Hello all, I have the problem with airbag ECU. It began one day in winter and just out of nowhere it broke. The solution is just to change it, but I can't find the component with the same code. According to manufacturer this ecu is the only for my car. But maybe someone tried to put ECU with different last letter? I do not have any other options. Or someone know's, what can happen wrong? For my understanding, there can be different count of airbags, but it's not a big problem, if only it will work. My car is Audi A6 c5 2.7BT 184kW quattro. ECU code is 4B0 959 655 H i can buy 4B0 959 655 J or G.
