The code stamped on the engine block of my '99 SE is B235EEA00 X_ _ _ _ _ _.
According to the WIS, character positions 8 and 9 are decoded as follows:
00 = basic engine
18 = engine adapted for gearbox w/ automatic clutch
19 = engine w/ oil cooler
20 = engine w/ OBD II
According to this schema, I have the "basic engine". Can anyone elaborate on the other variants?
Is "18" for a semi-automatic transmission for the Euro market (900NG)?
Is "19" for a block-mounted oil cooler, instead of an external cooler?
I don't understand why my block is stamped with "00" instead of "20". I thought all USA 9-5's were OBDII-compliant. Since the WIS delineates between OBDII and non-OBDII Trionic systems, I'd like to follow the correct path. The only easily discernible visual differences are the ECU (hidden) and the presence of two O2 sensors in the OBDII version, vs. one in the basic? Mine has two.
I have a feeling that, in the initial production ramp-up for the US market, some Euro-only parts nevertheless were assembled onto the US cars to keep the production line rolling. (Case in point: my OEM drive shafts are P/N 46 86 655, which are Euro-market only.)
