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

You have a poor electrical connection somewhere. Check the connections to the ECU (under the windscreen) and the gear actuator wiring loom connector under the hydraulic unit. While you are there, check the GCU connections (next to the ECU).

When I turn off the engine and start again the light does not come on. Start flashes when driving the gear switches from 1 to 2. Sometimes abs light appears
Which light? Oil pressure light?

Oil light . No error codes if just start the engine or raising the engine speed , i try change gears manualy (when the car is stationary) everything is ok , but when go driving with gear E or manual ,start flashing oil lamp all driving time except when the gear is lowered during braking. Sometimes the ABS light comes on while driving, but when i swich engine off and on again everything is fine again.

It might be a consequence of a poor ECU connection but check the oil pressure with a gauge, just in case. While you are checking the connections under the windscreen, check the drains to the wheel arches either side; if they block, the first consequence is water flowing through the cabin filter on to the passenger side floor.

There's no link between changing gear, braking and an engine oil pressure warning. As above, check the oil pressure with a gauge and check the connections to the ECU.
