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

Great post harlie, well researched.

Awesome post Harlie, thanks for taking the time to put it up. The more knowledge we can gather, the better.

...but to be fair mate, pizeo is new technology really, and putting that part into oil has been the problem. I would expect current pizeo injectors to be better now, as they are outside the oil, and VAG has gone back to Bosch. You can get individual parts for the Bosch injectors, not so for the dodgey Siemens.

Still I agree we shall see.....

Just as an aside, Siemens owns Bosch and Siemens branded items tend to be higher spec (and priced) - like Audi vs VW

Agreed.

I didn’t know that - do we know if they come from the same facility?

So can we say that they are manufactured by the same parent company (maybe different facility – maybe the same?) But it is still a different part using different technology that fails with a completely different problem.

What did we do before the interweb?

[Greg Roles]

We believed what the dealer tech told us.

Some items would come out of the same factory (the higher end Bosch dishwashers and washing machines come to mind) while others would be made at separate plants.

100% correct in this case.

I’m also not the first person to pay in full… I will update the Failure Register with parts prices, for future reference.

There is also thread for that (when you're out of pocket shortly after the warranty, so you can post there as well.

i think my contribution to this thread is long overdue.

one of the injectors failed back in Jan 2011. SCC replaced 1 (not all 4) at no cost because still under warranty. Three months later, similar incident happened -car lost power and was towed to SCC. I reckoned it was one of the three original injectors. SCC reckoned it was the turbocharger so it was replaced, again at no cost due to warranty. I requested to both SCC and VWA for the 3 injectors be replaced and argued that the turbocharger failure could be due to fuel mismanagement knowing that one of the injectors is different from the rest. After a month long of going back and forth to VWA and SCC, my request was declined. After another 3 months, 2 weeks after the warranty expired, one of the injectors failed again (according to SCC). Lucky i took the extended warranty (backed by Allianz) so SCC and VWA both agreed to replace the rest of the injectors. I reckon VWA agreed as it would be no cost to them, but Allianz.

Pretty disappointing for a 40K car from VW. As a consolation, i've got a 3 year old VW GT TDI with 4 new injectors and new turbocharger. Also lucky to have escaped from all three near-fatal incidents when the injectors and turbocharger failed.

Hey Guys,

Over the weekend my injectors failed again (they failed last december for the first time). Driving down Parramatta road on the right hand lane of the road in busy traffic the car loses power and shuts off. Quick reflex and the hazards go straight on. Cars behind me lose it and beep away. Worse thing was it shut down on a hilly incline around croydon so we couldnt push it out of the way!

Got it towed (via my NRMA) to the dealer and after a few days the guys call me and say all injectors need to be replaced, and that VWA will replace them at no cost.

Happy that the Denlo guys were able to sort this out for me but I am defintely looking at exiting Golf ownership ASAP. It really is a shame as I love my car, and my Mother wanted to grab it off me when I upgraded. With this defect however there is no way I am letting a loved one buy it off me, for fear of physical harm to them. Within the next few months I had planned to upgrade the car and grab a Golf GTI/ or R but these drama's have made me think twice about buying VW again.

Again happy with the Denlo tea, and VWA shouldering the cost of the repairs, its the least they could do right!

Sad to hear you're thinking of giving it up but if I were you i'd stick with it.... as long as vw are paying.
