Do some searches... some experience failures, others don't.... some claim (@volkswagens-for-life ) that dealer sourced DEF is the secret.... just be glad that you still have lots of warranty left and this isn't happening on your dime.... start thinking about deletes since it appears that you have a lemon.

 

I feel for you. Most of the issues with these cars are related to the emissions systems. I had a heater go bad under warranty,but knock on wood that was The only issue so fAR. mY 2016 ONLY HAS 25,000 MILES , bgt after the scandal as a new car in 2018.

 

Yes, it becomes clear that I do have a lemon. My warranty runs out at the end of next year or 120,000 miles but the end of next year comes first.
So I have a good year to figure out how my next car is going to look.

I can't find my calculator to check my math, but in my head, a 2015 + 10 years is more than 2023.... also looking for my calendar to check the date!

 

So they replaced all those parts and didn't look at all at the AdBlue injector?

What codes were stored?? You will get NOx sensor codes if the injector is faulty but they are likely a byproduct of the actual issue.

Time for a new dealer I think....

The service guy this time was talking about the injector.
Can’twait to find out what they have done or fixed this time when I pick up my car.
I’m also starting to believe that there are few good diesel mechanics out there.
The first thing this dealer did was calling the VW help line and another dealer told me that it was very tricky to work on the computer with these cars.
We’ll see.

 

This exact thing has happened our our '15 TDI. Only used VW DEF ever in the vehicle. The low on ADBLUE message comes on, I fill it up, then the ADBLUE message goes away, then randomly within a day the "you're almost empty your vehicle will no longer start in 80miles" message comes on - no yellow check engine light ever. Dealer could not find it, but if I just do a scan of all codes/faults with VCDS and then clear all codes, it goes away and is fine until the next time the tank gets low. Dealer thinks it's a computer glitch with the float level interface measuring the level inside the tank. I'm not pushing fixing it because not sure how easy to track down and what else might get messed up if they just start changing parts out willy/nilly. VSCS is your savior!

 

Your dealer is a clown because there's no float.
Start using a different dealer as when something fails, they will screw up your TDI.

 

At almost 200,000 and running like brand new the day I got it I'd say they've taken extremely good care of my TDI even if they are clowns. Maybe my misinterpretation of language, but the results with clearing codes with VCDS works just fine.

 

Interesting that you'd also say that you don't know what else they would muck up while throwing parts at it above......
Seems like a contradiction to me, but as long as you're happy, that's all that matters.

 

I've had that happen 4-5 times over the years following the dieselgate 'fix'. Both NOx sensors have failed/been replaced, one has been twice. The AdBlue injector has failed/been replaced. And most recently, it was crystalline buildup that got into the tank (dried urea solution) and clogged the AdBlue injector - which initially made the tech think bad sensor. Diagnostics showed good sensor, so they looked further. All a nuisance, especially when you have no advance warning prior to that "SERVICE NOW OR I WON'T START!!" message, and you're farther from any qualified dealer/private shop than the miles remaining. A good shop will understand the codes the car is reporting and will diagnose logically. I don't use VW AdBlue, so they always check the quality of the fluid to assure that's not the problem - and it always passes - and I've used at least a half dozen different suppliers of the fluid. Crystalline buildup - if you use a VW AdBlue bottle later as a funnel for the aftermarket stuff (e.g. cut the bottom of it off; the press to dispense is pretty handy, esp when you otherwise can overfill the tank), be sure to rinse it with clean water after use. I do now...

 

I suspect that many dealers don't fill the tank up to the top when they change the oil and do the expected Ad blue fill. It happened to me in the middle of a trip with only 5,000 miles from the last fill up. It usually doesn't set off a count down when I have my oil changed at close to 10K miles.You have to be pro active.

 

Have the code cleared numerous times in sequence. My 2015 had this issue and the indy shop guy kept clearing it until it stopped. Got the message 6 times? Clear it 6 times. I have no data other than to say it worked for my car.

 

Will tell the shop, thank you for letting me know.
