Thanks again. No luck I don't know how to unlock this car. Ok, about ESL The car has been repaired from big crash, so probably flat battery I see no other source of problem with immo, since the car went to the body shop starting, as I was told.

Remotes work with original eeprom dump, but ESL did not do anything permanently unlocked. About the steering symbol, really don't know, since there are ALL the lights on and most of them blinking At some point, with one of the eeprom try-outs, a functional but not fully working dump, the ESL locked when I removed the key, and has never unlocked again.

I bought new ESL, but I am just connecting it "hanging" just to keep the work When a "functional" dump is written into ccm, the steering wheel lights in yellow, accepts login, can access to adaptation channels, This I forgot to mention. I tried also to flash the ccm to 3AA B or C, but vcp doesn't allow programming session, maybe with odis I could try, although what I have read from other users in other forums, it won't solve it.

Now da Danggg horn won't shut off. Please helo. GuruD7RQT answered 2 years ago. If you installed a new battery and the horn blasts continuously then you have installed the battery backwards!!

This is extremely dangerous. Turn the battery around and this will solve the problem. When the battery is placed correctly, the horn will not turn on. Also note that the replacement of the battery will also trigger other sensors on the dashboard so don't be surprised if other lights come on when you turn your car on. Sue answered 2 years ago.
