As I'm sure everyone here knows the E39 and newer vehicles have very sensitive OBD's. When I researched fitting my entire vehicle with LED lighting I was made aware of certain situations where an LED bulb would prompt a CEL.
The LEDs extremely low consumption actually fools the OBD into thinking the bulb is burnt / missing.
The bulb in question is a:
Philips X-Treme Vision 6000k 38mm festoon style bulb.
It puts off great light, doesn't look cheesy etc. It also is completely weatherproof / enclosed which makes it perfect for license plate applications. It's even fitted with its own heat sink.
This really stinks because other cheaper LEDs have not triggered a CEL but burnt out after 3+ months. The LED seems perfect but I'm guessing it had no built in resistor?
