Hello all I'm hoping someone out there can help an electrical novice with my daily drive. My car has recently developed a non-start issue. I have the wet carpets problem that so many 986s seem to suffer from. Initially I thought I had fixed the problem with new door liners but it seems my problem may be elsewhere - probably blocked drains. Either way, my car failed to start last week. The central locking doesn't function, interior light is out and the motor doesn't crank. I removed the alarm unit from beneath the passenger seat (RHD UK car) and there was some slight corrosion on the circuitry. This cleaned up ok after a isopropanol bath. However, the no start issue remained after plugging the unit back in. At this point it seems like a simple blown alarm unit. However, I unplugged and replugged the unit a few times and eventually the interior lights turned on again. The motor cranked in to life. I used durametric to check the alarm module - P1571 Immobilizer: Open circuit or no signal. The unit responded to various test through durametric but then stopped responding after a few minutes. I turned off the ignition to attempt a restart and nothing - back to square 1. Even when the engine was running, the central locking remained deffective. Before I spend a probable fortune on a new alarm module, is there anything I can check? It seems weird that the unit functions some of the time after plugging / unplugging multiple times. I've sprayed contact cleaner into the plugs for the alarm module in case it's a connection issue. The Durametric error indicates to me no power is getting to the module - correct? Is there any way to simply remove the immobiliser? Any help would be appreciated as the thought of a 30 mile round commute on a bus does not appeal!
