the UK are thinking it is the loom rather than the injector itself that shorts...but seems no-one is still sure what is going on. They are having the same sort of failures we are, cars dropping left and right.

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!

VAG 170 PS Diesel Injector Failures - VOSA action - BRISKODA.net - The Skoda Forum and Community

VRS TDI problems - BRISKODA.net - Page 2 - The Skoda Forum and Community

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.

In case anyone can read Romanian - here's their VW forums failure thread.....

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.

Touareg V6 TDI is CR.
