I don't know that I have noticed rough/higher idle at a light, but will start to look for that. I have definitely noticed the high-speed fan running for minutes after shutting down. I wondered what that was; it would make sense that it was regens -- I wondered when my car would be doing that. I think I noticed the smell, and wondered what that was too.Find someone to check your DPF for soot and ash load. Sounds like your car is using too much fuel in regens. Do you ever notice a rough idle at slightly higher RPM when sitting at a light? Or having the fans run at higher speed after shutting down? Also the burning rubber/rotten egg smell from under the hood. All of these are indications that your cars is doing a regen. Unless all of your miles are highway, you should have noticed at least one of these.
Thanks. I do have a friend around here with one of those, and I'll see about that soon.I have the VCDS but no working windows laptop, so can't really help you from Charlotte.
So, I've been hearing this about the tdi's regen cycle and short distancesA long ways back someone here pointed out that tdi's weren't for sale on some small island(s) due to this. It would be difficult to actually drive there enough to accomplish the regens when needed, without taking special actions to let them happen. At 5 miles you should have been considering an all electric car. They shine for that kind of driving. You do seem to have picked the wrong tool for the job though.
From my experience, the regens usually start when I pull into the garage or parking space at work. I could have just completed a 400 mile day and it still seems to want to start an active regen just as I'm shutting it down. I know, it's all timing and this would not have been the first one of the day. If I notice it starting at a light or slower traffic, I'll kick the tranny over to manual and keep the rpms higher for a few extra miles.So, I've been hearing this about the tdi's regen cycle and short distances
..... is there any magic number of say non-stop driving miles one should drive daily for this not to be an issue..
I see this is a loaded question because of all the variables. I drive daily 2miles back roads, 13 miles highway (65 mph) and half a mile to the parking garage. Followed by the same routine in reverse back home. Is this trip sufficient for the health of the tdi's?

So true. And so annoying. If I catch it I'll let the car idle for a few minutes, unless I can't because of time or location. I keep telling myself that VW designed the system to accommodate these driving and stopping conditions and it should be fine, but it still bugs me.From my experience, the regens usually start when I pull into the garage or parking space at work.

No it also tells you where it is at at any given moment as far as how close it is to doing a regen. You can easily tell if it has just regen'd or one is looming really soon or is in progress and about how far along it is. Ash buildup. All usefull info.Yes, but...all it really does is confirm you're in regen. You still have to decide whether to ignore it or keep driving 'till it's done. Irritating. That's one of the reasons why I use my older TDIs for local driving.
It's a sort of sickness and you are probably better off without it. Been a gear head all my life, can't stop, I want to know all I can about my ridesGuess I'm a bit of a luddite about this stuff. I just want to drive the damn car. I don't like the FE readout, either. I prefer not to think about it until I refill. How I'm doing based on gauge position and trip mileage is enough info for me.
