PCMTuner VW Jetta MED17.5.5 Unsupported Tprot Solution

 Problem:

I need help reading Vw Jetta 1.4 ecu med17.5.5 with pcmtuner .. I use module 71 unsupported trot version.. Also I put the diagram im using too.

Solution:

You cannot do this ECU - it has new protection.

Try in boot mode read pass.

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. First check that tc1766 is listed in the bsl module on pcm flash.
