Suggestion · Original poster

I check the M535 module under the seat and cleaned it just in case (no sign of water damage), I also cleaned the ground point under the seat that was slightly rusted and charged the battery but still no luck.

If the fuse keeps blowing, there is likely a short on that circuit.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

HI All, New to me 986.2 has some known issues: - front bonnet doesn't open (only with the release cable) - key remote doesn't work Interestingly, dash receiver is flashing when pressing the key when key is in ignition position. Radio doesn't work either and interior lights only when key is in ignition. I check the M535 module under the seat and cleaned it just in case (no sign of water damage), I also cleaned the ground point under the seat that was slightly rusted and charged the battery but still no luck. Any suggestions to troubleshoot further? Everything else works, as in car start and run and I can lock and unlock doors manually (although I suspect alarm is never armed)

POST 2 / ORIGINAL POSTEROriginal post

Replying to my own post 😅 Issue was with permanent power to the alarm module and more specifically the fuse on said module. Replaced it (guessing it's a 5A) and courtesy light are back and key remote works ... at least once as fuse gets blown again so the saga continues

POST 3Original post

If the fuse keeps blowing, there is likely a short on that circuit. On the 986 it is worth checking the wiring in the door jambs and around the front trunk latch, as those wires can wear and short out.

POST 4 / ORIGINAL POSTEROriginal post

Thanks! Some progress after blowing a few 5A fuses until I realised it was a 15A and replaced the passenger door actuator. "progress" as the car remote now works but then on second opening, fuse blew again after a few seconds while the car was open. Guess is that alarm module tried to lock back and something is shorting it. Got the other door actuator and front trunk one on order but might check those wires. Anything specific to look for and more importantly fix ?

POST 5Original post

You may be able to speed up the process with a Durametric system (or even better the official Porsche PIWIS) if you know anyone who has one...

POST 6 / ORIGINAL POSTEROriginal post

I've got a PIWIS clone and I'll give it a shot. My guess was that fuse blowing would be before anything an ECU could detect but worth a shot.

This is a source reference. Confirm exact model applicability in the original material.
