Hello Eduardo,  

thanks for your advise! I disconnected the Lambda sensor, and now the car will restart when warm, although it hesitates and needs some cranking. Anyway, at least a difference! A test drive comes next.  

Does anyone know if the Lambda sensor can be tested for correct function separatly from the car?
