Location of firewall gromet for cable routing to engine campoartment.

[Shak123]

Hello

I need some help with identifying the location of the firewall gromet on a 2010 - A6 S-line. I need to feed a cable to engine compartment. I have had a good look but failed to identify it.

Any instructions on how to thread the cale and how to remove trims would be helpful.

thanqk you
