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

[Greg Roles]

The latest from the UK Audi guys:

Also some shocking new detail from an Honest John poster:

You didn't have a new injector fitted at any time if the part numbers you quote are correct.

The suffix "X" on a VAG part number signifies a re-worked old part supplied as a service replacement.

So, same old rubbish re-worked. Nice people to do business with.

The injector 3 that failed again on my car was a refurbished old piece. So when they go around swapping these injectors at full price, they are fitting in someone else's old failure with some parts changed...

Basically the same injector... is there even a new improved one, or is it a myth and we're going in circles?????

[Transporter]

...and on the top of that, the some people with the failed injectors are lazy or just don't want to note their failed injector(s) in this thread http://www.vwwatercooled.org.au/f28/...ter-55060.html

rebuilding injectors is a practice as old as the hills (or as old as diesel injectors anyway). I don't think thats unusual..... they should probably tell you though.

I thought someone said they couldn't be repaired.... clearly they can!

[Greg Roles]

Problem is in the Pizeo part, and they *can* be rebuilt by VAG as they can access Siemens parts, but only VAG have that luxury. There is one place in the UK reconditioning them, but they re-epoxy the pizeo stack, and even they saw there is a failure rate amongst the rebuilt ones. Even though you are putting in new parts, the mode of failure looks like there isn't enough insulation, so the small distances between parts that need insulation remain even when rebuilt. In my thinking all you have done with a reco is buy yourself another 100k max.

They need a redesign, and I'm waiting with baited breath to see what the boys in the UK can get out of VAG with their complaints to their motoring watchdog, and boy do they have numbers over there! The TX version may be a redesign, it's just that VAG is being tightlipped about the issue, and that is my biggest gripe. It's obviously about the money, screw the customer.

[kaanage]

A lot of the blame is probably Siemens rather than VAG (I would think that VAG send them the failed injectors for refurbishing). But VAG should be pressuring them for an ECU update/replacement that doesn't shut down the whole engine when an injector fails.

latest victim (!) - bought a 2008 Passat wagon, 125KW, 47000km's on the clock, bought one month ago from Canberra dealer "National Capital Motors" - non VW) ; so still under dealer statutory 3 month / 5000km warranty. Injectors failed today. Adelaide's VW Dealer "Solitaire" (car flat bedded there) in Adelaide SA immediately called and said Yes they know this site and this thread (!!!) They have done 6 VW's with same issue so far; they will liaise with dealer in Canberra as they should cover under statutory warranty; fingers crossed its that easy....we will see....

[Greg Roles]

Sorry to hear, but glad that at least VW are "aware". The noise about it is only going to increase, a lot of people working together across the globe now. Shame, I love the brand otherwise!

[benough]

Yeah I don't love the brand any less. It's a first gen product, you can expect these things.

MK2 Heater core hoses used to detach under pressure and fill the passenger foot well with hot coolant. I imagine in 1992 that would have made you furious that your $30k hatch had such a defect.

That said I still love driving the MK2, even after having to remove the dash

[Greg Roles]

I'd take a water burn to the foot over a truck rear ender at 100kph... just got this sent to me.......

This is my ENTIRE gripe, it isn't a leaking sunroof or rattles in the dash, it's going to get someone hurt.

[poyta]

Yeah that is scary - I wonder how sudden the engine shutdown and a stop is, I wonder If I'd have enough time to put the clutch in and just coast slowly to the side if that ever happened.
