I got a 2012 jetta TDI with 28k miles and my glow plug light is flashing. I haven't got a chance to pull codes, and without codes you can't tell what's wrong. But what have people seen as the problem ?

VW Mk6 glow plugs warning light - the glow plugs dash light has dual meaning, so be sure you read this carefully.

CONSTANT - if the light remains on and constant, it means a fault in the glow plug system. You should not start the engine until this light has turned off, and will generally take a few seconds longer to turn off in colder conditions.

FLASHING - if the glow plug light is flashing it means there is a fault in the engine management system and needs to be diagnosed & fixed accordingly

On a new car, the glow plug light flashing indicates a serious engine malfunction. Possibilities include, but are not limited to, a failed turbocharger and a failed high pressure fuel pump. It could be any number of things, so step one is to scan with VCDS and find out what it is unhappy about.

I forgot to give an update... After I pulled codes it was P045F EGR Intermittent stuck closed. After I cleared the codes and restarted the car I haven't seen any other lights

On my 2011 Jetta it meant the barometric pressure sensor was on the fritz.
