Default Glow plugs

I recently acquired a 2013 TDI Beetle... No where on the dash cluster is the display for the glow plugs. We are having a heck of a time starting in cold (below freezing) weather. In the manual there is a reference to them but again nothing on the dash cluster. Am I missing something?

The manual should have a picture of the instrument cluster with all the warning/info indicators pointed out - that doesn't show where it should appear?

I've scoured the book for a photo of the page...the only reference to the glow plugs is in the starting procedure... I'd show a photo of the page but I don't know how to attach a picture on this forum.

The preglow lamp should come on when you turn the key on no matter what, hot or cold... just the length of time it stays on will vary based on how cold the coolant is.

So you are saying the lamp NEVER comes on? That is not right, something is wrong. I'd ask the engine controller, as it communicates with the glow controller, and see if a fault is present.

Thanks for the words of wisdom...yes that as well as turning off all power draw before trying to start. Still curious about the lack of glow plugs indicator on the dash.

is it just an issue starting due to no glow plug warming time or is it sluggish to start after warming the plugs after 30 seconds?

I am in Texas so not really cold here. That light comes on and goes out really fast here, even when the temp has been down to the 30's. You have to be looking for it or you will miss it. Here anyway.

Scan for DTC's (Fault codes). A local parts house will do this for you for free. Just don't buy garbage Chinese parts for your Dub from them. My best guess, look for a DTC relating to the CTS (Coolant Temp Sensor) which does regulate glow time.

Even if the dash temp gauge appears to read correctly, still scan for DTC's.
