That buffer card is in the 240 series instrument cluster. If something similar exists in the 7xx/9xx series, it is embedded deep inside the cluster circuitry.
Personal experience: Swapping instrument panels from different 740 TDs gave different temp gauge behavior. Some stayed near halfway point after warmup, others varied more when climbing hills for example. Same engine, same car, so there is some variation in gauge reaction.
IMHO, for serious temp. monitoring, get an aftermarket sensor/gauge, preferably digital. Factory equipment can be notoriously inaccurate, most likely to avoid complaints from the new purchaser of the vehicle.
The temp gauge sensor is at the front left side of the head, near the #1 GP.
