Why are the brake lights flickering on my SAAB 9-3 Convertible when the engine management light shows?
I have a 2006 diesel SAAB 9-3 Convertible that showed a 'limited performance' message from engine management and then the brake lights flickered. Although the engine management warning light comes on I am not limited to 40mph. However, rpm seems sluggish and I cannot use cruise control. 7/10 times the warning comes up and sometimes resets itself. The switch under the brake pedal has been replaced and makes no difference. All the brake lights have been removed one by one and this makes no difference. I have no idea what is causing this annoying fault. There doesn't seem to be any damp or wet in the fuse boxes either.
The symptoms suggest that the EGR is clogged up and needs replacing.
