Title: immo3 (passat) immo off -problem- Post by: mkxGTi on January 29, 2016, 03:55:31 PM So according to this pic:
(http://i45.tinypic.com/2czwork.jpg) 02 would mean immo is off. Except when the ecu gets plugged in and auto-scan (vagcom) + dtc cleared results in "Engine Start Blocked By Immobilizer" Any suggestions welcome. Using AVDI(real not vvdi/fvdi). and it also swaps the ecu to 02 from 01 but car fails to start :/ I'd like to keep orig bin and not use (generic) from allroad topic post.

For avdi it appears that the ecu has 01 and both change to 02. Here's full pic of each [immo working] (http://i63.tinypic.com/52yp1z.png) [immo off-not working] (http://i64.tinypic.com/245gi2o.png) edit: vehicle would start then shut-off before immo off. Now just cranks but doesn't start. Title: Re: immo3 (passat) immo off -problem- Post by: ddillenger on January 29, 2016, 04:48:35 PM Your AVDI is writing to RAM. That is not being committed to the eeprom however. I'd be willing to bet that if you re-read it, no changes are made.
Title: Re: immo3 (passat) immo off -problem- Post by: mkxGTi on January 30, 2016, 04:41:02 AM I re-read and changes are there.
Title: Re: immo3 (passat) immo off -problem- Post by: ddillenger on January 30, 2016, 11:41:29 AM I'm sure you did. Re-read the ram.
Title: Re: immo3 (passat) immo off -problem- Post by: mkxGTi on January 30, 2016, 04:46:54 PM I mean. Connect immo off update confdata. Turn off power.. Re init power and read... Same changes.. Lol maybe i should flash generic file.
Doing this all on bench. Title: Re: immo3 (passat) immo off -problem- Post by: mkxGTi on February 04, 2016, 06:25:51 PM Problem solved.
ddillenger: you were correct in the device writes to ram. Only thing i missed was keeping power on while turning off key-on pwr. The eeprom writes from ram once vehicle is sleeping (a.k.a keys are off).

You were writing to ram, but the changes weren't being committed to the eeprom. I could have been clearer with my replies. I apologize for that, but good work! Title: Re: immo3 (passat) immo off -problem- Post by: H2Deetoo on February 05, 2016, 03:31:50 AM What type of ecu is this?

Title: Re: immo3 (passat) immo off -problem- Post by: vwmaniac on February 08, 2016, 08:42:35 AM i have had this problem with vag commander. it will edit the data but as its only committed to ram it is not stored. you need to do read and write in bootmode. i have also noticed that reading the eerpom in vag commander has yielded some interesting result, mostly not all of the data is read.
Title: Re: immo3 (passat) immo off -problem- Post by: mkxGTi on February 08, 2016, 06:08:48 PM What "vag commander" are you using? Reason not all data is read is because they thought it was a fantastic idea to bend ppl over to get as much cash as possible (special functions.. You need 3 to use one properly)

Reason not all data is read is because they thought it was a fantastic idea to bend ppl over to get as much cash as possible (special functions.. You need 3 to use one properly) the free one i downloaded. really only use it to retrieve security login codes. i have 2.5 and 5.1 i believe. Title: Re: immo3 (passat) immo off -problem- Post by: mkxGTi on February 09, 2016, 07:40:46 PM Using real tool (latest). Clones only go so far and the ones i've seen (5.x) do not work well if at all.
