@inaftanaila, thank you for your quick response and pointing me in the direction of "webasto and WTT".......I am going to do some research. Thank you again.

@MotionInc,
If your profile shows your real car configuration, then your car doesn't have a Webasto heater.
So the Webasto and WTT words won't help you, if by "original eeprom dumps" you were referring to the firmware of each ECU on the car.
BUT,
All ECUs' firmware (and in some cases the configuration too) can be found on the SDD's flash database.
They are files with names that represent the part numbers of the ECUs and with VBF extension, on a folder with an obvious name.
(Sorry don't remember exactly the name as it was looong time ago).

Yes, its impossible with SDD. To be clear, what you need to do with AHCM:

1. If you have not responding AHCM after unsuccessful car Telestart option upgrade or simply AHCM software upgrade - you need add AHCM as NEW. DON'T USE Mongoose Pro cable and SDD on virtual machine. You need an external power source and SDD not higher than 131. SDD downloads all required files for AHCM by itsef.
2. If you need Telestart option - simply take WTT and download to AHCM appropriate dump with Telestart switched on, using special cable, or VAGs K-Line. In first case you may need download dump too. DON'T try switch on Telestart option via SDD!

Thats all.

A strong one for the car. About 20-30 Amps...

Got one of those! It's about 20-25 years old. Thanks guys!

Oh, I forgot.... And several pairs of brown pants.
You'll need them during tactical moments, if you take this road of playing around with flashing and modifying car's software.

If it's simple battery charger - this can be dangerous when programming. Output voltage can bounce depending on load, which changes during programming action. Best solution is intelligent charger with supply option like https://www.ctek.com/products/professional/mxs-25

No problem - for example when you will download software to IPC and in middle of process communication fault occurs - you will get some...some brown pants

^^^^^Yes! I hope I will be able to keep this to a minimum!

Really not so bad - each module has its own bootloader - so you always can rectify it and try again with different interface, computer, with power supply, etc.... excluding case when you upload bad software and module is bricked.

OK, just pulled the proverbial "trigger" on one of these bad boys from Amazon Canada supplied by CTEK North America, a CTEK (56-674) Multi US 25000. Figured I'd like to minimize the possibility of "bricking" ECU chips since my existing battery charger came out of my bass boat (plan was to double up the two 12V banks (15As each). The supply mode was the deciding factor on the CTEK and, of course, Amazon Canada's price. I did forget to order brown pants.......as I have a set of chest waders.

Normally you will get brown pants when you least expect that

P.S. Today Freelander finished, GSM modem with controller installed. Webasto operates as auxiliary and parking heater without any problem's.

For all:

Please REMEMBER: you CAN'T fire Webasto with Telestart(or external controller, Altox, etc., etc.) when coolant temperature isn't lover of 15 degrees of Celsius independently from auxiliary temperature !
