Cool is better - Heat Shield for Saab 9-3 ECU (2003-2011)
The problems currently affecting the Saab scene include the engine control units (ECU) for the Saab 9-3 (2003-2011) with the B207 engine. The devices are of an age where they tend to be more susceptible to failure. Replacement as new is difficult or impossible to get. The only way out in the event of a defect is to repair it.
The source of the susceptibility to errors is the high heat in the engine compartment and the unfavorable placement of the control unit (ECU). In contrast to older Saab models, with engines from Saab's own production, it is fully exposed to the heat. The B207 engine is not a Saab in-house development. The engine is based on the GM L850 Ecotec family. It was modified by Saab and adapted for the Trionic (T8).
As a turbo competence center, Saab Powertrain was responsible for all GM brands, the B207 was also installed at Opel as the Z20NET and produced worldwide.
