Just an update on my issue: I got a call from the customer care rep and he indicated that they will be replacing the heater core on my vehicle free of charge as a "goodwill gesture". Will update again after I get a chance to get the work done.

I am driving my bosses vehicle now as my cabin smelled of coolant and I didn't want to continue driving it with the unaddressed issue.

Good news on the "goodwill gesture" wonder if others will be as lucky.

A little coolant in the cabin never hurt anyone

Also the NMS Passats had issues with clogged heater cores.

I personally think the operating temps the coolant sees possibly due to the EGR is too high and is breaking down and that's the "rust" you see in systems, but thats just my hunch.

Got the car back today, CEL gone, no cost to me. VW dealer was very pleasant to deal with through the ordeal.

Driving today was the normal post-emissions experience. I'm putting a few hundred miles on over the next few days, hopefully no more issues to report. Thanks for the help.

Sounds like N2UADTDI should call up VW Customer Care

Add me to the post fix P2457 problem. I did notice the heater core last winter was not putting out heat like it did when new. Had a local mechanic do a backflush and a ton of gunk came out which gave me marginally more heat.
Car has 160,000 miles on it, fix was done less than 5,000 miles ago.
I have never had any issues with this car before the fix, but since the fix I have had 3 separate check engine lights come on.
1.) po472 exhaust pressure sensor. Replaced myself, the one behind the oil fill cap.
2.) p2015 Intake manifold flap. Bought the dieselgeek mod for this
3.) P2457 EGR fault. Debating on having dealer fix heater core or take to local shop and see if that clears out.

I am leaning on working over Volkswagen since the previous OBD programming did not detect this fault, and now I see plenty of others are getting this post fix.

if you had the fix, I would take it to the dealer and let them fix it all under the warranty.

any extended warranty only applies after you have declined the buy back, and had the fix completed.

if you have done neither, you would be responsible for repair of any defect which causes an MIL before the fix, or could sell back as long as it drives into the dealer under its own power.

The dealer won't even attempt to start the emission fix until all CEL are off, and that will be your responsibility to get that repaired. That's what I was told.

I have a manual 2013 (no fix yet), and got the P2457 after the dealer had to replace the A/C condenser.

What is VERY odd is since they replaced the A/C condenser, my electric fan run for about 30 seconds after the car shuts off. It didn't do this before they had the car.

Does anyone else have their electric fan run after they shut off the car?

Odd, I had the fix done 9/17 and the AC failed 10/3. Fixed the AC, new compressor etc. 10/10 and got the P2457 code today 10/12.I have the 2014 Jetta TDI.

To replace the condensor/compressor they may have to disconnect some coolant hoses and place the front clip in the "service" position. If that's the case, maybe the drain refill, stirred up enough gunk to clog the core.

Big thing is this was noted on two different platforms/engines. Passat has the W2A IC and the Jetta has the A2A.

Also the Passat is known to run coolant high 225-235 and has a slew of known issues with "bad heater cores". I believe, the fans will always run if coolant is higher than 220. I'd wager the 2012 we had bought back had a fair amount of "gunk" in the coolant system as I noticed the fans on way more often than regens.

Just a guess

I think mine is just unrelated, it was cold the other day and I have no heat. Looks like it's a plugged heater core and 740GLE is spot-on.

Update: Did some digging and the heater core is covered by a warranty extension (thanks TDI club!!). Called the dealer and they confirmed. Car is currently at the dealer, repair will be covered 100% by VW.

Enjoy the heat, you probably had a failing heater core last winter. Guess the benefits of the extended warranties are starting to shine. If i were anyone's shoes close to deciding about getting the fix, I'd do it ASAP to start the warranty clock (09 DSG bricked ones outstanding).
