Volkswagen 1.6TDI Engine Injector Failure!

Volkswagen 1.6TDI and 1.9TDI engines are known to sometimes have faulty injectors that can be a costly fix! In this video I will tell you how to identify which injectors you have and how to save money on costly repair bills!
The 3L130277B injector type has gained notoriety due to a known issue with its piezoelectric actuator - the small capsule located on top where the electrical connector is situated. This tiny yet critical component can spell trouble for Volkswagen owners, causing performance issues and potential headaches.
The Problem: Piezoelectric Actuator Troubles
The stack of piezoelectric crystals within the actuator tends to crack or break over time. This degradation leads to a significant drop in electrical resistance, plummeting from the standard 180-210 kiloohms to a mere 5 kohms or less. An open circuit is also a clear indicator of actuator failure. While electrical resistance isn't the primary function of the actuator, measuring it becomes a reliable method to determine if the crystal stack is mechanically compromised.
Why It Matters: Performance and Costly Repairs
A malfunctioning piezoelectric actuator can result in a cascade of issues, including rough idling, misfires, and decreased fuel efficiency. Ignoring these symptoms may lead to more severe engine problems over time.
Moreover, the cost of injector repairs can be a significant burden on your wallet. But fear not, as we're here to guide you on identifying these problematic injectors and how to potentially save money on those looming repair bills.
Using high quality fuel can reduce the likelihood of deposits accumulating in the injectors, promoting better engine performance.

Servicing your van is a good thing, but will have no impact on when or if the injector will fail. Also injector cleaner will not prevent it either. The point of failure is the electrical switch part on top of the unit, not the main body of the injector. Hope this helps.

[@willsvanadventures]

That's good to know! Do you know if they have sorted this issue with new models? Thanks!

[@falconzg]

2012 1.6 TDI 215000 miles no issues with injectors I always use injector cleaner two treatments once a year, always change all of your filters and quality oil, people usually don't maintain their cars properly

[@willsvanadventures]

That's insane! Thanks for the tips! I couldn't agree more! So many people don't bother to get cars serviced regularly.

Hello. Mine is a 2012 Seat Leon with the CAYC engine and 113K with part service history. It developed a misfire last summer but it was intermittent. Sometimes it didn't misfire from cold up to normal running temp. Sometimes it would only misfire at cold idle. It always seems to run fine above idle, say 1500rpm and cruises on the motorway fine and performance is unaffected although 50mpg at best on a run and 38mpg locally which seems low. It was tested by an injection specialist last summer who found injector 3 was delivering more fuel than it should and injector 2 was compensating with slightly less. I have just today checked the resistance and all four are 202kOhm which I didn't expect. There are no related fault codes. The exhaust smells of diesel and is damp with diesel around the exit. It recently developed a loud ticking which sounds like a dud hydraulic tappet only on one cylinder - I've changed the oil just in case but the oil seemed fine and doesn't smell of diesel and the level has not changed since I changed it 3000miles ago. 2000 miles since the misfire started. It always starts easily cold or hot. It is smooth until the stationary idle drops to 800rpm at which point the misfire takes a few seconds to make itself felt. If this is a leaking or weeping injector what could be the possible fixes please?

[@willsvanadventures]

I wouldn't know I'm afraid, best to talk to a mechanic! Sorry!

[@deekayunited3445]

My 2011/85k Caddy Maxi is getting the EGR replaced tomorrow (ouch). It's had injector 1 &3 replaced already (one of them by me). Limp mode when the EGR is faulty is tolerable. Limp mode with an injector gone is undrivable. So I'm toying with biting the bullet and just replacing the other 2 injectors. The vans not long been MoT'd and it's had quite a bit of work done on it in its former life (BG van), including a new turbo @ 61k, a suspension overhaul @ 73k and a brakes & Master cylinder overhaul @ 75k....so I think its worth it. Maybe :-)

[@willsvanadventures]

Damm sorry to hear! I wouldn't fix it until it's broke personally, especially if you get breakdown cover from the AA then they'll cover the majority of the bill. Let me know how you get on!

[@rejoicerone3176]

Hi, i have a 2017 Golf MK7.5 so it has the new Delphi Injector, are these problematic? On 86k now and no problems so far - ran on premium diesel and occasional Redex diesel cleaner added on every month

[@willsvanadventures]

I'm not sure sorry, I don't think it will be. I would just leave it and continue as you are. Don't need to fix anything unless it's broken so you should be completely fine!

[@kthompson4622]

Hi mate Is this injector problem with the 1.6 only or does the 2.0 model have the same issues also ?

[@willsvanadventures]

I believe it's mainly the 1.6 but could be the 2.0. If you check the tops of the injectors for the codes, you'll see which ones you have.

[@draganku]

I find leaking injector 4 ..on top..like 10/15 ml..per month..vlean it and again..but the car drives ok..1.6tdi vw .. Advice? Pls

[@willsvanadventures]

I don't know sorry, have you found a solution?

[@ohyeh845]

Mine just went on AP68 in Spain, having all 4 done 3000€, 4 extra nights in hotel , paid by insurance

[@willsvanadventures]

That's annoying but great to hear the insurance is covering everything!

[@Hoppa12345]

Its not carbon builds up. Its water moisture building up on top of the injector. Ive tested the fuel on top of the injectors from different cars which failed. all of them contained a high amount of moisture .

[@willsvanadventures]

I didn't know that, thanks for sharing!

[@Matthew-hs1qi]

Thanks 👍 how much you paying for the parts and garage cover?

[@willsvanadventures]

For the year it's about £200. Depends on make and model etc. I've used it a few times so has been with it. Had all my glow plugs replaced and only cost the £35 excess.

[@Matthew-hs1qi]

@willsvanadventures thanks is there any small print I need to look out for? Think I'll look into it in next year

@@willsvanadventures yes buddy I had a 1.6 caddy for 5 years I Had a injector go at 28k miles and 2 go at 40k the fuel filter was full of metal specs from the pump mad at that millage I know have a 2.0tdi one both great vans to be fair mate

[@andyallenby900]

If you replace all the injectors will they still be problematic?

[@willsvanadventures]

No they shouldn't be, they might not be a problem to start with. I wouldn't fix something unless it's broken tbh.

[@andyallenby900]

@@willsvanadventures I’m off to view a 1.6 that’s had all injectors replaced, but been told to stay clear because of the problem. But if the problem was with the original Siemens injectors surely with them being changed the problem won’t be there anymore

[@willsvanadventures]

@@andyallenby900 yeah exactly it should be fine! Loads of people don't have any issues at tall. They are good engines and will do 200-300k miles unlike most other brands. If you look after the van, service it regularly every year or 7k-10k miles you should be fine. And get AA breakdown cover incase anything goes wrong and they'll cover most the bill.

[@crazycurtis28]

Where the heck are you getting your parts from? Even now they can be found for 250 each. 400+ is mad

[@willsvanadventures]

Parts might be that cheap but the cost to get them replaced is much higher. Especially if they get stuck or it's on the roadside, that is the going cost. AA on the roadside repair is now £700 per injector.

[@mrcneale]

@@willsvanadventures I can attest to this, painfully. Had one go on my 1.6 TDI bluemotion hatchback on the way from London. £700 from AA. 70 miles later, 2nd one went. Yep another £700. On eurocar parts the siemens injectos are still almost £700, the Lucas ones are nearly £400 Looking into the AA parts & garage now thanks. (I only had AA via my bank and 10 mile recovery...long story about why I went so far in our old car) @crazycurtis28 where can you get them for 250 from?

[@Smash-n-Grab]

Knockoffs from ebay more than likely lol

[@cg3205]

@@willsvanadventures Even more. AA came out yesterday and quoted me £800+ to put in a new injector at the roadside.

just had this happened to me after 115k miles and 14 years, bought some used updated S injectors and solved it

[@willsvanadventures]

Ah man that's annoying! Good run from the van though and glad you got it sorted!

[@Gabasto]

400-700 for a injector? is it better to get a used injector?

[@willsvanadventures]

Yeah it is with fitting, I'm not sure but I'd like to think a new one is better. Or get AA parts and garage cover.
