I've been deleted since 30000 and mine was completely clogged at 70000. I think the damage was already done though. I went 2 winters with very poor heat so I was probably closer to 30000 when it was happening. Ive gone to green organic acid coolant and installed a coolant filter and Im issue free at 95000

When I pull mine I plan to plumb in an inline filter.
Link please?
I found some kinda might work ideas on amazon. Obviously with a delete there's gobs of room for plumbing and elbows to get something in there easier.

I think it's a mistake to assume that the heat of the emissions systems (EGR, DPF regen, etc.) is causing this coolant problem. At this point that's a theory and very anecdotal, not proven. It's much more likely to be a chemical mismatch of some kind putting the coolant into a pH level that is too high (acid), with bad results. Without going back and reviewing this thread again, it seems to me to be the case that some people are getting this covered by VW outside of warranty, and some aren't (in typical VW fashion). Who has definitely gotten coverage from VW (NOT dealer!) outside the 3/36 B-to-B warranty?

I was only able to find one very pricey option for a true inline full flow filter. They bypass types are much cheaper and there are more options. This one was from dfuser diesel on eBay. I modified the bracket and mounted it in front of the transmission to the frame rail structure. I T'd into my frost heater line and ran a return T'd into a return for the reservoir. The system is working very well and I haven't had any debris in the reservoir since install. I cut apart the first filter and it wasnt plugged or anything but it definitely caught debris
Damn. Hoping you also had links/photo/directions of heater core removal.
Ive been reading the dash doesn't need to be killed. Kick panel and console?
If i do delete and get into the heater core and oil cooler, should I dump the pink and go old school green?

Since there are pix showing how to get at the heater core for the NMS Passat (the subject of this part of the forum), I'm assuming that's not what you have?

How to and more reading on pink vs green here
Per info under user 'jason_' name he has a "broke ass 2009 wagon" (that's what he put down) - doesn't say if it's a VW or even a TDI. The Passat was not offered with a TDI in 2009 so I assume he has a Jetta Sportwagen.

Just to clarify, too much acid would give a LOW pH value, not high.

I just received a letter telling me this is now covered under and extended warranty item to 10 years or 120,000 miles.
Gee, I wonder if they'll reimburse the hours I spent arguing unsuccessfully that they should have not charged me a thing when my failed about 3 months ago. Probably not I expect.

Got the same letter today. Should be 800 bucks coming back to me. I'll take it.

So is this covered for all CR Passats even if you didn't have a failure yet?
Yep. The letter said the warranty is good for 6 years or 120,000 miles (if I remember correctly).

Good news. I'm glad they have decided to cover it under warranty. If anyone can get their hands on the recent/newest official tech instructions for replacing and flushing, that would be nice to see.
I have the "tech notes" which explains the process on my service papers. I know it's not exactly the same thing, but I can post it if need be.
I'm glad they covered it also, mine slowly grew cooler as the winter progressed. Planned on doing it myself shortly along with some distilled water flushes. Did see some fine print about diagnosis time not being covered and have read in threads where new coolant is not covered either.
Guess I am being greedy, hope I still have room on the dealer loyalty card. John

That would be useful. Please post.

Just received extended warranty on heater core; I have posted a new thread to that effect.

No, I started a separate thread because I see it as a different subject. This is about heater cores which have failed, my thread is about getting a warranty extension. Not everyone who may need to see the news of the warranty extension is necessarily going to be checking this thread regularly. Such as me.

Thanks Nord. I needed heat today and it seems the pass side is permanently stuck cold now. Drive side was plenty hot! I will investigate per your direction and report back. Thanks again.

I did something similar on our 2001 Passat. I had the brown waxy flakes from mixed coolant. I used an inline strainer I bought from Grainger. It is apparently designed for pumps used on boats. The screen worked well, but clogged pretty quickly.
Any links or part #s you can come up with? I just ordered a new oil cooler and core.
Headaches arrive in a week.

I have 2012 Passat SEl and my core (more likely ) gone bad too. I have heat coming from driver vent (by the door), center vents and no heat passenger vent (by the pass door).
I went dealer and they told it's not covered by warranty per my VIN number. Then, I called VW and they told me same it's NOT covered per my VIN number and nothing they can do.

I will call tomorrow and will ask them to update to return car!
