VW Mk6 Golf, Jetta, Beetle, Sportwagen TDI forum
We've just picked up a used 2014 Jetta TDI. Very happy with it overall, but just curious how long the glow plug light should be illuminated during cold (<10F) starts. It comes on currently for 2-3s and then goes off while the key is in the run position (before cranking).
Is this as expected or...
