View Full Version : DPF not regenning?

Hi guys,

I've been having some issues with the dreaded DPF.

I have a 2014 A6 Avant 2.0 TDI Ultra. I do lots of motorway miles so I'm assuming that the DPF will do it's regens while I am driving. I've never had issues since I bought the car until about 6 month ago when the DPF light came on. I didn't think any thing of it and took it out on the motorway. Sure enough the light went out and I was happy. The problem never occurred again until Christmas. The DPF light comes on at least once a week, sometimes, mid journey. Then when I take it out on the motorway (normally while I am out for work) the car will start flashing coil light, engine light comes on and the car goes into limp mode.

I have a VCDS cable and scanned the car. I have also tried to do a forced regen on the car. The strange thing is that when I do a forced regen, it always stops at 300 seconds and doesn't go any further.

Below is a full scan and other information. Any help would be much appreciated.

I wonder if the fuel cap fault is stopping the regen.
Wil that fault clear ?

I don't think so because it's just saying that the tank cap cannot be locked when the car is locked. It's another thing on my 'to-do' list.

I’ve a facelift of same car, i do a fairly regular 300 mile run, not unusual for it to do a regen the day after if i’ve driven gently , to get round it i usually do the last 50 miles in manual ,hold it down a gear and be a bit more enthusiastic. That way i rarely get a regen in day to day driving. Car has 72k miles

VCDS is often problematic initiating a forced regen, did you enter the login first?

Yea I did it via security access, before doing anything else. It just never completes the regen :zx11:

Yes I get this a lot, is the fuel tank more than 1/4 full when doing this?

Do I read 156k? Possibly due a new dpf.

Yea it’s done a lot of miles. But I wouldn’t even know where to look for a new DPF. Im not going to buy one from eBay without knowing it’s history properly.

I suspect it's an Audi job.

Get it cleaned, DPF Clean Team Hinkley, on your doorstep. Excellent people.

I think I probably will go down the cleaning route. I know for a fact if I go to Audi they will want me to remortgage my house and sell a leg.

I’m just confused as to why the regen never completes.

As an update...I had a 160 mile round trip for work yesterday. I first cleared the errors and then tried another forced regen before heading out. The regen stopped again after 300 seconds. While I was out I tried to keep the revs high (2500+). It took about 70 miles for the DPF light to go out. No errors on the way back and the start-stop function was working again.

It sounds to me like you need to give it an Italian tune up every now and then, driving economical all the time, keeping the revs low and exhaust pressure and temps low doesn't do anything any good. Booting it up a long steep hill keeping revs high (2k +) as you change gear should greatly increase exhaust pressure and temperature as everything works harder than normal driving, it should help clear it out so to speak.

Possibly ash loading, when it's full it's full. Official service life is I think something like 120k. Do we know if the vehicle has had 'the fix' applied?

Are you using proper fuel too? As in Shell? Cheaper fuels can burn less cleanly.

There you go then, a tankfull of Shell, a rant around the local housing estate and Bobs your uncle. No need to even get the spanners out.

Always used Shell or BP.

If you mean the emissions fix, then my car doesn't qualify for it unfortunately.

Good, because it kills dpf's. My guess is it's full of ash and as crasher suggests, get it cleaned.

I guess that's the best route to take. I'm trying to sort something out now. I'll report back what happens.

Why unfortunately, the recall screws them up.
