A6 C5 2.5TDI v6 immo problem

[razor1199]

Hi,
I have a6 c5 2.5 tdi v6 with coded pump. The pump has been changed, i retrived ECU pin, tried to adapt pump, but VCDS shows me that ECU didn't accept pin with try again after terminal change. With this error i can't do pump adaptation :hmmmm2:. My PIN is (0)2252 as I saw. Maybe the way to solve this problem is use another eeprom dump from another car?

Here is my eeprom (maybe sth is corrupted):

pump are the same number as the 'old' one?
because if is not then you can't match immo

Well, I don't know it exactly, it can be that pump has another numbers (but I'm not sure, I have to ask). But even if it has another numbers, is there any way to match immo? (because I can't even do [Login - 11] - shows error)

if pump swapped so the best way to do immo off ..............but in flash
read ecu and maybe somebody will do off for you

I have done some immo off in VAG group, but never in 2.5 v6 with coded pump, I have heard about properly immo off in eep + flash but then AC didn't work, is there solution to completly immo off with AC kept?

if off made good so all will be fine................

Well, after 2 days I decided to try again, and it worked properly, I think someone tried do something with adapting this pump using wrong login code and ECU has stick. Anyway car is working ;)
