I can confirm mind DID work and noticed a couple months ago it went out one day. Took it into the dealer, put a refurb cluster in and gave it back to me. Still doesn't work. Car back in currently. Tried bulbs and even dropped in a brand new cluster, still no light. VERY odd! Because I am 100% it did work at one time all the time whenever the dash lights were on NOT only when in the "E" zone.

Well they are giving it back to me because they gave up as usual. Yet another "can not duplicate" to ad to the LONG list.
