As you may know the bulb warning system on the 2010+ cars is much more sensitive to LEDs, as such normal LED number plate bulbs (even with resistors) put a bulb out message on the DIS. However some guys over in the USA have fixed this issue by using a LED load equalizer - see here for the details: Fourtitude.com - DIY - The $17 LED License Plate Fix
So I bought all the required parts from the same place as in the link (came to about £23, and the shipping from the USA only took 5 days) and got on with it. The outcome is I have great LED lights and no errors on the DIS or in VCDS logs. I've been driving around for a week with them in and no issues at all. The LEDs just look so much better, just need to do my fogs now and I'm all LED'ed up!
Just a few tips for anyone doing this:
Here's some pics:
- The equalizer gets hot, crazy hot so make sure you mount it away from anything
- The wire to the lights is thiner then the equalizer wire, so make sure you really push down on the connectors so it bridges both wires, at first I dint do this, and got errors.
- Go easy on the screw for the bulb holders, its hard to get to them with the angle and they are as soft as anything, don't round them off!
- The hardest bit is refitting the boot panel, best way is top on first then slide it over the boot lock.
Any questions let me know
