DPF Clogged
Hi all, I am the very proud owner of a 2014 A8L 3.0 TDI. I absolutely love this car, and feel the engine was a perfect compliment to it, it is a crying shame they can't/don't offer this option any longer.
Today I was moving my car from one building to another on the same campus and got a message saying there was an issue with my DPF, then a CEL along with the glow plug light flashing. I scanned it with OBDeleven, and it mentioned three faults (sorry I forgot to get the actual codes) one was for a overloaded DPF, another for a Nox sensor issue, then a third related to the DPF (I forget now). Anyway, I also experienced reduced (a lot!!) power while driving. Needless to say I took it straight to the dealer who is going to investigate the issue.
I was wondering if anyone else has had an issue with similar in this engine? It also got me thinking how easy it is to pull the DPF out permanently (once the extended TDI warranty expires of course!) to prevent this issue possibly occurring in the future?
I will update here with what they find, I am hoping it is just a simple DPF clean, and I can get my car back! ☺
Edit: I also notice a rattle one start up sometimes, like the timing chain tensioners need to activate? It only lasts a couple of seconds, and doesn't happen at every start up, I was wondering if this is also normal for this car? I mentioned it to the dealer to look into while they have the car anyway...

I have still to hear anything back from the dealership about what they have found. I am sure they will reach out soon enough. I am more than happy to put miles on the little loaner SUV (Q5) than my car for a few days while they fix it. I figured if they were trying to push blame or worn their way out of covering it, I would have heard something pretty quick?

So I wanted to post an update to my post. Apologies for the long gap, I have just been busier than a one armed paper hanger here of late..
They had my car for a few days, then called to say that they could find nothing wrong. The check engine light cleared itself (although the codes were still there when they checked) the SA tried to tell me it went into a regen, to which I replied I seriously doubt it did say there in the parking lot not running. Regardless, driven the car a few weeks now, no further issue, and like the SA mentioned, I have the 10/120 warranty for a good while yet, if anything were to rear up again in the future.
I hate leaving threads out there hanging. For now I will leave it at this, but will update this if anything changes in the future!
Oh and zero cost for anything they did as far as testing and troubleshooting, a pleasant dealer experience all round!

Awesome information! Thank you for sharing! Hopefully it doesn't come to that, but good to know we have protections in place if it does start becoming an ongoing issue ☺
