2009 TDI. The dealer did the fix. Now I am getting EGR Insufficient cooling performance - P2457.
They are refusing to cover it under the extended warranty. They are saying I may need a new radiator, expansion tank, radiator cap, radiator fans.
This car has been wonderful. No check engine light for years. DPF not cracked. All working. Now I have a piece of junk for a car that can not be driven. They mentioned numbers in the $1000s and are not saying that any of it would fix the CEL.
Called VWAG. They are sitting on the fence and won't say anything.
Personally I am totally disgusted with this whole thing. Should have done the buyback.
I have a very good idea of what is wrong but they have decided that replacing things that are not broken is the way to go.
All I can say to anyone signed up for the fix - take the buyback.
A little more technical info - I can hear boiling coolant in what I think is the EGR cooler. I suspect that EGR exhaust flow has been increased to lower NOx during combustion. The EGR coolant flow is in series with the heater core. And I know the heater core is clogged. So it makes sense that this error code would come up. But the dealer has said the heater core is good. I know otherwise but they insist they know what they are doing.
