Just had my heater core go on my 2014 passat. Atleast its covered under the extended warranty on the heater core.
After a rather chilly ride to the East Coast last Winter for my front seat passenger (aka wife), we got the heater core replaced under the 10/120K extended warranty, and the system WAS completely flushed at no cost to me. I had read another post of someone whose dealer wanted them to pay for the flush, and I was prepared to go in and say "Then don't flush it. Put the old coolant back in, and when it plugs again, I'll be right back in here for another core." But I didn't have to do that, it was all good.My dealer replaced my heater core under an agreement with vw. Splitting cost between the 2. That's what they told me anyway. Charged me $225 for a coolant flush. Which I thought was bs. Left the dealer and the heater never really heated up going down the road. Argued with the dealer and they kept the car and ran more tests. Came back with changing the heater core again. And come to find out they replaced the egr cooler also. No charge this time. Was wondering if the first time they just tried flushing it and it seemed to work idling in 1 spot. But going down the road was another story.
Car was a 13 with 43000 miles.
There are other threads dealing with this issue, and, yes, it is a known problem. VW has never admitted to a specific cause, AFAIK, but there is a general belief among many that the excess heat produced by the emission control system denatures the new G13 coolant, causing the core to plug up. We are among those who have had the core replaced under warranty, and I wouldn't be surprised if we had to do it again this winter. There won't be a winter after that, because we are turning the car in late next year.<snip> How is it this has not been found to be a defective implementation of heat by now? And how is it there are corrosive elements in the tubes/hoses? Seems like there are LOTS of people having this very issue.
