Sorry about that. I read this thread back in December and forgot about the formatting. I will update more once I am able to gather more information.
Well been 14 days in dealership so far. New turbo came in from Germany and they replaced oil pump also. Noticed lots of oil in exhaust and into catalytic converter so they have now ordered one and should be here Monday. He is also figuring will need some sensors as will be oil fouled.Yea I don't pay them for oil changes. This will be free or nothing. Will try to get ahold of VW Canada next week.
Has the 23N5 update actually been tweaked since its release, or the "revision" simply CARB's approval for the same, unchanged update?So a little update I just noticed (CA is no longer excluded);

Updated with P/N's and new failure of the NOX Sensor.Norther NY State. Turbo blew the 2nd week of December.
Avg start up temp teens or low 20's in December.
2013 Passat SE TDI 8,000 miles.
Exited the highway and noticed a small turbo whine. About 1 mile later turbo noise was very loud and heavy black smoke with flashing alerts on dash. Took 8 days for the dealer to get the parts but I had a loaner passat. TSB was followed and all is OK so far and we have had average start temps for January at about zero or colder. Lowest was -32.
My dealer mentioned that the warranty for the turbo system and emissions system was extended to 100K miles. Should they provide this in writing to me or is there a memo somewhere I could keep with my files?
Miles on car at failure: 8,000
Corrective actions from dealership: Followed TSB
Outside air temps at failure: 10 degrees
Failure warning signs, if any:Not sure if it is related to the failure or cold but I did have to top up coolant. Loss of power and turbo whine. Followed by heavy black smoke from exhaust.
Warning lights on dash/MFI: Once the heavy black smoke appeared, flashing ecm warning lights.
Problems since replacement:
Repair time: 12 days
Any dealer divulged info on other incidents involving other failures:Around 20 other failures.
Did the dealership perform all maintenance and on schedule: Yes.
If not dealership, what oil was used/miles on oil:
Are you the original owner of the car: No. 2nd owner.
Did you baby your car or not:Yes. Previous owner also adult driven.
Do you interrupt DPF regenerations: Unsure.
How long is your daily commute: 16 miles each way.
Transmission (DSG/auto or manual): DSG
Failed turbo part number (if known):
Replacement turbo part number (if known): 03L253056QX EXMAN TURBO
Did you have the Jan 2015 23N5 software update: Yes Completed at the time of repair.
Update: Check engine light on 1/28/15. Fault code for NOX SENSOR B1S1. Replaced sensor P/N: 03L907807AD. Dealership stated that they believe it is from the turbo failure as well and are reporting it to VW.
Received the following message on my Turbo Failure Facebook page today:
"Jay Shurtleff: Turbo failed today. 5 days after the software update. I had no problems prior to the update."
First turbo failure after software update that I have heard of.
I don't believe the CBEA and CJAA have the warm-up routine our CKRA's do. I suspect this is because they, unlike our Passats, don't utilize SCR, which requires heat to turn urea into ammonia in the exhaust stream. If the exhaust stream and SCR catalyst are relatively cold, the process of reducing NOx is ineffective.I realize the Golf and Jetta TDI's have a slightly bigger turbo than the Passat, but surely they go through the same warmup process that our Passats do, correct? Have there been ANY reports of failures on those vehicles? If not, why/how are our turbos the only ones experiencing this problem?
OK day one after VW computer flash update these are some points I noted. If someone has or wants to make a list of points to note during regular start and drive, I'll note those in the future.
Ambient temp: 55
High EGT1 Temp: 1125+-
My typical drive in the am cold is level, no hard acceleration for about 3 miles on 45mph or less side roads prior to the hwy. I let car warm for 2-3 or more min typically before getting on the road, this am was 2 min for the test.
No noticeable difference in engine response.
Highest egt1 temp on drive was under 1300.
They do not. The warm-up is for the SCR systems that the Golfs, Jettas, Beetles, and A3s do not have. That said, all 2015+ TDIs should do the warm-up, but I haven't driven one with a ScanGauge and cannot confirm one way or the other.I realize the Golf and Jetta TDI's have a slightly bigger turbo than the Passat, but surely they go through the same warmup process that our Passats do, correct?

Happy for you. Maybe post this in the Flash discussion?Got the flash update today and have no worries or concerns about it. In and out in about an hour WITHOUT an appointment and they even threw in a free car wash.
This was at the new dealer in town.
VW of Lees Summit (Missouri)
They have other VW dealerships in Utah and Florida, but I don't know the names or locations.
It wouldn't surprise me *at all* if VW was blowing up new BV39s with the warm-up routine just like they blew up BV40s. Let your engines warm up for two minutes before driving, people!
