1999 996 carrera speedo and tach does not work(analog and digital
I have a 1999 996 Carrera, and I started the vehicle and first, digital speedo meter does not lit up. Right after that, analog speedo and tach were jumping all over the place and it is not operating at all (both digital and analog). Seems like fuel guage, oil pressure guage is working but just speedo and tach is not working at all. I checked fuse, and it looked fine. Do I need a new instrument panel?
None of the digital screen (odometer, clock and etc, which is located at the bottom of the cluster) does not lit up at all, so I thought it maybe a fuse, but seems like all fuses are fine, so do I need a new cluster?None of the digital screen (odometer, clock and etc, which is located at the bottom of the cluster) does not lit up at all, so I thought it maybe a fuse, but seems like all fuses are fine, so do I need a new cluster?

If no sim card is working in the audio unit it is more than likely an audio unit fault but to be 100% sure it needs to go on a Porsche diagnostic machine and read out faults. This is because the audio unit is a module called PCM which controls all the entertainment systems on that vehicle. Also the aerial need to be check but can also be done at the same time
each vehicle is different put the key in the ign. turn key on press door lock/unlock at the same timehold button for 10 sec see if any lights on the dash inst. panel blink if they do that means that the key fob was programmed to your vehicle i recommend a new key fob this will give you definative instructions on how to reprogram your fob
Make sure your battery is fully charged and all battery connections are clean and tight. If the vehicle still makes the clicking noise when you try to start it, then it is your starter solenoid.
When resizing tires, the best method is +1,-1 or -1, +1. That is, if you add to the width one size (i.e. 235 -> 245), then you need to go down one aspect ratio (i.e. 40 -> 35). So if you run 225/40ZR18 tires and want to keep your speedo accurate, 235/35ZR18 works for a "plus one" and 215/45ZR18 will work for a "minus one" change. This way, your impact on speedometer accuracy is minimal.
Start by squirting a little fuel into the throttle body and then crank it and see if it fires up .. if so its a fuel problem if not its going to be something in the electrical. holler if you need more thanks Jerry
it's most likely the cluster if one function works and the other doesn't. And, you likely have an electronic vehicle speed sensor that sends a signal to your analog cluster that then dispays your speed and odometer.
The starter switch must be at fault as this part has the zero ignition and start mechanism itstilled in side of it and the spring load has gone faulty due to ware and tare. so I removed it and replaced with a new one and now everything works as normal.
