1990 964 Central Informer Lights

Electrical and Electronic

Vehicle Information: Model: 964; Year: 1990; Body Type: Coupe; Total Mileage: 75,200;

Though I have read a number of articles of owners experiencing my problem, I have read no resolution to any. I get the Central Informer alarm with multiple lights repeatedly after the car is driven a few (five) miles; sounds temperature related. I have checked the regulator voltage, no problem. With the assistance of a salvage yard I have replaced the Informer control unit with enough replacement units (five) to realize the control unit is not the problem. All indications clear when the ignition is switched off and back on but return within minutes; very annoying. A local Porsche mechanic (not at a dealership) could not locate the problem. My nearest dealer is over a hundred miles away and I fear parts being replaced without resolving the problem.Region: SoutheastTotal Mileage: 75,200Car Use: Street use onlyModifications: K&N Filter, B & B exhaust and Cat bypass, FI chip
