Turn signal indicator shutdown

A common issue, is failure of the hazard/flasher relay; it is integrated into the emergency switch, depending on the year is on the dash or under the hvac controller or stereo. Sometimes, they can be revived; using some contact cleaner but in my case, I had to replace mine, to finally fix the issue.

This is the cleaner; that i use:

CRC 05103 QD Electronic Cleaner -11 Wt Oz



Here in the USA, this product; is sold at all auto parts stores, hardware, home improvement stores but the best price is @ Walmart, in the auto supply area ($7-$10 at most stores and under $5 at Walmart).
 
Good question, as to the "country of origin"; I have noticed, on my 2002 New Beetle Turbo S, most of the original parts, were made in Germany or Mexico. As time has gone on and I replace genuine vw parts, the new ones, typically are made in China or in Eastern Europe, the Czech Republic, Hungary or Slovakia. The production costs in the former Easter Bloc nations; are locations, that are cheaper to produce parts from, kind of like many auto parts are made in Mexico, compared to the USA or Europe.

As to part # and look variations; I have noticed, that VW many times, will change suppliers or the suffix, Alpha letters will change, denoting a revision, to the part. As a part ages, part #'s can change and suppliers, may put different markings on them. I don't know, if there was a particular issue with your version of the part but VW, does seem, to update their parts and try to improve, failure prone designs. Classic examples of defective parts revisions: were the particularly failure prone 1.8T coil packs, brake light switches and the black colored coolant temp sensors. In some of those cases; they changed the color of the parts, to show, a visual indication, they were the later revised part (coolant temp sensor; went from black to green).

For correct parts, VW looks things up by your VIN #; hopefully, it is correct. I usually compare the electrical connections and the overall look of the part, hopefully, it is the right one. Wherever, I have gotten wrong parts; my local vw dealer, has always made it right and gotten me the correct part I have needed.

For example, the 1.8T 710N diverter valve, was originally supplied by Bosch and now, VW gets them from Kayser, same part, different markings, logos but functionally the same.

As to the longevity of the part; I suppose, it is anyone's guess; I assume, your original lasted 13 years, thats pretty good and hopefully, it will last another 13 or the life of the car! :)
 
I cleaned my old flasher relay's contacts, internals, tries to fiddle with it, etc and tried to get it working agaIn. While, it seemed to start working better; it was never right and flaky. A new oem one, was instantly better, worked correctly again, had a different sound to it and I haven't had any problems, since then. A solid fix; job done.
