Hi,
I own a 206SW 1,4 HDi, built january 2002. Last week I got the answer of my question from Peugeot, Germany: beginning in 01/2004 the 1,4 Liter Diesel-engine will get OBD-2. Sorry, but your car -same with mine- is not OBD-2 able. The only way to get all data out is by the official Peugeot service with the DIAG2000 test-equipment.
Best greetings Gerd
P.S.
I tried two different test-equipments: Look at www.obd-2.de or www.obd-2.com
