Whas it 2.5? I had sucess getting them alive with kess v1 in slow mode when they failed in write. btw I always writte them in recovery mode with mpps.
Do you mean 2.5tdi Engine? Then yes, it was 163hp...
If you mean hardware of the Ecu, then I dont know exactly, it was a 8E0 907 401 M...
I made best experience with good old 1260, it has never Failed on this Ecu´s over Obd to me, normally I need no Bootmode then (but this was stolen)...
Without Bootmode: On V6tdi´s 1260 works great, on 1.9tdi Mpps, in my experience... Why it is like this? I don´t know...
But in most cases the Mpps is the better choice, it would have done this Ecu over obd, if he hadn´t pulled the Ignition off, I think, but didn´t gave it a try...
