posting here since it's more active then the e83 forum but it should apply since both use a tcu.


i have a 08 x3 and water came in thru the sunroom drain and killed the
tcu combox part number 84109195455.

i can't find any another used tcu with the same part number.

Could i switch and add a different part number one and code it in?

or does it have to be the same part number.

Thanks
