I have a 2014 Passat TDI with 70 K miles that has experienced an overheating problem. I was on a trip and the check engine light came on with a P2457 code (EGR cooling performance) but the car ran fine. I also experienced a plugged heater core which may be related to the P2457. When I got home my VW dealer said my car overheated and damaged the Intercooler pump and the coolant reservoir. They based this on data from the OBD2 scan. However, the temperature gauge never went above 190 degrees. How can an engine overheat without the temperature gauge going up? They said the thermostat was stuck shut and changed it along with the other components mentioned. The bill came to $2400 which really surprised me. Labor for changing the thermostat was over $1000. How is this possible? The car runs fine but I still have the same "burnt antifreeze" smell from the engine bay that I had when the fault light came on. I am not confident that all my problems are fixed. Any thoughts?
As for the clogged heated core, they replaced that under my extended warranty. If the EGR cooling was at fault should that have been covered under the warranty for the emissions system?
Confused in Florida!
