Be careful about jumping to conclusions. The E36 TUV certificate may cover the "part family" of raceland coils, basically a set of part numbers (probably regardless of application). The TUV cert is for quality, documentation, and basic strength/reliability type testing done to prove the design. Generally speaking, the E36 and E46 application are similar enough that they may be covered. I can't translate german, but I do know that for fuel cell cars, holding one TUV cert for the fuel cell part numbers enables you to use it in different make and model cars (how I spend my days).
