DPF not regenning?

**TheRenegade** · 20-02-2020,08:35 PM

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.

**Artiglio** · 20-02-2020,09:37 PM

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

**Crasher** · 20-02-2020,10:08 PM

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

**TheRenegade** · 20-02-2020,10:14 PM

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

**Crasher** · 20-02-2020,11:57 PM

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

**Whippy53** · 21-02-2020,01:18 AM

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

**TheRenegade** · 21-02-2020,10:33 AM

Yea it was almost full just one LED short of being full.

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.
