I've read various threads about what required. To he honest it all looked like a bit of a faf so I decided to try some ebay bulbs with built in resistors but none of them worked. They'd blink a few times before the warning came on and the car switched them off. With this in mind I was sceptical when I read a description of some bulbs that were compatable with the B7 canbus. I decided to give the guy a call rather than place an order online so I could check the description was accurate. The guy (James) assured me they would be fine if I bought the 8 led version as they drawn slightly more current. He said I could have a refund if they never worked so I thought what the heck. First off, there not what I would consider cheap. I guess if you had topay for resistors, wires, scotch locks etc its not that bad but next to other leds they're pricey Next problem was they don't fit out of the packet. They're too wide and need to be filed a little first From this to this As with all leds they have to go in the right way round or they won't work As you can see,no wiring changes at all. And the results.... Sorry about the **** phone pics, can get better ones if required. So what about the dash warning? Nope, all clear. Now I've only had them in a couple of hours so may have to post up in a few days to confirm they're still ok. If anyones is interested here's the link to them, I'm not affiliated to the seller at all. WHITE CANBUS ERROR FREE 501/W5W/T10/194 SMD LED Sidelight bulbs If anyone has any questions stick them up.
