airbag and seat belt lights on
Hi there - I know this has been discussed extensively ....so my apologies upfront if there is a better place to start searching for this...
Two months ago the airbag and seat belt lights went on. I replaced at the time a few rear light bulbs from stock to led...and I do think that this might be the issue. I did not try to replace them back to stock and see what happens so I thought that someone might have happened through the same process in the past. Any thoughts or ideas on where to start from? I am not planning to take it to the shop until I can do some research and hopefully permanent fix myself...and learn from this beautiful piece of machinery!! Thanks in advance and all the best! I am sharing one pic with my 964 C4 cabrio

first try is to use a durametric or hammer etc to reset the lights. see if it goes away and clears. if so, you're good, if not, you may have an actual ABS issue.

Did you mess with the clock at all recently?

thanks Spyrex! I guess that a more sophisticated OBDII would do nothing here right? These scanners are a bit expensive for my budget ...probably a local rennlist or PCA friend might help me out here, please! Another option I guess is going to my local Porsche shop and ask them for a quick reset

hi Black 3.2! Not at all...clock is working as it should with no lights. Again I installed led lights recently (lincense plate, Parquing lights and rear brake lights...). Could this be the issue? Thanks all for your knowledge and advice!

durametric pro maybe personal will work
bosch hammer
torre odb scanner
or a piwis with the right software version and adapter.
maybe a local can help. It takes all of 2 minutes to read the codes and clear them.

I think changing the bulbs to LED did not cause the issue. I changed all my bulbs to LED a few years ago with no ill effect and have a couple of friends who did the same. LEDs draw less power than the old incadecent bulbs, yes, but I fail to see how that triggers your warning lights- unless you created a short somewhere when you changed bulbs. A quick spike can do all kinds of "bad" things with your electronics.
Read the stored codes - that should answer your question.

thanks Spyrex! I have a OBDII to OBDI cable but not sure that a good modern scanner would do anything here as the system in our cars is pre 1996 hence OBDI. Can someone confirm by using a new scanner with a OBDII to OBDI cable would solve something here?

This works well, you will need the round adapter cable. And the software (a freeware software that runs on windows and is old and rudimentary, but it WORKS) is a little clunky:

This is a good tool to have. I use this + a durametric since I have other Porsches with ODBII.

A known problem on these cars is the connections that control the warning lights around the clock crack and the airbag and seatbelt lights come on. Happened to me. I had it reset a couple of times but within a day or so the lights came back on. Pulled the clock, sent it in for R&R, got it back, reinstalled and no more warning lights. If I had to bet money I would bet that the clock / gage is your problem. Good luck.

I used North Hollywood Speedometer in North Hollywood California. Told them the problem and that I wanted all the connections checked/repaired, all warning light bulbs replaced and I wanted the gauge to look new when I got it back. They said it would be about a 3-4 day turn around. I sent it to them on Monday. They confirmed that they had it on Tuesday (they are local to me). They called with a full estimate on Wednesday ($250-$300 or so). Had it in my hand and then in the car on Thursday.
