Engine Stall

If the engine stalls it will coast down in gear, with the transmission providing drive to the engine. A restart can be attempted at this point and the engine may start and the driver can continue.

If the coast down engine speed reduces to less than 400 Revolutions Per Minute (RPM) and the electric ATF pump or the CIMG is not operating:

The engine will stall.
'D' illumination will flash in the IPC .

The driver needs to select Neutral (N) or Park (P) and then press the brake pedal to restart the engine.

Cold Start Neutral

NOTE: The Cold Start Neutral (CSN) function has been introduced on 8P75XPH transmissions for all petrol engine variants from 18MY onwards.

The CSN is a software function. The software function operates when the engine is cold. When the driver selects drive or sport with their foot on the brake, the transmission delays the engagement of gear. This allows the engine speed to remain high. If the driver releases the brake the engine speed reduces to idle and the transmission engages the gear. The function is also exited and the transmission engages the gear if while the driver has their foot on the brake the engine reaches operating temperature.

Previous transmissions would engage the gear when the driver selected drive or sport. This resulted in a noticeable gear engagement. The introduction of CSN will delay gear engagement until either the driver releases the brake or the engine reaches operating temperature. The purpose of the function is to assist in maintaining engine management control during the warm up cycle. Some customers may indicate that there is a delay in gear selection or an elevated engine speed (circa 1, 600 RPM ) but this is normal with CSN.
