Turn Signal blinks fast?

Normally I expect this to indicate that the bulb is burnt (or a bad connector) but neither appears to be the problem...

So... should I assume it is the switch? If so, is the switch in the stalk? I imagine that'll be a pain in the arse

Re-seat all of the bulbs, cleaning the connectors with rubbing alcohol when they're out.

Even having a different *brand* of bulb will sometimes cause the problem. When one of my front Solaris Invisibulbs burnt out, I replaced it with the OEM bulb while I waited for a replacement. The turn signals on that one side blinked faster...

Mine show bad rear bulbs all the time. Had one go out and bought a replacement bulb at autozone. Bulb worked but warning light stayed on.
So I bought ALL new bulbs while at autozone

Of course that didnt help either. Closest freaking dealership is 110 miles away

The previous owner which goes to that city alot said he would pick me some up.... 2 months ago

I guess Ill have to order some sometime.

Same problem with mine and only replacing both front turn signal sockets solved it.

Similar story for me.

I had the warning light for a FRONT signal go on and off at random intervals. The blinkers would sometimes go fast, sometimes slow, sometimes not at all. All of the bulbs seemed to work. I was convinced it was the switch. On an unrelated trip to the dealer, they found I had one bad TAIL light and only after replacing it and both REAR blinker bulbs did the problems go away.

Apperently the ECU doesn't like it when several bulbs start to die.

I had that problem on a Honda Odyssey. I had just replaced the bad bulb but it was still blinking fast. Turns out I had intalled the lamp the wrong way. Just check the bulb you last replaced again.

LEDs won't solve your problem.

New sockets probably will.

Mein Auto: 2002 325Ci
I was having the same issue in my 2002 325Ci. The right rear blinker showed up as burnt out and the signal lamp started blinking faster. I popped out the bulb assembly and wiggled the lights. (Took them out swapped them around and such) This solved the problem for awhile, but eventually it started up again. Each time the CPU says a bulb is out I just swap the lights around and it seems to clear things up. I'm thinking there might be a connection problem or possibly a ground that is being bumped loose while driving. Its a little annoyance but still a lot cheaper than having it fully replaced.

Anyone else have a similar problem?

Intermittent bulb problem

I had a similar problem where my left side turn signal blinked fast and I had a bad bulb indicator on the front left. I replaced the bulb but problem and bad bulb indicator remained. I removed the bulb and inspected the socket. The flexible contact at the bottom of the socket had been sprung down and was only occasionally contacting the bulb. I used needlenose pliers to spring it back up. Problem solved. Make sure the switch is off when you do this to prevent blowing the fuse.

front right turn signal

Interesting, my right front turn signal seems to be out now and was wondering if anyone would know if it's possible to take my left front turn signal bulb out temporarily and put it on the front right side to see if it's a bad bulb? Any cautions or words of advice on this since I notice someone mentioning to make sure the fuse switch is turned off which I don't really know much about since this will be my first time going under the hood for myself?

Yep, it's easy to swap the bulbs. For instructions on removing the turn signals, see the first part of the My330i.com garage about swapping your signals for clear corners (same procedure, obviously).

If your 325i is a 2002-2005: http://www.my330i.com/mod31.php

Wow, just checked out your site with all of your detailed photos on how to's. Very impressive

Quick question since mine is a 2003 325i, can I remove the turn signal bulbs by hand or do I need a cloth and not touch the bulb directly?...and if it is a bad bulb and needs to be replaced would I be able to know which bulb in particular it would be and where to get one? I read some other post that someone purchased the wrong one in that they looked similar and didn't have any labeling and mentioned to not go to the dealer since they'll charge much higher than a local auto store?

Thanks a bunch for the quick and insightful reply. Much appreciated

The trick to making the bulbs continue to work properly is the special electric grease you can put in the socket before you put the bulbs back. I wish I could remember what it is called, but ask the auto parts store, they can get it for you. This worked for my 2000 323i that used to show bad turn signals every other day, doesnt now though....

Yes, it's good to handle any bulbs with a cloth.

How can you tell which one? Um... turn on your hazard lights, get out of your car, and walk around looking for a light not blinking? I believe you should also see a notification on your dash showing which is out - I do anyway...

My dealer is cheap - $3 or so for a bulb.

I believe it's just called 'dielectric grease'

Yup dielectric grease is it, as this is the same thing you use for spark plugs cause it reduces corrosion and also is formulated to reduce impendence and allow the electricity to flow more smoothly with less resistence. Should help out.

Mine turned out to be the tag lights that were burnt out. Never dawned on my to check those since they are tail lights in my opinion. Replace the two bulbs the light the tag up and no more warning light now.

There are tabs to squeeze on the back of the housing. Squeeze and pull basically.

You just press a screwdriver down in this hole, then pull the entire assembly out..





What can't you do?

My driver side flasher blinks too fast at times, then acts normal. I've also had a headlamp indicator light come on, but all the headlights were working. It too, returns to normal. Who knows?!
