Ignition Harness problems with 993

I am in the market for a 993, and I understand that there was an Ignition Harness problem with some 993s which resulted in a recall.  I can't seem to find much information on the problem.  Short of a PPI how do I tell if a 993 has re-call worthy Ignition Harness problem.  Is there a way of telling from the VIN number?

Thank you

What makes my 1998 993 trip computer light to go dim

 I have a 1998 993 with the tiptronic transmission with 28500 miles. The digital display on the trip computer is going dim. The functions work, it is simply the intensity of the light. Th brightness is not affected by adjusting the rheostat for the dash lights. I was told that it could require the replacement of a transistor on the circuit board on the back of the tachometer . Any suggestions?



Door locks on early 993

Door locks are inoperative. Have to open door through window. Alarm will deactivate with remote but no door lock function. Power to module and fuse on module good. Nothing when puish lock button on console including no light on lock button. Lights on doors and bumpers flash when use remote. Neither side will unlock with key. Key only turns in one direction on either door. Please assist.



97 993 c4 cab won't start

Extremely stupid question:  I just bought a 97 c4 cab.  Off the transport it drove great twice, then I left it a couple hours and it is DEAD.  Turn key and nothing happens.  Tried messing with the button on the key, turned alarm on and off, etc.  Will not turn over.  Sometimes the dash warning lights go on when turn key, sometimes not.  Either way no go.  I suspect either a dead battery or some user error related to the immobilization/alarm system.  Can someone explain how this works and how to tell what's up in a systematic way before I get a flatbed and haul it off to repair shop?

Horn started going off intermittently on my 96 993 C4...problem with alarm system?

Over the last few weeks the horn goes off intermittently.  Sometimes when hitting a bump...sometimes when just turning.  Is this a problem with the alarm system or a possible short in the wiring to the horn?

Difficult starting vehicle Do to Imobizler

I am having a difficult time starting the vehicle. The car is a manual shift and I have the clutch depressed to the floor, when I go to start everything normally comes on as expected, however the car does not start. I then have to depress the FOB button when starting and the car will then start. I know it is the imobizler, but not sure how to fix it.

993 Engine Check Light

I have just joined PCA and know there has been much correspondence in the past regarding the dreaded CEL light.  Every year I dread the smog test and spend money to get a mechanic to "turn off" the light for a few miles of relief only, during which I rush to the smog station.  Many mechanics and dealers and dollars later I am so worn out by this cycle that I am even thinking of selling -- although I can't sell it with the CEL on!  There has never been a problem showing with the diagnostics and they say there is nothing to fix.

My radio has turned on twice this winter while the car was off.

I came out to my garafe and my car was locked and the radio was playing.  I was the last person in the car and the radio was off.

How do you program a 1996 911 single button key fob?

My car only had one key and key fob remote, so I purchased a second key and remote. I need to program the single button remote.
