Hi guys.

I have a CC-ID 134 fault code on my e90.

I have read other threads and changed the whole light unit, back plate and new brake bulbs but I still have the fault. I have also checked all wiring that's easy to access and no obvious damage.

Of note, if I leave the radio on with the ignition on, after about 5 mins I get the battery warning so assuming its bearing the end of its life.

I also have a tow bar fitted which is "spliced" into both rear lights but had that 2 years with no problems.

Any idea how I can get rid of the code or what I am missing?
