blinking ! light question ???

[gibson36]

okay so I was messing around the other day while out driving the newer to me 1982 928 and I wanted to try out the cruise so I hit the little arm and the red ! light on the pod started blinking at me so I pulled over and tuned the car off and restarted it no problem checked everything i can think of but that dam light keeps flashing ? ? any clues ?

Its basically a "check Engine" light. Penny would just put a sticker over that.
It should come on when ever most anything is wrong. I see no danger in driving the car though.

Usually when the big red light lights up another light in the cluster lights up so you can read what the problem is. Turn the key to the on position,(when everything is lit before you start it) make sure all the light are lit, compare what should be there to the owners manual. If one is out that may be the warning that is coming up and the bulb is just out. On my car, if you can't "reset" the red light it's a Major malfunction (oil level, ect) Doesn't mean you have one it just means it thinks you do. The fact that it did it when you hit the cruise is odd and it may be creating the issue. Is the cruise off?

A flashing "!" means something of priority is wrong or atleast the control module thinks something serious is wrong. Look in your owners manual and check that all the warning lights are working, generally a flashing "!" means problems with the brake circuit, brake fluid level, engine oil pressure, engine oil level, or engine temp. A solid "!" is less critical and usually means low fuel, anti lock brake, parking brake, coolant level, washer fluid level.... you get the jist.

I'd figure it out before driving any distance just to make sure it isn't a critical system that coincidentally failed with your attempt to use cruise cont.

Interesting that activating the cruise control creates a Critical warning.. I am not not sure of known issues (cause and effect) so, I would look at a wiring diagram to see how the cruise control interacts (maybe something shorting) with the Central Warning System and then check out the WSM for any references.

Maybe someone who has had this one can give better guidance.

i think its a short .... it's not blinking in constant time .... it was on before but i think the cruise made it mad .... i checked everything I know to check it all seems to be working A okay so Im not gonna worry about it I only get a few more weeks to drive it till it snows and I need to start working on the v8 quattro before the snow gets here .....god knows the 928 won't get me to work in that crap ....

The central warning system on these cars comes straight from aviation, DeHavilland, to be exact.

On most modern airliners when a problem is noted a yellow "caution" or red flashing "warning" light on the top of the glare shield [dashboard] will illuminate telling you to look at a flat panel display mounted on the center of the instrument panel where the problem is spelled out. If it is an electrical problem, the computer that runs the planes systems has already isolated the bad bus or generator, and you need only write the problem up in the maintenance log.

Porsche decided that it would be easy to copy this system and install it in a car. It is a very good idea, since it gets the attention of the owner. This system only works when something is really wrong, so you don't get used to seeing it on a regular basis. Frankly, considering several females I have dated, I think that Porsche should have installed an engine disable function should coolant temperature run too high or oil pressure run too low.

[That's not an indictment of the female, just certain members of that group~]

In any case, there is probably a wiring issue. What fuse protects the CIWS? Is it the same as the cruise control? For your year, is the CIWS system on the same plug on the fuse panel as the cruise? Check there. 928 SPECIALISTS ONLINE STORE - 30,000+ 928 Parts - 928 SUPERCHARGER KITS! has all the relays and fuse configurations on their website.

If you can't figure it out, you should consider removing the fuse for the cruise control.
