What if the bulb housing connector is corroded? Is there a replacement part for that grounding tab?

If you're talking about the small ground blade inside the 8-pin taillight housing connector, you can try using some sandpaper to lightly clean up the contact area. If it didn't work, you'll probably need to buy a new taillight assembly which I believe is $30-$40. My left taillight assembly connector's ground blade was slightly corroded and a little bit loose but everything worked fine after I slid the new ground splice connector onto it.

You guys rule. I was beating my head on the dashboard. Couldn't figure this out.

I will be doing this repair this weekend.

Thanx.

I have a similar problem, but it is with my after market EAGLE EYES LED tail lights that I installed about 5 months ago... The lights came with a whack of resistors, which keeps the "bulb out" warning off. But just recently, intermittently I have had this warning come up on my dash.

The thing is, BOTH sides (left and right) come on and off TOGETHER. I have yet to see just one side come on.

Is the Bulb Out sensor in the rear independent like the headlights are? (only one will come on, whichever one is out)?

I was about to do the fix mentioned on the board here, but it seems like since they are both coming on Exactly together, it may not fix my problem.

Feel free to PM me or just post here

Thanks for the help guys

The rear bulb sensors are independent. It sounds like you may have resistance/corrosion issues on your taillight assemblies ground wires. Check for corroded pins or melted connector pin holes in you taillight assembly's 8-pin connector. I have the factory taillight assembly. When idling or driving, one taillight warning would appear but both taillight bulb warnings would appear when I stepped on my brake pedal.

It wouldn't hurt to do the fix. It costs $2 and takes 5 minutes to do each side.

thanks refimail. went and checked the connectors, they seemed ok. I had this problem with the ground pin before i did the led conversion, used some electrical contact cleaner. Nick from Jlevi recommended I check the license plate lights. Neither of them were working.

Upon removal of both lenses, there was almost a half teaspoon of green, corrosion powder came out! It was all over the bulb and the ballasts of each of the bulbs. The damage looks to be too intense to clean up and repair it, so it looks like i will be replacing some parts.

Ill have to do a little research to find the part name that needs replacing, then figure out how to get at it!

Thanks for the help guys

I tried doing this. It didn't work.

I don't have the tabs so I just soldered the extra wire to form the ground.

The tail light indicator is still on. Could it be anything else? I checked for corrosion, and there is none. All the bulbs work.

I guess it's not a big deal, but I'm just sick of staring at it when I drive.

Does anyone know of a link to a new tail light assembly? Thanx.

- Did you solder your ground line to the metal strip where the tab should have been? Not all the metal strips in the taillight assembly are using the same ground.
- Did you check if your license plate bulbs are out, like shock29? Those license plate bulbs also use the same warning light as the tail lights.

You can try to look up the tail light assembly part number in www.mileoneparts.com or give them a call if you can't find it.

Go into your trunk and remove your rear tail light assemblies. Disconnect the black 8-pin connectors and see if one of the pins in each connector (leading to a thick brown wire) is burned/melted like this: http://forum.e46fanatics.com/showthr...ted+tail+light

If so, perform the following BMW service bulletin: http://www.bmwtis.com/tsb/bulletins/...p/B630306g.htm

If the connectors are not burned, follow the procedure called out earlier in this thread.

Good luck.

Thank you so much for this write-up!!
Never again will I have to see the rear taillight warnings, definitely post this in the DIY section-I'm sure there are still a lot of E46 owners dealing with this everyday

Endless thanks for this write up! This was an extremely easy and cheap ($8)DIY for what I thought was going to be a costly repair. The warning light for the turn signal has finally turned off and the signal works like normal again. Thanks a million!

Easiest fix ever. Thank you for posting this. I got the dashboard warning light, checked, and found my passenger side taillamp was 50% of the driver's side.

All bulbs were fluctuating at the same time. Took off the plug and found the pin on the taillight side was good but the socket on the wiring harness side was discolored and had seen heat. No major damage, but no longer a good connection.

I did exactly this, but used one of the 3M clips to connect the wires.

Dash light out, both sides now bright again.

You don't need to disconnect the battery. Just make sure the key is off.

Make sure you add the extra grounding wires or you'll see the problem when the connectors corrode again.

I had the exact same problem on my 2003 320i on the passenger side rear tail light. I tried everything you guys mentioned and nothing worked. I went to see BMW service and they said it is the harness and it will cost $600 to fix here in Canada. Went home and out of frustration, I took everything apart and inspected the harness to look for defects. 3 hours later I noticed that the driver side had a slightly blackend bulb, so I changed it. What do you know, that worked. I guess the driver side alters the resistance on the passenger side and that solved it. Saved $600 bucks. Hope this helps others out, I almost gave up.

Cheers,

I also had this problem. I unpluged the black connector and cleaned the bayonet fittings with some coarse sandpaper. Fixed the problem straight away.

I don't have that little tab. Where can I ground it?
