The backlight for the fuel gauge in my 2012 Laguna Seca is acting up. 

 

When the headlights are on the gauges reduce their brightness and the fuel gauge is dimmer than the rest and sometimes does not illuminate at all. The needle always illuminates correctly but the gauge graphic will flicker, be dimmer than the rest of the gauges or go dark. When the gauges are in daylight mode, headlights off, the fuel gauge looks just as bright as the other gauges. 

 

Haven't found too much on this issue online which leads me to believe it is an isolated event. How easy is it to get the gauge pack out?

 

Thoughts on this would be helpful.

 

Thanks

It shouldn't be too hard as both myself and 302HP removed them to add our LS dash gauges. 302HP did a nice write up on the install so look up his post.

TS:

Thank you for the kind words.

Here is the link to the LS Gauge install which includes the IP R&R:

Please let us know what you find on your fuel gauge light problem.

PS: Yes Imwould agree, it is not a common problem, I would start with checking grounds.

Good luck,
302 Hi Pro

Dash lighting is supposed to dim when headlights are activated to preset intensity level. Never having my instrumentation apart, I found in the past they're all mounted on a circuit board, stripped with the bezel(s) making them appear as all individual gauges.

The problem appears as though it may be a major headache. Sounds as maybe a hairline soldier crack or circuit board ribbon fracture or defect. Actually an easy fix but you have to disassemble the entire dash to get the board out retouch the flaw with a low wattage solder iron and reinstall.

Where did all the old fashioned junk yards go too? There might be 1/2 dozen exact replacements in junked cars sitting there. Would go in on a Sat. morning w/socket set and rummage through it all. On the way out would stop at office with salvaged parts. They were negotiable on prices and half the time would just give them to me and were clueless as what the parts were for even, especially the sensors.
