Has anyone had their front flexi on their exhaust replaced? My DPF is good but the flexi is going as seems to have pin holes forming can a new one be welded in or can it be sleeved?

Just to add to this - it really p's me off that the engines most fuel efficient speed is bad for the DPF - I did a run to Cornwall and back and got 43mpg by sitting at 60mph on a return trip of 600 miles All was good but then after refuelling I got the dpf light on, that went after a blast up...

Make sure it's DPF compatible. Usually says so on the label.

Adblue is definitely pre-DPF, not post.

Interesting you mention 15%... The T6 ECU smooths out the extra bit of fuel in the DPF regeneration in the following (typically) 60-120 km by showing 15% worse MPG on MFD. Showing the real MPG during the DPG regeneration would be... . unconfortable... thus VW alleviates the anxiety by spreading...

Please post "Detailed ECU info"-report (under Carista Service menu). Soot level 60 g inhibits DPF regeneration - the DPF needs to be replaced (or cleaned). Also ECU defnitely should report that as fault. Was there any mention about engine remap? Is the tailpipe sooty...

Thanks for the fast response guys, yes understood, it’s the DpF that worries me.. I would try and give it a blast now and again but my Dad tried the same and still ended up in the dealers 3 or for times before he gave up with it.. Did I read there is a T6 without Adblue / Dpf - like a...

Hey mate. Strongly suspect a fully blocked DPF so it’s back at the dealer now for investigation and possible DPF clean / replacement. Still not sure if this is the result of some other, underlying issue…. Or just the DPF reaching the end of its life and no longer able to regen. Will report...

That's exactly what I had done a couple of years ago. Done maybe 20k miles since. DPF regens are currently about 150 miles local driving and 225 on a long run.

Sorry to hear your tail of woes I have a 204 CXEB with the DPF off at the minute, the measures ash level was 76g. Once I eventually go it off the van, I run a hose pipe into it, filled it up completely with water with only a trickle coming out the other end, an overnight soak in Wynn's DPF...

Thanks again for your time! So as I understand… I may be wrong… EGR is good, DPF, is good, turbo actuators are all good… So we’re looking at the remap as the possible problem as it’s asking for too much boost?

If you are on Android there is VAG DPF (which I use) or on iPhone DPF Monitor Long thread here of some suggestions and comments: https://www.t6forum.com/threads/best-dpf-monitoring-app.23342/ One thing to note is that as the DPF is cleared by increased heat counterintuitively if you work the...

Why not just wait and see what happens with the DPF and if/when it starts playing up, weigh up your options then?

ahh for Android there is another, sorry I cant remember. There is a thread here somewhere with info. Search DPF app

Dpf regen run by engie ECU. Uses throttle body to control air inlet and turbo and EGR to adjust airflow. And injection timing to add fuel to outgoing exhaust. All combined to increae dpf temp. Various pressure and temp sensors used.

There’s a calculated ash value in the ECU for the DPF. It has a limit set, I forget what it is, but when it reaches it, it’s dpf replacement time. I’m sure there are other values also measured that trigger it too. 30k seems low, but my neighbour had a 110 he used to deliver Amazon parcels, lots...

I had the same concern but was assured by the tuner it would regen as before. I believe this is because adblue injection is post dpf? I’ve been monitoring it on the dpf app, though the frequency is less than desirable when it does regen, the soot mass does drop to the required value.

...km to 238763 km = 184 km, 2 hours. Plotted the two soot mass parameters (calculated & measured) which are used by ECU to monitor and trigger DPF regeneration. Normally "soot calculated" (blue) is the dominant one. Here it's a kind of opposite. As soon as "soot measured" reaches the DPF...

Hmmm.... but the DPF and EGR were deleted? Catalytic converter still in place? I guess the smell is only engine idling (would be difficult to sniff otherwise?)
