Richard just wonder after you changed out the fog and side marker to LED, do you need to code it to make it work?

Thx

As per Osram's bulb chart, our cars take 7507 bulbs, AKA PY21W bulbs, AKA 1056 bulbs.

NOT 1156 bulbs.

Bulb cross reference chart: https://www.superbrightleds.com/car-...oss-reference/

Check the manual ... Front and rear turn signal bulbs are the exact same type.

I have unused brand new interior LED for the F25 X3 for sale if anyone is interested.

You're wrong. Even Sylvania's bulb Finder shows them as different, matching up with the other link I posted:

http://www.sylvania.com/en-us/applic...l=2211&make=13

And even in the manual, it clearly says they are different. PY21W for the front, and P21W for the rear. P21W bulbs are the same as 7506, which is what the bulb finder chart above shows.
