Glow plug issues

[Bradster]

Hi guys, I hope you are all well in this rubbish lockdown? I need some help please. I have an solid engine management light on my 08 Leon 2.0 tdi FR.

Code reader gets P0670 Glow plug module control circuit and P0671 cylinder 1 glow plug circuit. Any ideas?

I originally thought just a glow plug but now I'm thinking is it the controller?

Would you change all glow plugs or just the one?

Is the controller easy to do?

Cheers. Any help greatly received.

Get a VCDS scan before you start throwing parts at it.

If it is the glow plug then do all 4

Thanks R3k. My mate put his MAG tools scanner on it and got those codes. Isnt that the same thing?

VCDS is much more specific to the car so give more than just generic codes.
