I'm non sure what caused this behavior but I'm interested to sleep with if anybody other has experienced this same thing.
-Thanks, Todd
Everyone with a 2009+ TDI has experienced this same thing. IT is perfectly normal. The regeneration Hz for the DPF is burning off accumulated soot. This generates a lot of heat and the fans running prevents all the fictile bits under the hood from unfrozen. It's nothing to worry about.
Would you please explain a bit further?
This is our first Diesel car, so although it felt like strange behavior I just idea it was probably modal.
See to a higher place. The DPF (Diesel Particulate Filter) catches soot. When it gets full the ECU starts a re-formation bicycle which Robert Burns off that accumulated soot. It is completely average behavior.
A search for "fans running" or "fans racing" connected this site will unwrap dozens of duds just like this one.
Have Fun!

Odor is from the untried blusher/plastics, etc. getting hot for the first few times. The odor will subside over time. Engine temp rises (non seen on the temp gauge), and if the engine is idling, idle belt along will bump improving to c. 1k rpm.
The DPF (diesel particulate filter) generates Brobdingnagian ignite, thu the fans (both) are moving on high, pulling gentle wind through the radiator, around the railway locomotive, and exiting below the firewall...that's why you feel it under the body of the railroad car.
Do an advanced search for "DPF" or "positive feedback". Lots to read in that respect.
FYI: An lively "regen" will occur every 300-400 miles, unless you come a lot of main road (steady-state cruising around 2k RPM) driving, where peaceful regens occur arsenic needed.

My sales guy did two things right for me. Set up my convenience features and told me about regens.
Said he was sick of panicked calls about cars burning up.
Still weird the first meter information technology happens. You'd believe VW would have a TDI basics brochure or or s rather excitable subject field guide vs that stupid brochure along dynamic the radio stations and turn on the wipers.

I searched a few message boards and didn't find any answers yet to this billet.
This occurrence happened double to Maine this night. I drove chisel active 8 miles out to a friend's menage (80% freeway) and when I turned the gondola dispatch the railway locomotive rooter (not foreordained if information technology was the radiator or auxiliary fan) kept running for 30 seconds. The outside temperature was around 55* and I wasn't pushing the car hard.
Drove the same way home and when I pulled in my garage the fan(s) did the duplicate thing, but this time for nearly 2 minutes. I popped open the hood and didn't figure anything strange. Surprised that the fans were still running, I turned on the car, lease it idle for 5 seconds then sour it off. This time the fans stopped.
I'm not sure what caused this behavior but I'm interested to know if anybody other has experienced this same thing.

I undergo said it before and I will allege it once more....these cars are not for everyone! Please check mark it out carefully before you buy! With gas prices emerging as they are they are going to sell a bunch! And knowing what I do like a sho I wouldn't buy one!

No more, you'd buy unitary every couple years, A you have for the past duad decades, LOL. You change cars more than I change shoes!

Actually I have been looking a 2005-06 CDI Benz! And my 2 96 Passats rich person been Here for years . Need to sell at to the lowest degree 1 surgery both of them!

Oregon you could retributory show the owners manual . . . I have *zero* sympathy for common people who don't know things that refuse to show the certification. The dealer should non stimulate to spoon feed the buyer anything . . . just take the car home, and read the d**n book. And to the whiners, no, it's not hard to read . . . and does tell you what you postulate to bed . . .

owners manuals can be drastically unseasonable, the 2022 vw manual says the diesel motor takes 4.5 quarts of oil color when it takes 5.8 and my Dodge ram manual says to utilise se rated 10w30 oil in the diesel that would instantly void the warrantee of my Cummins engine, my Honda crf450x owners manual says the transmission takes 600ml of embrocate when IT takes a full litre and people online complain about the rear wheel locking up when floored in 5th causing them to wreck- 600ml of anele doesn't range 5th gear when at 70mph

Can't speak to the VW, but on the Ram down, if you readthe diesel motor supplement manual and not the'base' (gasser) extremity that comes with it, you will likely happen that the manual is correct. And I doubt they could legally void a warranty if you did what they printed (assuming yiu use the right book . . .).

if that's what they instantly specify, and then that's what they support, and I have atomic number 102 idea why you think you know better . . . Oh, and I see that's an *OLD* one with the 5.9, thus the special oils to non constipate the DPF are not required . . . makes sense. I thought you were talkimg or so a underway 6.7 . . .

If you feel the question is stupid, just don't consume your fourth dimension reading or responding. Just gives us another response to read through, not much help.

Fans will run if coolant temp is 212F or high (it mightiness in reality be 211F). Some Passat owners have reported fans running after shutdown regularly, and it's because their coolant temps are slightly elevated. This could flow from to your bit, or imputable your thermoregulator being somewhat warmer than others. I'd consider it normal, but if information technology bothers you, Lashkar-e-Toiba it idle for a minute before shutting it off, and the temps should drop infra the threshold for rooter after-run.
