Autotuner Siemens PCR2.1 Vag.

[pulsar2000]

Anyone know if when Autotuner reads using OBD function, it permantly unlocks ecu ? i see under progress it says
"ECU Unlocked"
Got a slave Autotuner unit, wondering if after i can just do a OBD read with my Kess Master and perform work using this tool? Theoretically speaking ECU has been unlocked / Yes ?
haven`t tried yet or done an ID after reading with Autotuner.
Just a random thought, Anyone have any feedback.
Cheers

In theory would work, but my brain thinks no way. Btw, If you don't try, I can try by myself on next PCR2.1.

Will try soon as have one in next and update, or wait till you try it.

unlock is done on write, not on read

you must unlock inbench to keep ecu unlocked so you can writte/read as many times you like afterwardes without the need to reunlock again

you don't have to unlock on bench, you can unlock on obd with every real tool

So why says unlock when reading? i think i have transcript.

"Keep unlocked"
No it`s either Locked or Unlocked, simple as that, and no you don`t have to read on bench to unlock,

If you want to know realy ecu is unlocked-open ecu , read 25640 and post dump here.

every real tool will tell you if ecu is unlocked or locked on ID over obd
