Initiating A Stationary (Parked) Regeneration

NOTE

At starting of the engine, if a stationary

regeneration is required, the engine coolant

temperature must reach 140°F (60°C) before

any stationary regeneration may be initiated

and completed. Permit the engine to idle for a

short while or drive the vehicle until engine

temperature increases sufficiently.

WARNING

Do not initiate a stationary regeneration in a

closed

area

regenerations must be undertaken outdoors only.

WARNING

During

stationary

temperature may reach up to 1200°F (650°C) at

the particulate filter. Before initiating stationary

regeneration, make sure that the DPF outlet

diffuser is clear of objects and that no one is

working near the DPF outlet diffuser.

WARNING

Hot surfaces. Keep yourself clear of all hot

Aftertreatment Device components, particularly

during and after active or stationary regeneration.

Hot surfaces can cause serious burns.

NOTE

STATIONARY REGENERATION

This process requires the vehicle to be parked

while the driver or a maintenance technician

initiates the regeneration process.

The DPF Regeneration telltale light illuminates to

notify the driver of the need and urgency of a

manual stationary regeneration.

DPF REGENERATION telltale light

If stationary regeneration is not performed, this

telltale light will blink, indicating that a stationary

regeneration is required immediately. If stationary

regeneration is still not performed, "engine power

derate and shutdown" sequence may occur as

per level 1 to level 4 sequence.

PA-1639 Operator's Manual 2020 X3-45 Commuter

To initiate a stationary regeneration:

Park the vehicle in a clear area, vehicle

speed must be 0 mph (0 km/h);

Engine must be on normal idle and fully

warmed up (coolant temperature above

140°F/60°C);

Apply

parking

transmission to neutral (N).

Press the DID ENTER button and then get to

the DID Aftertreatment menu. Select sub-

menu Request Parked REGEN and press

ENTER button to confirm and initiate

regeneration.

The regeneration will begin. Turn off the air

conditioning to reduce engine load. The engine

idling speed will increase to 1600 rpm. Once the

regeneration is completed, the engine speed will

return to normal idle.

Voluntary Interruption Of A Stationary Regen-

eration

It is possible to interrupt a stationary regeneration

at all time. To do so, get to the DID's

Aftertreatment menu, select Cancel REGEN and

press ENTER button to confirm. You can stop

regeneration simply by releasing the parking

brake. Use this procedure in order to move the

vehicle in a safe area only.

If regeneration is interrupted, it is very important

to reinitiate the regeneration as soon as possible.

CAUTION

If an active regeneration is stopped repeatedly,

the vehicle may need to be taken to a service

facility. The service facility will use a service tool

to manually initiate the regeneration. Moreover,

the interruption of active regeneration should not

be considered as a normal practice. Some

components of the aftertreatment system might

be damaged in the long term.

CAUTION

To void damages to the system components, do

not set the ignition key to the OFF position to

interrupt a stationary regeneration.
