Engine issues: loss of power, warning lights...

[Thor]

Hi folks! So my van decided to let me down today. 2016 T6 150hp 4motion. I was coming home from work when i noticed loss of power, and then the glow plug lamp started flashing. Managed to get up the hill, parked and turned it off an on again, everything fine for a couple of minutes then the same deal. Third time the same, but check engine light too. Carista reads fault codes P2006, 16399 and 00523.

Anyone able to make sense of this? I tried googeling the codes but this is way beyond me...

Also: Can I limp the van 25-30km to the shop, or should I get a flatbed? I've booked a time at the vw shop online but the first available is next week.

Thanks, google somehow tuned up several less useful threads form here but not that one...

2016 T6 150hp 4motion.

This combination is rare one - could you please share Carista's "Detailed ECU info" (under Service menu)?

This combination is rare one -

The error code combination, or the 2016 150 4motion combination?

Anyways, here is the ecu info:

I took It for a quick 10 minute drive down to the store and back today and it was fine apart for the check engine light. Did not get up to temp thought.

The error code combination, or the 2016 150 4motion combination?

Thank you very much. Initially I was curious about engine software+4Motion combination. And actually you provided a confirmed piece into my puzzle. YouR engine software version is 3803 - which was a kind of expected.

So I'm fairly certain your engine code is CXHA (found on configuration sticker under dash in driver's footwell). Also I'm assuming there is a software update available (latest version 6187).

Anyways, about the faults. Carista has sometimes difficulties to associate faults correctly with control units. E.g. fault 00523 Intake air sensor actually definitely belongs to engine.
Also the fault code 16399 is very strange - no such fault can be found anywhere (=especially very reputable site Ross-Tech Forums doesn't recognize it).

Based on Carista's data the best guess for engine light is the fault 00523 - Intake air temperature sensor - which actually is integral part of air mass meter... (16399?) Any work done around engine air filter?

I see. The 150hp and 4motion is a verry common combo in Norway, iirc something like 80% of t6's sold here have 4motion and the 150 is by far the most common engine. No work done since I bought it in march, 8000km on it in that time. It was about 30 degrees outside when it occured, but it should be able to take that?
