Piezo Injector Failure, and subsequent detection and repair.

Im not sure why this shouldnt turn into a "who should pay thread"

If the part was £50, then i wouldnt be so bothered. But to get a £1000 bill for a car just out of warranty should, should be unexpected.

Injectors for other brands are £40. As consumers were stuck as there is only one source for audis very expensive part.

It seems a relatively common problem. How common does it have to be before audi accept its an issue that should always be covered by them, whether in warranty or not?

My car is in at the dealers. The bill is over £1000. They are an empowered centre i.e. they have delegated authority to make their own goodwill decisions and are completely unwilling to offer me any goodwill. I've been trying and trying on the phone and even highlighted the fact that this is the second injector to go in 2 months and they're not interested at all. I am absolutely disgusted at their arrogance. Even Audi UK customer care have offered to match any goodwill the dealer is willing to give but the dealer's not having any of it!!!! I'm going to tow my car out of there and take it elsewhere, they are never getting my custom.

Second injector has now been replaced. I have now had 2 injectors fitted in the last 2 months at a cost of about £1400.....what should my expectation be now? Does anyone know if the remaining injectors a very likely to follow suit and fail?

Zaz. Is yours a 140TDi as the prices you quote for parts are actually a lot lower than they could be. My quote for 170TDi injectors were almost double - see earlier in this thread. If it is 140, I was not aware those injectors had the same reputation for failure. If 170, you have very good prices, believe it or not.

Hope you're all sorted now.

Sorry folks, prices I had seen were not yours, zaz. They were Craggit's prices. Maybe he has a 140.

Guys mine is a 170 and I actually got the repairs carried out by a non-franchise garage as the Audi dealership couldn't care less about the problem.

a8 tech, I wonder if you could tell me, are the new injectors any more reliable than the failed ones in the long term i.e. are they technically different or is the piezo element problem solved? Thanks.

Zaz - take a look at my reply on 6 Feb in this thread. I found a reference to upgraded injectors on later models.

Just a quick one guys...I've just had mine diagnosed as being a faulty injector (lucky me i know!!) i have an A3 2.0TDI Q 170...BUT....i have just put some redex in the tank and find it a little coincidental that an injector fault has appeared, any chance that the fault could just be a blockage?? i have heard that these can be cleaned in a sonic bath if that is the case....obviously I'm hoping because a £750 repair bill is not what i hope to pay!!

[patrickhorton]

The fault the thread is generally referring to is an electrical failure in the injector. So no kind of cleaning will fix that. Maybe you have some other problem though.

As a general note, there are used injectors for the 170TDi like I bought still on ebay for about £200. May be worth paying someone to fit or DIY. I'm sure it would work in the short term - can speak for reliability long term.

Good luck.
