Hi,
"I bought a cable of VAG K+CAN Commander 3.6 to read the PIN code of IMMO 3 in ECU, 06A 906 032HA. However, a technician tell me that the software may make my eeprom of ME7.5 corrupted even during reading the eeprom mode. Is it true?"
I find it very hard to believe a 'technician' which isn't furthermore defined as of which background he has, and knowledge of your specific ecu, to believe.
Especially the tech-support from chinese clone-cable-sellers. Not to mix-up with the
real product-seller of the vag commander (
http://www.abritus72.com).
In the meantime the product has evolved to version 7.1, so there was some development
and bugfixing going on (
http://www.abritus72.com/vagcommander71.html)
According to the web, all versions have bugs. Thats normal for this kinda product. It is
very special and has functions, normal vag workshops cannot do to the range of cars.
Therefore, you always run a risk.
In your situation, you've obtained a cloned product (i will try to also get my hands on one, to test the functionality). So therefore you firstly have to check-out functionality on the workbench with a SPARE ecu.
Build a benchflash-cable, or buy one, and connect the vagcommander clone to it, to see if it
is able to connect and read-out correctly the eeprom. If you need help with this, p.m. me, and i'l get you going.
Post pics and screenshots over here, so all can benefit from your efford.
Don't worry for the moment, as you have the spare-ecu to test on. DO NOT start with
your current WORKING car's ecu to test on. As you may risk the thing the 'technician' said, and corrupt something.
I love to minimise risk and maximise stability. Always be sure, you do stuff on cars, with a fully charged battery, a battery-charger hooked-up to it, chargeing it, and disconnect the radiator's fan's connectors to minimise drain when they suddenly kick-in (this is possible).
Cheers,
