The early L322s up to 2006 share electronics with BMWs of the same vintage.

Being in BMW Transport MODE (aka Energy Saving Mode) is NOT an OBDII error (though most OBDII readers report it as such), and can NOT be 'cleared' like any other PID error. It is a 'mode' of operation that an entire module has been switched to operate in. You will need to use a program that can switch the module back to 'normal' mode, then cycle the module down to standby and back up to running in the 'new' mode.

The (very) cheap P.A.Soft BMW Scanner v1.4.0 can do this quickly and easily for BMW 'E' series modules from about 1994 to 2006+, while newer vehicles often have a 'secret' sequence of dashboard buttons to press.

BUT (there is always a 'but') the versions of Scanner 1.4 and the communication drivers supplied with cheap eBay, aliexpress, etc cables are often incomplete, altered to instal 'pop up programs' (ads), trogenware or are not compatible with current operating systems. Do NOT load the supplied software, see links below for good, secure sources.

On low specification vehicles the Transport Mode is applied to the A/C = Air Conditioning Module, while high spec vehicles switch the BCM = Body Control Module (aka ZKE = central chassis electronics or GM3/4).

Buy a cheap P.A.Soft BMW Scanner v1.4.0 package.
Install the software (from reliable sources) onto a laptop PC.
Install the correct USB drivers for your operating system.
Note that the program startup splash screen will report whether the correct drivers are installed or not, but the program can NOT be run and be tested unless the cable is connected to an OBDII plug in a vehicle !

Connect a charger to a vehicle's battery (unless you are only doing a single, quick reset).
If your scanner has a mode switch set it to 'K bus' mode - NOT 'D-CAN'.
Plug the cable into a vehicle. An LED will light to indicate that battery power is On.
Turn the key to position 2 = Run (do not crank or start the engine). This heavy battery drain is why a charger is needed. (A flat battery is probably what triggered the problem in the first place ...)
Start the program. An LED will flicker if communication is successful.
By default it will run a vehicle identity check first. The information is for display only, the program does NOT check what model the vehicle is (so it will work for BMW, Mini, Range Rover and Rolls Royce too).
Annoyingly all the program's windows overlay each other, so scan the info, then move or delete that 'Information about car' window.

From the buttons at the left of the main window select 'Page 1' of modules. Look for A/C or ZKE on page 1.
Double click the row that starts with A/C or ZKE to access the module's data.
Wait while the module is read.
If the module reports any errors (near top, left of the 'Unit' window) click on the 'Errors ...' button.
If the module is in Transport or Energy Saving Mode, click on the 'Reprogramming' button.
When the 'Used module reprogramming' window pops up it will list the various modes that apply to the module. Click on 'Normal'.
When the module's next startup mode has been set to 'normal' then 'Close' will change from grey to black. Click it.
Congratulations, you are half way there. Some 'normal' functions have been immediately restored, but others will require a restart of the module.
Close the module's window.
Exit the program.
Turn off the ignition.

Have a coffee.

Turn the key to position 2 = Run (do not crank or start the engine).
The module will now wake up in full 'normal' mode.
Congradulations, you are nealy all done. Now clear out any errors that may trigger the mode change again.

Start the program. An LED will flicker if communication is successful.
Move or delete the 'Information about car' window.
Click on 'Scan!'. This will take a few minutes to test every module.
Double click on each line that has errors. Note, there are 3 pages to look at.
Wait while the module is read.
Click on 'Errors ...'
Click on 'Clear errors'. (Takes ~10s per error)
Close the module's window.
Repeat till all errors are cleared (or not). Any that won't clear need a hardware redress.
Exit the program.
Turn off the ignition.

My next post contains software /installation information.

An unadulterated software version that works with 64 bit win7-11 at mega downloads -
https://mega.nz/file/8hIDjQLa#g__VrQnIWQBS...kvNIlUUZn8

This is double packaged, .zip to hold the drivers and the .bz2 installation program. Don't use the drivers from this package.


The program expects to find an old 9 pin serial port connection, so 'Virtual Comm Port Drivers' are needed, AND the Virtual Comm port created MUST be set up to be COM1.

Windows 7-11 drivers (direct from FTDI comms chip manufacturer)
https://ftdichip.com/drivers/vcp-drivers/

Click on VCP Drivers and it will download CDM212364_Setup.zip immediately.
Double click it and run CDM21364_Setup.exe
This will install the drivers directly into the operating system.

To set the virtual Comm Port to be COM1 -
Start Control Panel | Device Manager
Select Ports (COM & LPT)
if the Port is already 'Communications Port (COM1)' fine, get out, otherwise -
Double click Communications Port (COMx)
Select Port Settings | Advanced | COM Port Number | COM1
then OK | OK
and close Device Manager | Control Panel


Start the P.A.Soft BMW Scanner v1.4.0 program to confirm that the drivers are working. But it won't go past the splash page unless connected to a working OBDII plug.

This explains all the capabilities of the program, which are pretty extensive for such a cheap OBDII device.

These PA Soft OBDII devices can be bought for under US$20 - delivered, in 2024.

Besides clearing OBDII error codes the program stored inside it can -

Display live data - this is available from many modules.

Reprogram modules (means setting a module's operting Mode) -
eg if your security module (EWS) and engine module (DME) get out of sync (no crank) it's easy to resync, or if your ZKE goes into Energy Saving Mode it can be set back to 'Normal'.

Coding (means selecting from existing options programmed into a module) -
DME Engine start method, key (de/)activation, IKE units & Service interval reset, etc, LCM testing & options, windows, locking, anti theft. And many others.

EEPROM Read/Write - means the actual rules a module uses can be altered -
eg the range of temperature where the coolant needle stays at 'normal' can be changed from the awful default 75 to 115°C to a much more meaningful 90 to 105°C.
There is an editor included in the program that allows changing values before witing back

Very useful guide.

I have a paid for version of BMW scanner that came with an OBD-USB cable assembly. I have found that my BMW K-Line + DCAN cable with a switch for K Line or D CAN and unfortunately it does not work with the BMW software. I tried your download link and it appears to be exactly the same software as mine which does not communicate fully with several ECU modules on my car. (2003 TD6)

I would be interested to know if your software/cable will communicate with the lighting module on your car as mine gives a not currently supported message when trying to connect to the module. I want to stop cold and hot monitoring of the front LED sidelight bulbs I fitted as they blink alternately ever 30 seconds or so unless turned on due to hot monitoring by the bulb monitoring function. Current: 2003 TD6 HSE. 161,000 miles
