Symptoms
Symptoms of a B3101 Matra-simca Bagheera diagnostic trouble code may include:
- Possible spark knock (detonation / pre-ignition)
- Poor fuel economy
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

Possible Causes :
- An air leak forward of the DPF will change the sensor readings resulting in the code
- Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks.
- Defective ECU strategies or components will prevent proper regeneration
