Hi

This is Bosch M 3.8.2 and the Immo is in the ECU - 24C02. It could be done total Immo off. Read the dump and post it.
How about the Immo antena? Is it OK? When you try to program a key, what says the diagnostics? Does it recognized it or no?
If you have the PIN it is very easy to program new key. I`m wondering why it cannot be done.

Regards
