Some pcmtuner users may have problem reading VW Audi ecu med17.5.5 with bench module 71 (error image attached below). It gives error unsupported trot version. How to fix it?
You cannot do this ECU – it has new protection.
Try in boot mode read password.
Open lid and see if it’s a tricore processor. Then try bsl.
You need a good boot pin connection. however some bootloader or bsl (boot system loader pinouts are simply not available for some ecus. both ecu design and ecu help use dimsport which uses GPT to release it without opening lid. So you need to do a search for a bootloader pinout for the ecu type. If you find it then the bsl module certainly should read it.
