I bought some from ebay that were recommended on a thread here to not throw up any errors. It's true, they didn't but one of them just flickered and went out every time so I put the normal ones back in.
Wouldn't mind some decent ones that actually work though.
side lights will be here at the end of the week, the plate lamps will bring up an error as the B7 bring up an error when using an LED. i have a halogen version which if you check my sig thats what you get.
