Hi, I have a problem with Lupo 1.2 3L. When i start driving after about 10-20 seconds, the oil light starts flashing. I scan error codes 00263 transmission implausible signal and 01314 engine control module no communication. When I start braking, robot shift from a higher gear to a lower gear, the light stops flashing and flashes again when car stops completely. Please help me ,where to look for problems
