Hi,
My wife's 2003 VW Conv started having a fast blinker, first on the right, then both. All bulbs are ok and I found the posts that suggested some WD40 by the blinker arm where it connects to the column or to replace the hazard/flasher relay/switch (great post on that one -- it was easy to follow and I replaced the switch pretty quickly). However, I tired both and neither one cleared up the fast blinker issue. Any other thoughts as to what it could be before I take it in?

Thanks,
greg

Had same problem

Had same problem with left front turn signal, replaced bulb, problem came back again. I bent the tabs that makes contact with bottom of bulb out towards the base of the bulb, have not had problem since. Hope this helps.

Helped alot...worked

Thanks knewbug...cleaning and bending the contacts worked like a charm. Wish I would have done that first, but when both blinkers went out at the same time, figured it had to be the hazard relay (I did leave the new one in since you can't return electronic parts at the dealer). At any rate -- thanks since I wasn't sure where to turn next. If anyone has the same issues with the turn signals, I'd do:

1) Replace bulbs (if necessary...mine were ok)
2) Clean and bend the contacts on the front blinkers (thanks knewbug)
3) WD40 by the turn signal (saw it in a forum, not sure how much it helps)
4) Replace the hazard relay/switch (tribangle has a great HOW TO withi pictures...it is pretty easy:

Thanks to the folks in this forum for all the assistance and saving me alot of $$...

This is also a solution for the brake and tail lights dimming or acting erratic. Clean and bend inward the brass circular contact (ground) to make a much tighter contact with the bulb's shell.

Just found this post. Have a 2005 GL Conv, with the fast left blinker. Changed bulbs, no change. Had seen the WD40 remedy, that didn't fix it. Just now finished bending the contacts on the front left signal light. Problem SOLVED! took three minutes. Thanks very much. I was worried that it was some electrical gremlin that would require a VW specialist.

Sometimes this helps fix the problem, it can be a temporary solution, however but if the problem comes back, it typically is, from loose bulb sockets, damaged from from years of heat from the bulbs (usually indicated by brown color, loose bulb, etc). In that case, a new socket is the fix; get genuine vw parts for this; they work he best, check ebay for the best prices ( search for a ebay seller "quikparts"; a vw dealer selling parts online).

You were correct. It lasted about a week. Even though the bulbs are not loose and there appears no damage to the socket, I ordered a replacement socket thru the only Amazon supplier that had one at an outrageous price for a small piece of plastic and contacts, and the only one in stock. In tracing the shipment found that it's shipping from Latvia. So far it's spent 14 days in Latvia and still no update on shipping. Today the right blinker started the same fast blink. No loose bulb, and did the same as the left to correct. Just have to wait for the replacement part and then locate another source for the second replacement. Volkswagen should be proud of their high quality. NOT !

Yeah, VW is known for electrical issues; plastic plugs breaking and bulb sockets getting loose, terminal ends losing tension/contact and insulation peeling off the wires in the headlight assembly, are common issues. After 18 years, i've replaced most of my light sockets; to fix the looseness issues and now my lights work as they should! :)

PS: i have ordered parts from the same Latvian vw supplier; the covid issues, maybe slowing the shipping time frames. Check th ebay seller "quirkparts"; for faster shipping and good prices on genuine vw parts.
