Coding a secondhand Airbag ECU, can anyone help please?

Paul Smith · Post by **Paul Smith** » Thu Feb 14, 2019 7:52 pm

Hi,
I've finally got a used airbag ECU for my 2003 Z4 3.0 and after fitting it the airbag light is still on. A pal used a Snap on scanner to read the fault code and the "Safety and Gateway module" shows the error "93AB Incorrect chassis number. He can clear the fault but it immediately returns.

Is there anyone anywhere near Peterborough that has the necessary equipment to code my VIN number onto the new module please? I'm happy to travel, I'd just love my car back!

Thanks, I might take you up on your offer. I asked a few local indies and they all said it couldn't be done except for Bensten Motors in St Ives so I'm taking the car there on Thursday. They say it's not guaranteed to accept my VIN number but they're happy to try.

I am having the same issue with my 2.0l 2005 Z4. Hood was left down and got water into the safety module. Managed to get a second hand unit but now it's throwing an error code that the chassis number doesn't match. I've taken it to a local independent who has tried and failed to code it. Really don't want to go down the route of a new ecu!! To make matters worse he reckons the left and right pillar ecus need replacing at the same time for the system to work. Any help suggestions welcome

Mine's going in tomorrow, hopefully they'll be able to code it. I'll let you know how I get on.

It didn't work!! They say they only use BMW software which I'm pretty sure will never do it. I've now removed the dash and put some black tape over the bulb so that I can get an MOT.

The indy couldn't do it so I'd be grateful for your help. I've covered up the bulb and can hopefully get an MOT, when that's done I'll let you know. Thanks again. Paul

NCExpert: Code to Default
13- Open NCExpert
14-Load profile -> Expertmode -> F1 -> F3 -> choose E60 from the list -> choose any module you want from this list -> now click F6 Back -> select F4 Process ECU -> choose Module -> now click ReadECU -> close the notepad window that showed up after the module was read.

Don't they check that the bulb comes on and then goes off when you start the engine?

Why did you get that in the first place?

Was your car in an accident?

Quick update. Eventually took the z4 to the dealership to see if they could code it. They couldnt and it can't be done as the chassis number cannot be overwritten on the safety ecu. £900 for a new coded safety ecu fitted at the dealer!
