Went into limp mode with M & S lights flashing. Huaband replaced transmission xyz switch & put in a new battery.
M & S lights still coming on and still won't start! It turns over but is not starting. The car has to sit for a while for it to start but then just dies instantly after a little while. Please help. I want my car back. Let me know what I should tell my hubby to check. Thanks.

Hello .. thanks for the donation .. much appreciated

You will need to erase the fault codes from the cars computer memory after a repair of the initial fault or the lights will continue to flash as the cars computer still thinks the fault is present !!

If there is a fault which either prevents all gears being used or disables the kick-down facility, the sport and manual lights will flash at the same time. This indicates to the driver that the vehicle has entered limp home mode. This mode will continue until the ignition is turned off. When the ignition is turned back on and the engine has been cranked, the Electronic Automatic Transmission Electronic Control Unit (EAT ECU) will complete a self-test. If the fault has rectified itself the automatic transmission will resume normal operation and the sport and manual lights will no longer flash. If a fault has been rectified or is no longer present but the fault code has not been deleted, the sport and manual lights will continue to flash until the EAT ECU has diagnosed the fault is no longer present.
If any of the above conditions are true, the software within the transmission EAT ECU will have stored a fault code. After a fault code has been stored and the vehicle has completed 40 warm-up cycles, the vehicle fault code will be deleted from memory providing the fault does not reappear during this time. A warm-up cycle is completed when a running engines coolant temperature rising by at least 61 F ° (16 C °) and exceeding 158 F ° (70 C °). If the fault codes reappear, this counter is reset and requires another 40 warm-ups before the fault is deleted automatically.
