Hello readers, Looking for advice on changing injectors. On my way up to cheshire from nottingham after 2 hours motoway driving glow plug light flashing then engine light came on, called brakedown service plugged his scanner and gave me the news all four injectors faulty. upon taking the car to my local garage they confirmed i need new injectors £1600 fitted. I have done some research found some recon units siemens 03L103277B £160 each. Hoping I can rise to the challange to fit myself understand units need coding to complete. any advice would be welcome. Cheers

I'm guessing 1.6 TDI?

I find it hard to believe all four injectors have failed at the same time

Also sorry to double post but soaking  where the injectors go with coke softens them up for pulling them out

I do , garage say injectors will not take load test  so need replacing , I have multimeter only resistance of coils around 2k .

I believe @Crasher has a lot of experience in this area.

I agree, EXTREMELY unlikely...........

Assuming it's a 1.6TDI

 

Yeah, one pretty dead and one just going over the edge, I'd believe. 4 seems like a stretch. If I'm giving it a guess without seeing the diagnostic read, I think fuel rail pressure sensor. 

 

I've just had a set of refurb injectors for £250+exchange off German ebay

@diymenber I don't see any indication of the mileage of your car?

 

Also I would hold off on getting new injectors in a hurry to get back on the road, you may wish to pause.

Not to rain on your parade, but you don't generally see 4x injectors go down at one time.

 

This can (IMHO) be caused by some wiring issue, as that could take all 4 down, the next is more scary.

If your fuel pump is starting to break down and metal swarf is entering the injectors, then replacing will cure it for hours/days/??? before it happens again.

 

Please don't take my word as gospel, these are just findings I have seen in the past (brain like a sponge) I am just saying don't rush out and spend loads on injectors without perhaps waiting a little on some further advice.

To be fair it's a known issue with the Siemens injectors on the 1.6 TDI, once one goes the rest tend to follow because the MTBF is what's in play here.

hello VAROOOM, mileage 76k, I paid for a dianostic report at a deisel specialist £72. they have access to electronic equipment ,however I will keep your comments in mind. cheers

Cheers the mileage will help the experts help.

 

As mentioned, don't take my comments as gospel, best of luck with whatever you decide.

My son has a 2012 plate Octavia 1.6 CR TDI and which had covered an almost identical mileage when he broke down on the M6  recently. (Glow Plug light flashing and car juddered to a halt onto the hard shoulder).

Diagnostic checks revealed an electrical issue with Injector No.3.

We took the car to a local diesel specialist who told us he sees injector failures on the VW Audi based 1.6 diesel on a worryingly regular basis and the reason being a sub-standard Siemens Piezo injector. 

His considered advice was that these injectors tend in the main to fail on an age rather than mileage basis, so the fact that my son's car is now coming up to 10 years old is sadly par for the course. His experience was also when one injector starts to fail the others will follow fairly quickly thereafter.

So in the end we had all four injectors changed as well as a new fuel filter. Incredibly expensive for the work done but hopefully some precious peace of mind for a few years to come.

Hope this helps with your deliberations.

The CAYC engine, an absolute joke. The last time I checked Euro Car Part had nearly 9000 new VDO injectors in stock, that is millions of pounds of stock on one item for one engine model, utter crap.

Mean time before failure is only a useful measure of reliability of a device if that device has a 100% duty cycle, injectors are more likely to be measured in mean number of cycles so age isn't necessarily such a good indicator of problems.
