New Cluster Problems


Recommended Posts

I purchased a 996 instrument cluster and am having a couple unusual problems. The cluster I bought is Part number 996.641.213.00 70c and I put it in my 01 986 S. The problems are that I get a "fuel sender failure, take to workshop" message, and the gas gauge will blink red and will stay on the empty and not move. The other problem is that there is an "outside temperature sensor failure" message. That is to be expected since my car doesn't have an outside temperature sensor. Does anyone have any idea on how to fix the gas gauge? Also, can I use any thermometer to connect to the cluster? I would rather not pay the 20 bucks plus shipping for the stock piece, and if I can use any thermometer I was thinking about relocating it to my air intake to monitor my intake temperatures. If I can use any thermometer, do I just ground one wire and connect the other to what pin location on the cluster? Thanks for the help.

What car (model and year) did the cluster come out of? or is it new?

Did you read the programming procedure that Contributing Member Whall wrote up?

Its from a 2004 996, thats all I know. And I read the write up but didnt see any programming procedure. I've disconnected the battery several times, but to no avail.

Also I forgot to add but my cruise control no longer works. How do I fix that?

Pleased read the write up - putting a Carrera cluster in a Boxster (and having everything work) requires about 1 hour of programming time.

Carrera Instrument Cluster Transplant To Boxster

The article is long but has ALL the information you need to make this mod work great.

Yes, I know. I've read it. Many times. The only thing I could see reprogramming via a PST2 would solve would be the cruise control issue. That doesn't solve the failure to indicate a fuel sender nor tell me the air temperature questions. Everyone else's cluster at least shows a reading for the fuel gauge, regardless if its accurate or not.

If your cluster came from a C4 or C4S then the gas gauge will be wrong. Those are 4WD cars and the gas tank configuration is different. If the cluster came from one of those it will need to be reset.

If you want the outside air temperature then you will need to add a sensor at the front bumper. All Carrera's had this sensor so I don't recall a way to turn it off with a PST2.
