Saab 9-3 within following VIN intervals:
X7020001 - X7063258, Viggen M99 B235R
Y2000001 - Y2021277, 3/5D M00 B205L/R
Y7000001 - Y7006655, CV/Viggen, M00 B205L/R or B235R
The Trionic T7 engine control modules manufactured before 6 December 1999 have rubber supports for the circuit board that are faulty. These supports contain substances that can accelerate oxidization, which in turn can lead to open circuits on the circuit board. This can produce symptoms such as starting problems and the engine running unevenly. The Check Engine lamp may light up and the car may go into limp-home mode.
Edition 2 of MI 291-2216 should be carried out before this procedure is performed.
