Frustrated and need a little guidance...

I've been living with a CC-ID 134 error on my 07 e92 335i. Looks like a rear lamp malfunction. So, I checked all rear lights and there's not one bulb out. Nonetheless, I started to replace components and still haven't found the culprit. Please help!

Parts I've tried replacing both lamp modules with bulbs
63217174407 & 408

and even
63217207528 Bulb sockets

Still have the error. Any ideas?!

CC ID 134 is right rear brake light. There are 2 brake lights per side, so I'm sure you've inspected and or replaced both by now?

If that doesn't work, clean the contacts with WD-40 and a Q tip.

Do you know what the manufacturer is on the bulb, I had the most success with sylvania as cheap non name brand ones tend to fail and/or cause problems.

I noticed you've replaced what seems like everything and at that point if you are sure the lights are working maybe just get the car coded?

Thanks for responding Jeff! The bulbs came new from BMW with the entire module so I'd imagine their good. I will try your WD40 method. If that doesn't work, are you suggesting having it coded to remove the error?

Yea, I mean your only other option is to have BMW diagnose it. That could cost up to $150.

You've done everything I would have done otherwise, usually it's just a fault contact but if they are new contacts, new modules and bulbs then I'm stumped.

Jeff, you're my boy. Helpful comments and great service when I've made purchases from you. Even when I had a faulty item. You are top notch my friend.

Finally fixed it!

Unsure what finally did the trick as I did it all in one shot.

Removed the module.
Cleaned the two contacts on the module.
Cleaned the probes.
Removed the housing from trunk lid.
Cleaned contacts where socket is inserted. Restarted the car and moments later, error is gone!

Thank Jeff and I hope this helps someone else.

Do you recall the brand? The cheap bulbs are usually problematic.

OP, I have nothing more to say than Thank You.
I've spent over a week trying different solutions and all it took was a simple cleaning with WD-40.

Seriously, thank you.
