No heat passenger side again

January of 2017 I had my heater core replaced due to no heat on passenger side. Worked great last winter but now same problem. Has anyone had this happen to them.

Make sure the recirc button is pushed so you don't get cold ambient air mixed in

yes some are on a 3rd core

It's going in tomorrow to check. Also an airbag recall

The heater core clogging is a symptom of a larger problem. Volkswagen is only addressing the symptom - not the actual problem. Expect this to continue happening and likely get worse as other coolant heat exchangers (oil cooler, EGR cooler, perhaps even the main radiator) get clogged, as well.

Just wonderful

Any my guess the problem is the design of the coolant system operating outside the coolants designed specifications.

But that's just my guess.

There have been reports of multiple flushes helping out, but and dealer is going to be have to lead to that pond for them to take that drink, they will prob keep tossing cores at it.

This is one of a number of reasons (on core #2) I'm doing the buyback next year....

Two heater cores replaced under the extended warranty on my 2014 Passat.

Here are a few ongoing discussions about heater cores.
