All good points which is why I'd put a scan tool on before replacing anything. The 1.9 Z3 uses a dual temp sensor; one for the temp. gauge on the dash and the other for the ECU, they're built into the same unit. This setup can allow the dash gauge to read properly even though the ECU is getting bad data. The sensor (P/N 13621703993) is readily available for under $15 and takes about 10 min. to replace if it is the source of the problem.
