I have a 2007 R320 CDI and I have never seen a glow plug light on my dash ever. Is there anyone here with the same or similar vehicle, and can you tell me if there is usually a glow plug light on the dash when you first turn the key, and where it would normally be?

Thank you

I have a 2009 R320 Bluetec and I can confirm that there is a glow plug light in the dash of mine.

Im going to assume my 2007 is supposed to as well. I have never seen this light on the dash. Do you see it all the time, like even when it is warm out? I have purchsaed a glow plug module after checking some codes and doing some diagnostics.

Thanks for the replies
