Hello from Germany,

i own a Seat Ibiza 6L 2005.
It has a broken ECU, it always shows that the lambda probe is broken (heat circuit failure). Lambda probe is ok and the wiring as well.
So we baught a used ECU on Ebay but it does of course not work because the immobilizer does not match. We don't have the login code for the new ECU.

We now like the set the immo off. Seat dealer only wants to sell a new ECU for roundabout 1200€. This is an econimic total loss.
I tried my luck in germans forums, but nobody is able to help.

Are you able to help me and prevent me of having an economic total loss?

The ECU part number is 036906034DG.
We own VCDSpro OBDII as well as BOSCH FSA740.

Thank you in advance,
Thorsten
