Just replaced my hazard and high beam relays but something is still clicking under my dashboard. Driving me nuts. The porsche Doctor says to push the reset button on the side of the master cylinder. I did my 914 yoga but couldn't see where it is on my 1975 1.8? Any tips??
Note, I recently had low brake fluid levels but that's fixed now.

It is under the rubber boot where the brown/white wire plugs in.

I think I have a similar issue. First it was the switch on the master cylinder and the emergency light would flash. I replaced the switch on the master cylinder. Mine doesn’t have the push button. Flashing gone unless I pull the emergency brake up, but something is still continually clicking under the dash. I need to troubleshoot it someday, but other projects have a higher priority.
