OBC on instrument panel with PCM1

[Rob001]

Got in my 996 C2 MY99 a PCM1 system which I will replace ASAP with a good 2din system from Pioneer or so.

In my car I do not have a stalk to dispay the OBC on instrument panel. This is now only to be controlled on the PCM1 unit and shown on PCM display. Used the search and found the OBC hack with switch or adding a 4 stalk, no problem with that. Question now if the OBC hack will also work PCM1 equipped cars without the oroginal 4 stalk?

You did not need the stalk - the buttons on the PCM 1 controlled what was displayed.

I would have thought that if you remove the PCM1 unit you would be able to enable the OBC in the instrument cluster by doing the hack, and installing the 4-way stalk. The cluster OBC won't give you as comprehensive a display as the PCM1 trip function, but you will get the basics like fuel consumption, range, outside temperature, etc. I'm not too familiar with PCM1, but does the cluster display any trip information now? If not, try getting the OBC coded in the cluster (with a PST2 or PIWIS) and if it shows the outside temperature then you will be OK.

Hi there i'm really interested in the hack what does it do and how do you do it... Does it show temp readings and RPM like the VW/audi display...many thanks
