E320CDi (W210) Glow Plugs And Cruise Control

[Dave K]

Further to my questions in another thread about changing glow plug #6 on an E320 CDi (W210), I've discovered that the cruise control has failed at the same time as the glow plug light coming on after startup. Could these two events be related? Do the two systems share a common fuse or relay?

TIA

Cruise problem could also be the actual control arm itself. A common problem on W210's, I'm led to believe. Not too expensive to sort.
