If you own a Volkswagen Passat B5 (specifically the "5.5" or facelift model produced between roughly 2000 and 2005), seeing the word "SAFE" illuminated on your instrument cluster is a rite of passage you likely didn't ask for.
On the B5.5, a failed brake light switch (a $5 part) will trigger safe mode. If the ECU sees brake pedal and accelerator pedal input simultaneously for too long, it assumes a fault and kills throttle response.
The best way to stop searching is to bulletproof your car.
If you share the and your engine code (e.g., 1.8T AWM, 1.9 TDI AFN), I can give more targeted advice.
