Fast Blinker Help

I researched several post on this subject and thought I would let everyone know what I found with my rapid blinker troubles on my 2001 325I. My left blinker had a mind of its own and would rapid blink when it felt like it. On previous cars I've owned(non BMW) when you get a rapid blinker it means you have a bulb out. Not the case on a BMW from what I've read here. All of the left side bulbs were working but just to exclude them from the equation I replaced them all. The problem still existed. I removed the new bulbs and cleaned all the contacts on the bulbs and their housings, still had the rapid blink problem. I poked around a little more and decided to disconnect the molex plug that plugs into the rear tail light housing(remove the panel inside the trunk where the lights plug in) I believe it has 5 or 6 wires total. Once you disconnect the plug from the panel you will see the terminals are numbered. On terminal # 4 (gold/beige wire) I had some corrosion! I cleaned off the corrosion on both the terminal crimped onto the gold/beige wire and the terminal inside the light housing. I've been driving it around all day and it seems like the problem is fixed! I hope this may help someone fix the same problem or at least give them a starting point to troubleshoot.

I did too! Nice German car and a crappy blinker don't mix well in my book. Let me know how it works out for you!

After reading those 2 links it looks like this is an extremely common problem! Looks like all of our stuff was either corroded or burnt up! I researched several post but not all of them. Thanks for the links!

I had the same problem, it was so annoying, but I recently installed LED tails and the problem went away

Fast Blinker Problem Fixed!

Wow! I suffered w/ this problem for 6 months. I was afraid to mention it to the dealership, as it would have most likely resulted in the usual $600 extorsion. I cleaned off the #3 & #4 wire contacts on the tail lights, (takes about 2 minutes), and this issue is totally resolved.
Thanks again for sharing this information.

I know this is a rather old thread but I found it due to having the same problem with my 2001 330Ci convertible on the left turn blinker. It starts out fast and then it goes to normal. If I turn the blinker off and then start it again, it is normal. Then after awhile, if I use the blinker again, it does the same, fast to normal. I have low milage on my car just reaching 50K. I took the Molex plug out of the light terminal and my #4 housing looked alittle darker on the plug housing where the numbers are shown but the opening is too small to get anything in there to clean it out. I tried to take a safety pin and poke in there to clean it alittle but it didnt have any effect. Now, there is a white piece that looks like it can be removed on the side of the plug and it looks like it would open the plug further and show where the wires are connected to the plug itself. Is that true and can I take that off? It also looks like it would help hold the plug into the light terminal. Not sure here. Help?

My 2001 330Ci coupe does this with the right blinker. If it blinks fast continuously, I just hit the brake pedal to light up the brake lights and it will quit.

Ill try that for a temp fix but it is like what someone else said about a similar problem and fixed it. "The ultimate driving machine shouldnt be doing annoying things like that."

Others have hit on a corrosion problem with these back blinkers that happen over time. It is an electrical issue that BMW decided not to address w/ a recall. I want to fix mine w/o taking it into a shop and spending money on something that seems so simple to fix.

Guys, check for corrosion on the socket, that's what caused it for me. Also, sometimes the solder on the base of the bulb itself gets worn and no longer makes a good connection. If you have corrosion, scrape on it a little bit with a piece of sandpaper or file. If it is the bulb, get a new one. The sockets are cheap too if they are shot.

Easy fix

This is an easy fix, simply splice into the ground wire and wire it to the metal frame of the housing. That is what I did. If you remove the connector you can see where the burnt up connection is.

Glad I found these posts...my left signal flasher was blinking very fast for several seconds then would return to normal....all the bulbs were good....went out in the garage, popped the trunk lid on my 2001 325, pulled the light assembly, and pulled the pin connector block apart. Yep.....#4 was all corroded. Used some emory cloth and electrical contact cleaner and the turn signal now works fine.
