I have a 2004 Audi A4 and I decided to put some white turn signals in my rear lights. Now like I figured it's telling me that I have a tail light out on both sides. Is there anyway to get rid of the message on the dash without having to remove the lights and put in stock ones?

Cheers

Seems like the same problem that happens when upgrading to HID headlights on non-HID cars. The circuit is supposed to have close to a 0 ohm load (a bulb is basically a short to ground). The led bulb you put in has a very high resistance and is read as an "open" circuit, telling you the bulb is burnt out.

Only thing I know of doing is putting a power resistor in parrallel with the LED bulb, but that requires a little wiring. You'll have to splice into the wiring harness and if at any point in the futur, you go back to standard bulbs, you'll have to remove the resistor. I'm also uncertain of what resistance you'll need to use. I'll have to check my motorcycle...I did the same thing to get rid of the fast flash after I put in LED's. I think an 18 or 12ohm resistance worked. Which will run a little cooler than if you do a straight ohm's law calculation, which yeilds: 12v=5A*R, so R=12/5, which gives you 2.4 ohms. 2.4 will work, but it'll get hotter and there's no point if you can get away with a higher resistenace.

I'll get back to you after I check my bike.

thanks for the info
