I would start with cleaning the grounding points (there is a diagram somewhere on here) and the edge connectors and threaded posts on the instrument cluster. I also had some strange issues with my hot water control valve that were solved when I replaced my ignition switch. I never figured out the relationship, but success is success and I was glad to have the problem go away.

No control box on the 968, but almost anything will put the big light on
Low brake fluid level

you may have another dash warning light that has burned out, For example, the oil level light may be burned out but low oil will still turn on the big red light - you just won't have the other light for reference, Turn the key on and, after looking in the owners manual, ensure that all the dash lights that are supposed to come on briefly after ignition is tuned on on are actually coming on. My guess is that's your problem.

The phase capacitor ?
Low Blinker fluid?
Did you use German air when you filled your tires? Very temperamental...

Yes there is three temp senders, blue one at the front is for the ECU for cold starts, the other one is behind that and has two spade terminals, this is for the gauge, there is a third one in the head right in the middle under the fuel cover, this is Oil Temp for the ECU
If you getting nothing back from a blink test then check all the simple things first then if no joy, find a place with a diagnostic tool

No but it should put the engine check light on, and you should see something in the blink test as the knock sensors will be working hard

Quote:Okay, I am also having a weird issue with the warning light.
To be honest, my car sits a lot. It does stay on a trickle charge, so starting isn't an issue.
When I start the car, all is fine, but warning light is on.
It will stay on until I shut the car off, then restart it, then the light goes off, but the restart is not as crisp and quick as the initial start.
If the light comes on during the second start, it will usually go off as soon as the rpm's come up.
It's a little bat-crap bonkers...
I don't do my own wrenching, so I need a few suggestions to let my mechanic guy know some ideas when I take it in for the new front end parts as soon as I can get the unicorn front strut mounts from Posrche....
Thanks folks.
Maybe a silly question, but is your alternator warning lamp working? My Jetta will occasionally display the alternator lamp until the revs rise a little if it's not been driven for a while. Perhaps your 968 is doing the same thing but with a blown alternator lamp, so that only the central warning lamp is coming on instead of both?
