lighting issue

Ok so all my rear running and brake lights work but on the dash it is always telling me check rear lights and check brake lights. Any one else have this problem? I am baffled.

Common problem cured very simply. The electronics constantly monitor the circuit resistances to see if the bulbs are OK. If the contacts are slightly corroded or the bulb is on it's way out then it will be fooled into thinking the bulb is faulty even if the bulb is working.
I suspect poor connections seeing as you have more than one bulb circuit misbehaving.

m3matty is dead right.

I used to have the same problem on my 528e.

You can get this if you replace individual bulbs. It is better to replace pairs of bulbs.

Check this one. Its very common for this lamp to fuse itself to the housing so you will have to replace this assembly and ur done.
